North Korea has likely mastered the technology to power the different stages of an intercontinental ballistic missile and may show it off soon, analysts say, but is likely still a long way from being able to hit the mainland United States.

North Korean state media announced its latest rocket-engine test on Sunday, saying it would help North Korea achieve world-class satellite-launch capability, indicating a new type of rocket engine for an intercontinental ballistic missile (ICBM).

The test showed "meaningful" progress, a spokesman for South Korea's Defence Ministry said on Monday, with the firing of a main engine and four auxiliary engines as part of the development of a new rocket booster.

The announcement of the test came as U.S. Secretary of State Rex Tillerson was in Beijing at the end of his first visit to Asia for talks dominated by concern about North Korea's nuclear and missile programs.

"Through this test, it is found that engine function has made meaningful progress but further analysis is needed for exact thrust and possible uses," Lee Jin-woo, the spokesman for the South Korean defense ministry, told a briefing.

North Korea's state media released pictures of the high-thrust engine test overseen by leader Kim Jong Un, and reported him hailing it as "a new birth" of its rocket industry.

A South Korean expert on rocket engineering said the test was ominous.

"This was a comprehensive test for the first-stage rocket for an ICBM, and that is why it was dangerous," Kim Dong-yub of the Institute for Far Eastern Studies in Seoul told Reuters.

"It appears that North Korea has worked out much of its development of the first-stage rocket booster."

But Kim said the North had still not mastered the atmospheric re-entry technology needed for an ICBM, so it had work to do before being able to hit the United States.

Nevertheless, it might soon demonstrate that it has perfected the system's booster rocket stage.

"What could be next is they would make a new type of ICBM with this new engine system and launch it, but not the entire stages, but to make only the first stage, fly about 400 km and drop.

"They are not going to show it all at once."

Aiming for US?

North Korea has conducted five nuclear tests and a series of missile launches in defiance of U.N. resolutions, and is believed by experts and government officials to be working to develop nuclear-warhead missiles that could reach the United States.

Leader Kim Jong Un said this year the country was close to test-launching an ICBM.

Kim's ambition is believed to be to develop a launch vehicle able to strike a part of the continental United States, most likely Alaska, just over 5,000 km (3,000 miles) from the North's missile test site.

Last week, Tillerson issued the Trump administration's starkest warning yet to North Korea, saying a military response would be "on the table" if it took action to threaten South Korean and U.S. forces.

Experts disagreed in their initial assessment of whether the North's test was for the engine for an ICBM, and for which stage of a rocket it was meant for.

U.S. aerospace expert John Schilling said the engine appeared too big for any ICBM North Korea was working on but would be a good fit for the second stage of a new space rocket it is planning to build.

Joshua Pollack, of the Washington-based Nonproliferation Review, said the design with four verniers, or steering nozzles, was familiar in the North's older, long-range rockets launched to deliver objects previously but said it could be the second stage of a missile, not the first.

"Since the comparable display of 2016 was the first stage of an ICBM, we could speculate that this is the second stage,” Pollack told Reuters in an email.

North Korea fired rockets in 2012 and in 2016 to put objects into space.

Experts say space rockets and long-range missiles involve fundamentally identical technologies, but with different configurations for trajectory and velocity for the stages.

China said on Monday the situation with North Korea was at a new crossroads with two scenarios - a deterioration to war or a diplomatic solution.

"Any chance for dialogue must be seized, as long as there’s hope," Foreign Minister Wang Yi said in Beijing.

NOW WATCH: Terry Crews explains how intermittent fasting keeps him in shape

The first pieces of the US-made Terminal High Altitude Area Defense missile system arrived in South Korea earlier this month, the latest step a deployment process the Chinese government had greeted with chagrin.

Beijing has inveighed against the deployment and criticized the South Korean government for undermining bilateral relations by hosting the missile system.

Chinese citizens, among whom a sense of nationalism is strong, have also taken up the anti-THAAD mantle, protesting and boycotting South Korean businesses and tourism.

Several Chinese state-run media outlets have called for organized voluntary boycotts of South Korean businesses and imports. China is Seoul's largest trading partner, receiving one-quarter of South Korea's exports.

Those public protests have fallen heavily on one company: South Korean conglomerate Lotte Group.

Lotte agreed in early March to turn over a golf course to the South Korean government to host the THAAD missile system.

In the days after, the company said 23 Lotte Mart stores in China were shut down by authorities there, who claimed the outlets were in violation of fire-safety regulations. The maker of one of China's most popular snacks (among other Chinese retailers) withdrew its goods from Lotte Marts in the country, saying it would "never cooperate" with the South Korean company.

Lotte was also ordered to stop construction on a $2.6 billion theme-park project in northeastern China after Chinese authorities suddenly uncovered safety issues. Cyberattacks targeted Lotte websites, shutting them down, and protesters in China's northeastern Jilin province marched with banners reading, "Lotte supports THAAD, get out of China immediately."

Lotte said on March 19 that 79 of its 99 stores in China were facing business suspensions and had been forced to shut down temporarily.

Lotte is heavily invested in the Chinese domestic market, spending nearly $9 billion on its operations there since 1994. The Chinese market makes up nearly 30% of Lotte's sales outside of South Korea.

At present, it has 22 subsidiaries in China, with 26,000 employees and annual sales of about $2.6 billion. Lotte's duty-free business in South Korea pulls 70% of its sales from visiting Chinese tourists.

"Lotte's decision has lit a fuse. When foreign firms touch Chinese consumers' nationalistic feelings, it can spark a boycott," Fu Guoqun, a Peking University business professor, told AFP early this month. "This will have quite a huge impact on the company."

China has also reportedly targeted tourism, pressuring travel agencies there to stop selling group-trip packages to South Korea. Businesses in South Korea's tourism and other industries catering to Chinese visitors also took hits in the days around the THAAD deployment.

Chinese companies have blocked South Korean music videos and TV dramas on streaming services in the country. Chinese broadcasters also reportedly canceled appearances by South Korean bands — moves that garnered support on Chinese social media.

At least one K-pop band, MIXX, has reportedly broken up over the THAAD dispute. A Chinese agency managing the band (it had two agencies representing it; the other was Korean) withdrew its investment, making the band unable to continue its promotions. Three of the group's members, all Chinese, returned to China.

"Money spent on K-pop stars will turn into bullets that point towards you and your family in the future," a posting on China's Twitter-like Weibo service said, according to AFP.

In response, Seoul has gone to the World Trade Organization. A South Korean official, stressing that it was not a legal action, told Reuters that it was a request for the trade bloc to examine if Beijing was upholding trade agreements fairly.

Beijing, which has not directly linked trade and commerce restrictions on THAAD's deployment, did not respond specifically to South Korea's complaint, instead invoking the role of the public in such trade dealings. (The Chinese public has targeted goods from other countries amid international disputes in the past.)

"We support normal business and other exchanges between China and South Korea," a Chinese Foreign Ministry spokeswoman told a news briefing this week. "But everyone knows this needs a corresponding basis in public opinion."

Both the US and South Korea have repeatedly stated the defensive nature of the THAAD missile system, and Chinese military officials have said they have the means to neutralize THAAD batteries.

South Korean lawmakers have stepped up criticism over what they see as a lack of response from Seoul, but direct discussions between the two governments have not been forthcoming, with Beijing declining a request from Seoul to meet at a Group of 20 meeting in Germany this weekend.

Twisting the screws on South Korea's business interests may be a prelude to future deployment of such measures against others.

"What's happening to Korean companies now is a pretty good playbook for what might happen to US firms over the next year," Andrew Gilholm, director of analysis for China and North Asia at risk consultancy Control Risks, told Reuters in early March.

"Rather than the big dramatic trade war, everything goes to hell scenario under Trump," he said, "it's probably more likely to be manifested as regulatory harassment of companies — one of the lower intensity tools for China."

NOW WATCH: Meet THAAD: America’s answer to North Korean threats

At the height of the Cold War, the United States was deploying nuclear weapons all around the country, ready to launch at a moment's notice. While the missiles were never used to strike a foreign target, one did explode in its New Jersey shelter.

China has a new generation of stealthy, supersonic anti-ship missiles, and the US is clearly worried about them. Former US rear admiral Eric McVadon described them as the "strategic equivalent of China’s acquiring nuclear weapons in 1964". He wasn’t exaggerating.

The missiles can evade US missile defenses and undermine the effectiveness of the carrier strike groups the US operates in the Western Pacific.

By deploying them, China could be changing the future military balance in Asia, pulling the centre of power away from Washington and its allies and towards Beijing. If the US can’t sustain its monopoly on the development of precision missile systems, it will struggle to project its current level of power in the western Pacific – and its forward forces and bases in the region will be increasingly vulnerable.

Such a shift, or even the perception of one, carries all sorts of risks. Deterrents might lose their deterrent force; military miscalculations might be made, potentially leading to inadvertent war. Then there’s the arms race factor. Precision strike munitions might soon start to proliferate across the region – Japan, for one, has recently expressed a keen interest in exploring the development of a long-range strike capability similar to the US’s Tomahawk cruise missile.

The missiles that threaten to shuffle the deck were first seen during China’s 2015 Victory Day Parade. The two anti-ship missile variants on display were the DF-21D, a medium-range ballistic missile dubbed the Carrier Killer, and the DF-26 – a long-range, nuclear-capable version.

The DF-26 is the first conventionally armed Chinese ballistic missile capable of reaching the Pacific US territory of Guam, and is thus known as the Guam Express (or Guam Killer). If paired with a nuclear warhead, it will be China’s first long-range nuclear precision missile capable of targeting vital US military assets in Asia.

These weapons allow China to both project its military power further and enhance its strategic deterrence – all without the political risks of large troop deployments, or the enormous costs of multiple aircraft carriers.

Off-balance

This slow-brewing arms race is quite different to the US-Soviet precision strike competition during the Cold War. This time around, domestic political considerations are front and centre: if the Chinese Communist Party wants to preserve its mandate, it has to prove its ability to defend China’s so-called core interests, among them the South China Sea.

But simply being able to show off this sort of military prowess perfectly fits China’s aspirations to become a great power. These assets can threaten US aircraft carriers, overwhelm its missile defenses and threaten its strategic hub in Asia. They also reinforce China’s already formidable military tool-kit designed to settle Beijing’s unresolved interests in the Taiwan Straits, and the increasingly militarized disputed islands in the South China Sea. Even untested, the missiles’ symbolic weight is enormous.

NOW WATCH: Your neighbor's WiFi is ruining yours — here's how to fix it

HONG KONG/BEIJING (Reuters) - China is steadfastly opposed to the deployment of advanced U.S. anti-missile radars in South Korea because it does not know whether the defenses, intended for North Korean missiles, are capable of tracking and countering Beijing's own nuclear program, experts say.

Beijing's resistance to the THAAD (Terminal High Altitude Area Defense) anti-missile system put up south of Seoul has become a major thorn in bilateral ties with the United States and is bound to be discussed at this week's summit meeting between President Xi Jinping and President Donald Trump.

While the United States says THAAD is needed to protect Seoul from the threat posed by North Korea's growing nuclear and missile programs, some Chinese strategists believe it is also a threat to the viability of China's nuclear deterrent.

"It is clear that there is no one in China who really knows the technical capability of THAAD and that's part of the problem," said Zhang Baohui, a Hong Kong-based mainland expert on China's nuclear deterrent.

"THAAD's full capabilities are secret so there is a real knowledge gap among Chinese strategists. If they are misplaced, they are at least genuine in their concern — they have to assume a worst-case scenario."

Officially, China says it objects to THAAD because it will destabilize the regional security balance.

Chinese officials have also expressed concern about the reported 2,000 km (1,200 mile) range of THAAD's powerful X-band radars, which can look deep into the mainland, rather than the system's shorter-range interceptor missiles that can target North Korea's missiles.

Besides casting a shadow over U.S.-China ties, THAAD has also ruptured the relationship between Seoul and Beijing.

Chinese authorities have closed dozens of Lotte retail stores on the mainland after the South Korean conglomerate agreed to provide land for the missile defense system.

There has been a sharp decline in Chinese tourists going to South Korea, while South Korean singers and actors have been blocked in various ways from reaching a mainland Chinese audience, and dozens of Korean-focused blogs suspended in China.

Never tested

THAAD, never tested in a conflict and whose effectiveness is still questioned by some Western experts, is designed to intercept and destroy ballistic missiles late in flight, either just inside or outside the earth's atmosphere.

The range of its radars however can help the system cover missile and rocket launch sites deep in China's isolated northeast where the People's Liberation Army (PLA) tests its modern generation of long-range weapons, some Chinese experts fear.

China's nuclear deterrent is based around ensuring it has a credible "second strike" capability given its long-standing vow never to be the first to use a nuclear weapon in a conflict.

Beijing is rebuilding its arsenal of mobile intercontinental ballistic missiles, as well as a fleet of submarines capable of firing such weapons, to ensure the so-called survivability of that deterrent.

Some Chinese scientists fear that the THAAD radars are sophisticated enough to allow the United States to track tests and specific missile signatures, ultimately helping it better prepare to counter any future Chinese attack.

Li Bin, a security expert at Beijing's Tsinghua University, wrote recently that the THAAD radars would allow the U.S. military to obtain data on missiles that it could not get through other sources, clearly undermining China's nuclear strategy.

In another recent commentary, Li noted differing unofficial Chinese views over the range of THAAD's radars, a discrepancy he said pointed to a lack of knowledge.

Some experts have however stressed that the PLA has both hard and soft options for crippling the THAAD's radars, such as the use of laser weapons or, less provocatively, deception maneuvers to confuse them.

Peng Guangqian, a strategist at the PLA Academy of Military Science, told the state-owned Global Times tabloid earlier this month that it was easy to "blind" the radars.

"We can also make THAAD useless through electronic interference and feigned military activities, because such activities can interrupt the functioning of the THAAD system."

Beyond debates over the THAAD's range, mainland strategists believe the system can be linked into a broader U.S.-led network of early warning radars, sensors and battle management systems in the region and tie in neighboring nations into an alliance.

Yao Yunzhu, a retired PLA major general, warned a Shanghai conference last month that such a network ultimately targeted China.

And that, say experts outside China, lies at the core of Beijing's fears over THAAD — a South Korea tied ever more tightly to the U.S. and Japan, despite years of effort by Beijing to draw Seoul closer.

Former U.S. Defense Secretary William Perry told the conference that he believed that China's missile forces were large and sophisticated enough to be impossible to defend against, so THAAD need not be a concern to Beijing.

He did say, however, that it "conceivably could enhance" other missile/anti-missile systems in the region.

NOW WATCH: Meet THAAD: America’s answer to North Korean threats

BEIRUT (Reuters) - U.S. missile strikes on Syrian military positions serve the goals of "armed terrorist groups" and Islamic State, the governor of Syria's Homs province said on Friday.

"Syrian leadership and Syrian policy will not change," Homs Governor Talal Barazi said in a phone interview with state television. "This targeting was not the first and I don't believe it will be the last," he added.

U.S. President Donald Trump said he ordered missile strikes against a Syrian airfield from which a deadly chemical weapons attack was launched this week, declaring he acted in America's "national security interest" against Syrian President Bashar al-Assad.

U.S. officials said the military fired dozens of cruise missiles against the airbase in response to the suspected gas attack in a rebel-held area that Washington has blamed on Assad's forces.

The Syrian government has strongly denied responsibility.

"The armed terrorist groups and Daesh failed to target the Syrian Arab Army and Russian military positions," Barazi said, using the Arabic acronym for Islamic State. The Syrian government describes all armed groups opposed to it as terrorists.

The U.S. strikes "targeted military positions in Syria and in Homs specifically" in order to publicly "serve the goals of terrorism in Syria and the goals of Israel in the long run," Barazi added.

A Syrian military source said earlier the attack on the Syrian air base had led to "losses."

"I believe - God willing - that the human casualties are not big, but there is material damage. We hope there are not many victims and martyrs," Barazi said by telephone to Reuters.

He said rescue and fire-fighting operations had been going on for two hours.

NOW WATCH: Here's what those white marks on your nails say about your health

Since the Tomahawk cruise missile made its combat debut in 1991, more than 2,000 missiles have been launched in support of U.S. combat operations, according to Raytheon, the munition’s current producer.

So what is this missile that’s been a stalwart of U.S. military operations more than 25 years? It’s an intermediate-range cruise missile, able to travel 800-1500 nm, that can quickly and accurately carry a 1,000-pound conventional warhead to a target after being fired from a ship or a submarine.

The key to the Tomahawk’s success lies in its ability to project power hundreds of miles away, and avoid putting pilots in danger. On April 6, when the U.S. launched 59 cruise missiles at an airbase controlled by Syrian leader Bashar al Assad, the destroyers that dispatched the missiles were on the other side of the Mediterranean Sea, hundreds of miles away, closer to Europe than to Syria, retired Army Maj. Gen. James “Spider” Marks said on CNN.

Despite its combat record, the Navy is looking to stop ordering Tomahawks from Raytheon in the coming years, and will ultimately replace them with a next-generation cruise missile.

“This is an old missile, in one sense,” Tom Karako, a senior fellow at the Center for Strategic and International

Studies, told Yahoo Finance. “But in another sense, it’s being continually modernized. It’s frequently the thing for which we reach first in these kinds of engagements.”

But what will replace the critical Tomahawk? We don’t know yet.

“[W]e are moving forward with development of what has been referred to as next-generation land-attack weapon,” acting Navy Sec. Sean Stackley told the House Armed Services Committee in 2014, when he was the Navy’s acquisition chief. “And the key elements of that weapon will be its increased lethality, survivability beyond what Tomahawk brings today.”

In the interim, the Navy is still stocking up on Tomahawks.

According to Defense One, the Trump administration has asked Congress for $85 million to buy an additional 96 Tomahawk land attack missiles. That’s on top of the $187 million the Navy asked for to buy 100 new TLAMs last year. But really, how do you put a price on a warhead that chief executives can use to project power at a moment’s notice? In our politically divisive age, that’s something politicians on both sides of the aisle seem to agree on.

NOW WATCH: People are outraged by a Pepsi ad starring Kendall Jenner — here's how the company responded

SEOUL (Reuters) - A North Korean missile "blew up almost immediately" on its test launch on Sunday, the U.S. Pacific Command said, hours before U.S. Vice President Mike Pence was due in the South for talks on the North's increasingly defiant arms program.

The failed launch from the east coast came a day after North Korea held a military parade in its capital, marking the birth anniversary of the state founder, in which what appeared to be new long-range ballistic missiles were on display.

Pence is due in Seoul at the start of a 10-day trip to Asia in what his aides said was a sign of the U.S. commitment to its ally in the face of rising tension over North Korea.

President Donald Trump and his military team are aware of North Korea's missile launch, U.S. Defense Secretary Jim Mattis said in a statement on Saturday. Trump has no further comment on the matter, Mattis said.

A U.S. nuclear-powered aircraft carrier strike group was also heading for the region.

The North has warned of a nuclear strike against the United States if provoked.

"The North attempted to launch an unidentified missile from near the Sinpo region this morning but it is suspected to have failed," the South's Office of the Joint Chiefs of Staff said in a statement.

The U.S. Pacific Command said the missile "blew up almost immediately", adding the type of missile was being analyzed.

South Korea's Yonhap news agency cited an unnamed South Korean intelligence source as saying the missile appeared to have not flown far from its land-based launch site.

The North launched a ballistic missile from the same region earlier this month ahead of a summit between the leaders of the United States and China, its key ally, to discuss the North's arms program.

A U.S. Navy attack on a Syrian airfield this month with Tomahawk missiles raised questions about Trump's plans for reclusive North Korea, which has conducted several missile and nuclear tests in defiance of U.N. sanctions, regularly threatening to destroy the United States.

Sinpo, where the launch took place, is the site of a North Korean submarine base and where the North has tested the submarine-launched ballistic missile (SLBM) it is developing.

The missile launched earlier this month flew about 60 km (40 miles) but what U.S. officials said appeared to be a liquid-fueled, extended-range Scud missile only traveled a fraction of its range before spinning out of control.

“It appears today’s launch was already scheduled for re-launching after the earlier test-firing” Kim Dong-yub, a military expert at Kyungnam University's Institute of Far Eastern Studies in Seoul.

“This launch can possibly be a test for a new type of missile or an upgrade,” Kim added.

The North has said it has developed and would launch a missile that can strike the mainland United States but officials and experts believe it is some time away from mastering all the necessary technology.

Tension had escalated sharply in the region amid concerns that the North may conduct a sixth nuclear test or a ballistic missile test launch around the April 15 anniversary it calls the "Day of the Sun."

The White House has said Trump has put the North "on notice" while the possibility of U.S. military action against Pyongyang has gained traction following U.S. strikes against Syria on April 7.

Impoverished North Korea and the rich, democratic South are technically still at war because their 1950-53 conflict ended in a truce, not a peace treaty. The North regularly threatens to destroy the South and the South's main ally, the United States.

Iran wants to turn Yemen into a "missile base" from which it can threaten Saudi Arabia, according to a Saudi general.

Saudi Gen. Ahmed Asiri claimed Saudi Arabia prevented an "Iranian plot" from threatening the country’s security and stability in an interview with Saudi Arabia’s al-Arabiya news Sunday.

He added that the Iranians planned to use Yemen’s Houthi rebels to implement their scheme, allowing Iran to deploy missiles and use Hezbollah suicide bombers against the country.

Saudi Arabia "did not need to wait for Yemen to become another missile base that threatens the security and safety of Saudi Arabia, as the Iranians planned to do, to turn Yemen into a military base, from which they could attack the kingdom," said Asiri, who serves as both the spokesman for Saudi operations in Yemen and as advisor to the defense minister.

Houthi rebels have targeted Saudi Arabia with 48 ballistic missiles since the country began joint military operations with other Arab states in Yemen in 2015. He said a total of 138 missiles have targeted either Saudi territory or its forces. It is believed that Iran, which has one of the largest military stockpiles in the Middle East, is supplying Yemen’s Houthi rebels with military equipment.

The Houthis (also known as Ansar Allah) are a rebel group from Yemen’s northern region. They have fought against the Yemeni government since 2004, including the current US and Saudi supported government of President Abd Rabbuh Mansour Hadi. Yemen is currently divided between Hadi’s government and the Houthi rebels.

Saudi Arabia has been criticized for killing civilians while fighting the Houthis. More than one-third of Saudi strikes in Yemen have hit civilian areas, according to a study by the Yemen Data Project released in September.

Asiri claimed that Saudi Arabia has shown restraint by avoiding a ground-based operation.

"It did not happen for several reasons: First, there would have been be a large deployment of ground forces which would have resulted in a large number of civilian and military casualties. One of the objectives of the coalition is to rid Yemeni civilians of the Houthi rebel presence in their daily lives," said Asiri. "There are around 100,000 Saudi forces stationed on the border that could have occupied Yemen in a few days, but we wanted to support legitimacy in Yemen with the least possible losses on both sides. We are like a technical team in a hostage situation."

Asiri said Saudi Arabia aims to support the Yemeni government and prevent Houthi incursions in Saudi territory. He claimed that the Saudi-led coalition has made progress in beating back the rebellion. However, the Yemeni capital of Sanaa is still under Houthi control, while several other cities are in contention.

NOW WATCH: Meet the MQ-25A Stingray — the US's response to threats like China's 'carrier killers'

When North Korea rolled out a few submarine-launched missiles for the first time over the weekend, some observers noticed that the trucks belonged to a Chinese company — Sinotruk.

North Korea celebrated the Day of the Sun, the anniversary of the birth of North Korean founder Kim Il Sung, with a military parade, during which the regime showed off its weapons for war. Half a dozen KN-11 SLBMs were displayed during the show, and they were brought out on Chinese vehicles.

Some observers also suggested that the trucks carrying a potential intercontinental ballistic missile model were also of Chinese origin. There were also North Korean military trucks on Chinese tires produced by Triangle Group.

The UNs prohibits the sale of military equipment to North Korea, but dual-use products are harder to regulate and even harder to track. Both Sinotruk and Triangle said they were unaware that their products were used in North Korea’s military parade. A Sinotruk HOWO vehicle was used to showcase a North Korean artillery system last year.

"From my understanding, we haven’t had any business with the North Korean market since last year," a Sinotruk representative told Reuters, adding, "North Korea has never been a major focus of ours."

The company suggested that the trucks may have been refitted.

Referring to the tires, a Triangle Group representative said, "It’s possible they were resold from somewhere else."

While there is the possibility that Chinese companies knowingly exported dual-use goods to North Korea with advanced knowledge of North Korea’s intent, there is no immediate evidence. In 2010, North Korea’s forestry ministry told China that it needed heavy trucks to haul timber.

Chinese trucks have also been used for mining and construction.

At the same time, Chinese companies have been involved in the shipment of banned technology to North Korea. A recent Wall Street Journal report revealed that North Korean missiles are being developed using components imported from China. The report said that North Korea would not have been able to advance its missile program to the levels seen today without Chinese assistance. It is unclear if the Chinese state government was simply unaware or complicit, but the report demonstrated the difficulty in cutting North Korea off and isolating the country from the world.

It is unclear how much China will cooperate with the Trump administration’s efforts to rein in North Korea, as the relationship between Beijing and Pyongyang and Beijing and Washington are both complicated.

China is adamant that it upholds international law and all related UN resolutions. "As a permanent member of the UN Security Council, China strictly adheres to its international responsibilities," Chinese Ministry of Foreign Affairs spokesman Lu Kang said, replying to questions about the trucks in North Korea’s parade.

NOW WATCH: Children who eat too much sugar are developing diseases that only alcoholics used to get

North Korea's state television aired footage of a musical show marking the birthday of founding father Kim Il Sung, which ended with a mock-up video of missiles engulfing the United States in flames.

A choral performance attended by Kim Jong Un, the elder Kim's grandson, was held on Sunday (April 16), a day after a huge military parade in Pyongyang, which also marked the 105th birth anniversary of Kim Il Sung. 

The singing was followed by footage of its test-firing of a missile in February which, in the video, was joined by other missiles shooting into the sky, passing over the Pacific and hitting several targets in the United States in giant balls of flames.

North Korea said in February that it had successfully tested a new type of medium- to long-range ballistic missile, the Pukguksong-2, propelled by a solid-fuel engine.

Pyongyang regularly threatens to destroy the United States and amid heightened tension on the Korean peninsula, it has escalated a war of words, warning of full-out nuclear war if Washington takes military action against it.

A close review of photos from North Korea's recent military parade shows that the Kim regime may be closer to building a functional nuclear missile that can threaten the US mainland than previously thought.

While some experts doubt that all the missile launcher tubes driving around Pyongyang really held missiles or posed a much of a threat, Michael Duitsman, a research associate at the Center for Nonproliferation Studies, warned of a small but troubling detail on one of the missiles.

In the picture below, on the right side of the missile, where the cylindrical section meets the nose, the fuselage appears to have been wrapped.

Here's a closer look:

Duitsman told Business Insider in a phone interview that this may be wound filament-reinforced plastic, a very light alternative to metal that can withstand the incredible pressure of rocket motors. Tal Inbar, the head of the space research center at the Fisher Institute for Air and Space Strategic Studies, first pointed this out.

"Part of the parade is them showing us what they're working on," Duitsman said. "Not stuff that's operational, but stuff they're actively working on. They're showing us their intentions."

Duitsman said wound filament-reinforced plastic has up to 10 times the strength-to-density ratio of aluminum and could greatly reduce the weight of a missile.

Referring to the booster portion of the missile as a stage, Duitsman said, "The lighter the stage is, the less propellant you need and the more you can put on top of it." In this case, a lighter missile could be used to carry a nuclear warhead.

While it seems like a small detail, Duitsman said that the Soviets and the US made similar breakthroughs when creating their ICBMs. Ultimately, if the North Koreans had advanced composite materials and plastics in this part of their missile design, it would mean they're further along in their program than many experts suspect.

Though the North Koreans would still face problems in launching and steering the missile, Duitsman said they could begin testing an ICBM that could reach Washington in as little as two or three years.

Iran’s communications minister recently announced plans to put two satellites into space, but the impending launch may be cover for ballistic missile research.

Mahmoud Vaezi announced on Monday that the two supposedly home-made satellites will be launched into orbit in the coming months.

The launches may seem innocuous, but such space technology could be used to help advance Iran’s missile technology.

"Iran is certainly using its satellite program to shield the ICBM (inter-continental ballistic missile) program. The technology and challenges in the two programs are similar in many aspects and one can move from one to another," Saeed Ghasseminejad, an Iran research fellow at the Foundation for Defense of Democracies, told The Daily Caller News Foundation.

Iran needs to disguise its ICBM program, he added, and satellite launches are an ideal method. The Islamic Republic has been sanctioned by the US for its missile tests in the past, even since the signing of Joint Comprehensive Plan of Action nuclear agreement in 2015. Iran’s military has engaged in at least 8 missile launches since the deal was inked, according to a Times of Israel report.

Iranian state media claimed the two satellites, the Nahid 1 and Payam-e Amir Kabir, are "home-made." The Nahid is reportedly a telecommunications satellite, while the Payam-e Amir Kabir takes images.

Iran’s missile arsenal forms the backbone of its national defense. The Islamic Republic was cut off from Western military support after its revolution in 1979, diminishing the capabilities of its air force. The country instead focused on advancing its missile program, which was easier to maintain thanks to the help of North Korea. An Iranian missile tested in January had North Korean origins, according to the Pentagon.

Missile tests are technically not a violation of the JCPOA, but they do violate a separate United Nations Security Council resolution.

Ghasseminejad said Iran continues to progress its ICBM program so that it can field a nuclear weapon in the future. He suggested the US target the various industries involved in advancing Iran’s ICBM program in order to curb a future threat.

China's vocal opposition to the deployment of the US's advanced anti-missile system THAAD has previously been limited to official statements and public demonstrations.

Now that rebuke has a new, more melodious form: a rap video.

A video featuring Chinese rap group CD Rev, based in the south-central province of Sichuan, appeared earlier this month, as reported by The New York Times on Friday, racking up nearly 50,000 views as of Friday morning.

The deployment of THAAD, which began at a site in southeastern South Korea in March, has sparked months of protests in China.

State-run media outlets have called for protests of South Korean businesses and imports, and demonstrators have targeted the conglomerate Lotte in particular. (South Koreans have also targeted Lotte for protests.)

China's ire has also affected tourism to South Korea, and Chinese broadcasters have cancelled appearances by South Korea bands.

The lyrics in CD Rev's video, in both English and Chinese, criticize the deployment of THAAD in tones likely to be taken as patronizing by some in South Korea.

"How many times do I have to warn you my lovely little neighbor boy? You don’t really want that little toy, you know," one member of the group raps near the start of the video, continuing:

"Your big brother is annoyed. Tryna avoid the sight of me and install a camera in my room. You always got so many faces. Or maybe I could avoid some of those small cases. But not this time kid you going to far. The things you doing now is gonna rip you apart."

The video — featuring backgrounds like Bird's Nest stadium built for the 2008 summer Olympics as well as footage of THAAD's deployment — also appears to level criticism at some people in China for the fervor of their anti-THAAD protests.

"I don’t want to see South Korea with this attitude and I also don’t want to be reminded of the war between the two sides because now this area is in peace," a member of the group raps in Chinese.

"Why not choose us rather than Uncle Sam? This situation seems to be out of control. Also, I hope that every time such international affairs like THAAD arise, we can be aware that we should keep calm and not be rude or angry with our fellow countrymen. This is China and we just want peace and love instead of bullets and bombst [sic] but if anyone is trying to cross the line, we will show them something."

The Chinese public is not the only group inflamed by THAAD's deployment.

South Koreans have protested the anti-missile system's arrival in their country for months.

They are concerned about the system's sophisticated radar, the potential for it to be a target during a war, and about the health and environmental effects of its deployment.

"No THAAD, No War,"protesters chanted in Seongju, a town that THAAD equipment passed through on its way to its deployment site. "Hey, US! Are you friends or occupying troops?"

NOW WATCH: The US's most advanced missile system is operational in South Korea — and it has China and Russia alarmed

SEOUL (Reuters) - North Korea fired a ballistic missile early on Sunday that flew 430 miles, South Korea's military said, days after a new leader took office in the South pledging to engage in dialogue with Pyongyang.

The missile was fired from the region of Kusong, northwest of Pyongyang, where the North in February successfully test-launched an intermediate-range missile that it is believed to be developing.

Japan said the latest missile reached an altitude of more than 1,245 miles and flew for 30 minutes before dropping into the sea between North Korea's east coast and Japan. The North has consistently test-fired missiles in that direction.

Sunday's launch, at 5:27 a.m. Seoul time (4:27 p.m. ET), came two weeks after North Korea fired a missile that disintegrated minutes into flight, marking its fourth consecutive failure since March.

The U.S. Pacific Command said it was assessing the type of missile but it was "not consistent with an intercontinental ballistic missile".

"U.S. Pacific Command is fully committed to working closely with our Republic of Korea and Japanese allies to maintain security," a spokesperson said, referring to South Korea by its official name.

In a statement Saturday evening, the White House pointed out the proximity of the missile to Russia, and said President Donald Trump "cannot imagine that Russia is pleased."

“North Korea has been a flagrant menace for far too long," the statement said. "Let this latest provocation serve as a call for all nations to implement far stronger sanctions against North Korea."

South Korean President Moon Jae-in, who took office on Wednesday, held his first National Security Council meeting as president in response to North Korea's latest missile launch, which he called a "clear violation" of U.N. Security Council resolutions, the presidential office said.

"The president said while South Korea remains open to the possibility of dialogue with North Korea, it is only possible when the North shows a change in attitude," Yoon Young-chan, Moon's press secretary, said at a briefing.

Moon won Tuesday's election on a platform of a moderate approach to North Korea and has said he would be willing to go to Pyongyang under the right circumstances, arguing dialogue must be used in parallel with sanctions to resolve its neighbor's defiance of the international community.

Japanese Prime Minister Shinzo Abe told reporters on Sunday that North Korea's repeated missile launches are a "grave threat to our country and a clear violation of UN resolutions."

Abe said Japan will stay in close touch with the United States and South Korea.

Japan Chief Cabinet Secretary Yoshihide Suga declined to comment when he was asked whether the latest missile launch was a success, and whether it represented a new level of threat.

Missile tests at unprecedented pace

North Korea launched the Pukguksong-2 missile, an upgraded, extended-range version of its submarine-launched ballistic missile (SLBM), from the same Kusong site on Feb 12.

South Korean and U.S. military officials said the February launch was a significant development as it successfully tested a solid-fuel engine from a mobile launcher. The missile flew about 500 km with an altitude of 550 km.

It represented a more significant threat because of the difficulty of tracking a mobile launcher and because of the ability to keep the missile fueled in advance, unlike liquid fuel rockets.

The North attempted but failed to test-launch ballistic missiles four consecutive times in the past two months but has conducted a variety of missile tests since the beginning of last year at an unprecedented pace.

Weapons experts and government officials believe the North has accomplished some technical progress with those tests.

Trump warned in an interview with Reuters in late April that a "major, major conflict" with the North was possible, but he would prefer a diplomatic outcome to the dispute over its nuclear and missile programs.

On Saturday, a senior North Korean diplomat who is a veteran member of its nuclear negotiating team, said the country was open to dialogue with the Trump administration under the right conditions, without elaborating.

Choe Son Hui, the North's Foreign Ministry director general for U.S. affairs, spoke to reporters while in transit in Beijing after attending a conference with former U.S. officials in Norway.

South Korea, the United States and other regional powers have been stepping up efforts to diffuse tensions over the North's weapons program after a sharp rise in tensions in April over concerns that it may conduct a sixth nuclear test.

North Korea has briefly reported on Moon's election win and said conservatives in South Korea should be thrown out for good for inciting confrontation between the rival states.

There was no immediate reaction from China. Delegations from Washington, Seoul and Pyongyang are gathering in Beijing on Sunday to attend China's new Silk Road forum, its biggest diplomatic event of the year.

NOW WATCH: This animated map shows how religion spread across the world

SEOUL, South Korea — North Korea's latest ballistic missile test may be nearly as big a deal as the country's propaganda machine claims.

Though outside experts see several places where North Korea is most likely stretching the truth, the missile launched Sunday appears to be the most powerful the country has ever tested. Some analysts believe the missile, if proved in further tests, could reach Alaska and Hawaii if fired on a normal, instead of a lofted, trajectory.

There's also a political victory for North Korea. The test gives a boost to leader Kim Jong Un as he seeks to show his people that he's standing up to America and South Korea. And it also lifts scientists in the authoritarian nation who are working to build an arsenal of missiles with nuclear warheads that can reach the US mainland. They're not there yet, but tests like this are the nuts and bolts a successful weapons program needs.

Here's a closer look at what happened in Sunday's missile launch, which came only a few days after the inauguration of a new South Korean president, and why it's viewed as a worrying development by North Korea's neighbors and Washington.

The missile

Even before North Korea gave its account of what happened, the launch caught the eye of experts.

Tokyo clocked the missile as traveling about 500 miles and reaching a height of 1,240 miles during its half-hour flight.

That is a higher altitude and longer flight time than any other missile the country has test-launched, according to several South Korean analysts reached by the Associated Press.

North Korea's state media generally confirmed those estimates. It said the newly developed Hwasong-12 flew as high as 1,310 miles before landing in a targeted area in the ocean about 490 miles from the launch site.

North Korea said it fired the missile at a high angle to avoid neighboring countries.

If it had been fired at a normal angle, analysts say, it could have flown much farther — estimates vary between 2,500 and 4,350 miles, the upper number putting Alaska and possibly Hawaii within striking distance.

"This is a very uncomfortable development for the United States," said Lee Illwoo, a Seoul-based commentator on military issues.

Before Sunday's launch, an intermediate-range missile called Musudan was thought to have the longest potential range among the missiles that North Korea had test-fired — about 2,180 miles. That could strike US military bases in Guam. During a 2016 test, the Musudan reached a height of 880 miles.

In recent years, North Korea successfully put satellites into orbit twice aboard long-range rockets in what the UN called a disguised test of long-range missile technology. But the country has never carried out test flights of those rockets' military versions.

The nuke

Outsiders express more skepticism about North Korea's nuclear-warhead claims.

North Korea says the missile can carry a heavy nuclear warhead. It also claims to have perfected the warhead's homing and detonation systems under difficult reentry circumstances.

As with much of North Korea's secretive arms program, this couldn't be independently confirmed.

But experts have long believed that manufacturing a compact warhead for a long-range missile capable of striking the US is one of the last remaining technologies North Korea has yet to master.

Some experts say the missile's claimed ability to carry heavy warheads would allow North Korea to deploy larger bombs or multiple warheads potentially capable of striking different targets.

The reentry vehicle

There's also skepticism about North Korea's claims about its reentry technology, which is needed to return a warhead to the atmosphere from space so it can hit its intended target.

Despite North Korea's claim that Sunday's test simulated a reentry situation, South Korean defense officials say the North probably has yet to master the technology.

"There is enormous pressure when a missile reenters the atmosphere ... If (electrical) circuits break and a trigger device fails to detonate nuclear fuel, you can imagine that only some twisted metal will fall on Alaska or Hawaii, even if North Korea fires missiles at them," said Kim Dong-yub, an analyst at Seoul's Institute for Far Eastern Studies.

Another important point: One test, even a successful one, does not prove a missile's capabilities.

A reliable missile must endure at least 10 successful test launches, according to professor Chae Yeon-seok at South Korea's University of Science & Technology.

North Korea said on Monday it had successfully conducted a mid- to-long-range missile test and would continue such launches "any time, any place", defying UN Security Council resolutions and warnings from the United States.

North Korea, which regularly threatens to destroy the United States in a sea of flames, has accused Washington of pushing the Korean peninsula to the brink of nuclear war with recent military drills with South Korea and Japan.

The North's KCNA news agency said Sunday's test launch verified the homing feature of the warhead that allowed it to survive "under the worst re-entry situation" and accurately detonate.

It also tested the North's capability to carry a "large-size heavy nuclear warhead", KCNA said.

"The test-fire proved to the full all the technical specifications of the rocket ... like guidance and stabilization systems ... and reconfirmed the reliability of new rocket engine under the practical flight circumstances," KCNA said.

The test "represents a level of performance never before seen from a North Korean missile", John Schilling, an aerospace expert, said in an analysis on the U.S.-based 38 North website.

"It appears to have not only demonstrated an intermediate-range ballistic missile that might enable them to reliably strike the U.S. base at Guam, but more importantly, may represent a substantial advance to developing an intercontinental ballistic missile."

The missile flew 787 km (489 miles) on a trajectory reaching an altitude of 2,111.5 km (1,312 miles), KCNA said.

North Korea has been developing a long-range missile capable of striking the mainland United States mounted with a nuclear warhead. That would require a flight of 8,000 km (4,800 miles) or more and technology to ensure a warhead's stable re-entry into the atmosphere.

"The test-firing of ICBMs will occur at any time and place, at the will of North Korea's highest leadership," North Korea's ambassador to China, Ji Jae Ryong, told reporters in Beijing on Monday, a day before the UN Security Council meets in New York to discuss the test.

North Korea has defied calls to curb its missile and nuclear weapons programs, testing its relationship with its lone major ally, China, which has always called for talks to resolve the issue, and prompting South Korea's new president, Moon Jae-in, to "strongly condemn" Sunday's action.

"Harmful and dangerous"

U.S. President Donald Trump warned in an interview with Reuters this month that a "major, major conflict" with North Korea was possible. In a show of force, the United States sent an aircraft carrier strike group, led by the USS Carl Vinson, to waters off the Korean peninsula to conduct drills with South Korea and Japan.

It says the "era of strategic patience" with North Korea is over.

Russian President Vladimir Putin said in Beijing that Moscow was opposed to any new countries acquiring nuclear weapons, but that the world should talk to North Korea rather than threaten it.

"I want to confirm that we are categorically against the expansion of the club of nuclear powers, including with the Korean peninsula and North Korea," said Putin, who said any such move would be "harmful and dangerous".

"But at the same time, we understand that what we have observed in the world recently, and specifically flagrant violations of international law and incursions into the territory of foreign states, changes in regime, lead to such kinds of arms races."

Putin did not specify what countries he had in mind, but he has in the past repeatedly criticized the United States for military operations in Iraq, Libya and Syria, and accused it of trying to oust legitimate governments.

The Russian Defence Ministry said on Sunday that the missile crashed into the Sea of Japan around 500 km (310 miles) off the Russian coast.

The North has successfully launched long-range rockets twice to put objects into space. But many had believed it was some years away from mastering re-entry expertise for perfecting an ICBM, which uses similar engineering in early flight stages.

North Korea's official Rodong Sinmun newspaper devoted half of its six-page Monday edition to coverage of the missile test, with vivid color photographs of the launch and jubilant leader Kim Jong Un celebrating with military officers.

The pictures featured a long nose-coned projectile that appeared to be similar to missiles displayed during an April 15 military parade for the birth anniversary of state founder Kim Il Sung, the current leader's grandfather.

The nose cone resembles that of the KN-08 ICBM the North is believed to be developing, and the lofted trajectory tests re-entry by putting the missile through extra stress, said Joshua Pollack of the U.S.-based Non-proliferation Review.

"This is an advanced missile, if their claims are true."

KCNA said Kim accused the United States of "browbeating" countries that "have no nukes", warning Washington not to misjudge the reality that its mainland is in the North's "sighting range for strike".

The United States called the missile launch a message to South Korea, days after Moon took office pledging to engage Pyongyang in dialogue and keep up international pressure to impede the North's arms pursuit.

Two senior national security advisers to Trump will meet Moon's top foreign policy adviser, Chung Eui-yong, in Seoul on Tuesday to discuss a summit of the leaders and the North's missile test, a source with direct knowledge of the meeting said.
