Japan, South Korea sign preliminary intelligence-sharing pact on North Korea

TOKYO (Reuters) – Japan and South Korea signed a preliminary pact to share and safeguard sensitive information on North Korea’s missile and nuclear activities on Monday, a move that had already prompted anger among opposition lawmakers in Seoul.

The signing of the General Security of Military Information Agreement had originally been expected in 2012, but South Korea postponed it amid domestic opposition against concluding such a security pact with Japan, a one-time colonial ruler.

Japan’s Foreign Ministry said in a statement that discussions in the third round of the talks had reached an agreement and that a provisional signing had taken place.

Discussions would continue ahead of a final signing, which Kyodo news agency said could take place by the end of November.

Reclusive North Korea, which is still technically at war with the South because their 1950-53 conflict ended in a truce, not a peace treaty, has carried out repeated nuclear and missile tests in defiance of U.N. Security Council resolutions and sanctions.

Tokyo’s ties with Seoul, plagued by a territorial dispute and Japan’s past military aggression, have warmed after reaching a landmark agreement last December to resolve the issue of Korean girls and women forced to work in Japan’s wartime brothels.

South Korean opposition parties had warned against signing the agreement, threatening to dismiss or impeach Defence Minister Han Min-koo.

Duterte, Philippines could join sea exercises with Japan, vents anger at U.S.

By Minami Funakoshi

YOKOHAMA, Japan (Reuters) – Philippine President Rodrigo Duterte said on Thursday his country could join naval exercises with Japan, but repeated there would be no more war games with long-time ally the United States and again gave vent to his anger against Washington.

Duterte also said he had explained to Japanese Prime Minister Shinzo Abe in talks on Wednesday just why he resented the United States, reiterating that Washington treated the Philippines like “dogs on a leash” and lectured about human rights in connection with his domestic campaign against drugs.

The Philippine leader’s visit to Japan coincides with jitters about his foreign policy after weeks of verbal attacks on the United States, including threats to end military agreements, and overtures toward China.

Duterte last week announced in China his “separation” from the United States, but then insisted ties were not being severed and that he was merely pursuing an independent foreign policy.

“Joint exercise with Japan in general terms is not a problem. Stationing of Japanese troops was not discussed and with the Americans, it’s problematic,” Duterte told reporters one day after saying he wanted foreign troops out of his country “maybe in the next two years”.

“I don’t want to embarrass my defense secretary but the exercises with the Americans will be the last,” he said.

Duterte, on the final day of a three-day visit to Japan, made the comments after watching Japan Coast Guard activities in the port of Yokohama, near Tokyo.

Duterte’s recent comments pose a headache for Abe, who has tightened ties with Washington while building closer security relations with Manila and other Southeast Asian countries as a counter-weight to a rising China, which has maritime feuds with several countries in the region including Japan.

In their Wednesday talks, Duterte and Abe agreed on the importance of settling maritime disputes peacefully.

Duterte said he had explained to Abe why he was angry with the United States.

“I had told the prime minister some of my sentiments against the Americans. They are treating us like dogs on a leash,” he said. “The prime minister understands that.”

Domestic backing for Duterte is strong, but there is far from the same level of support for his stance on the United States. A peaceful protest outside the U.S. embassy in Manila in support of Duterte on Thursday drew about 500 people.

While Duterte’s anti-U.S. diatribes cast doubts on the future of the U.S.-Philippine security alliance, a clearer picture could emerge next month when defense officials from both sides have a meeting in Manila that takes place annually and typically plans joint exercises for the following year.

Although Duterte said there would be no more joint exercises, an army spokesman on Thursday confirmed preparations were under way for drills next month on the island of Palawan involving Filipino troops and a small unit of U.S. special forces.

“This was planned more than a year ago, but if there will be an order from higher authorities to cancel it, we will obey,” Colonel Benjamin Hao, an army spokesman, said.

“But, so far, there are no instructions.”

A scheduled call by Duterte on Japanese Emperor Akihito, 82, was canceled following the death on Thursday of Akihito’s 100-year-old uncle, Prince Mikasa.

Despite failures, North Korea could field missile next year: U.S. expert

A test-fire of strategic submarine-launched ballistic missile is seen in this undated photo released by North Korea's Korean Central News Agency

By David Brunnstrom

WASHINGTON (Reuters) – In spite of the apparent failure of another North Korean missile test at the weekend, the country’s aggressive testing schedule could see its Musudan intermediate ballistic missile entering operational service sometime next year – much sooner than expected, a leading U.S. expert said on Monday.

The U.S. military said on Saturday it had detected a failed launch of a Musudan, the latest in a series in violation of United Nations resolutions.

The U.S. Strategic Command said the missile failed in a launch near North Korea’s northwestern city of Kusong. South Korea’s military said the missile failed immediately after launch, but neither it nor the Pentagon suggested reasons.

The Musudan has range of some 3,000 km (1,860 miles), posing a threat to South Korea and Japan, and possibly the U.S. territory of Guam. Pyongyang claims that it has succeeded in miniaturizing a nuclear warhead that can be mounted on a missile, but this have never been independently verified.

John Schilling, an aerospace engineer specializing in rocket propulsion, said it was noteworthy that North Korea had launched the missile from its west coast, rather than from its purpose-built test facility.

“Moving to a roadside near Kusong is like taking the training wheels off the bicycle, seeing if you really have mastered something new,” he wrote on the 38 North website that monitors North Korea.

Schilling said the move showed that in spite of only one successful launch to show for seven attempts this year, North Korea was not simply repeating old failures.

“They are continuing with an aggressive test schedule that involves, at least this time, demonstrating new operational capabilities. That increases the probability of individual tests failing, but it means they will learn more with each test,” he wrote.

“If they continue at this rate, the Musudan intermediate -range ballistic missile could enter operational service sometime next year – much sooner than had previously been expected,” Schilling said

The latest test comes ahead of a meeting on Wednesday in Washington of U.S., Japanese and South Korean defense and foreign ministers expected to focus on North Korea’s missile and nuclear programs.

The top U.S. diplomat for East Asia said last month Washington would speed up deployment of the U.S. Terminal High Altitude Area Defense (THAAD) anti-missile system to South Korea given the pace of North Korea’s missile tests.

Japanese government sources told Reuters Japan may accelerate around $1 billion of planned spending to upgrade its ballistic missile defenses.

Japan may accelerate missile defense upgrades in wake of North Korean tests

TOKYO (Reuters) – Japan may accelerate around $1 billion of planned spending to upgrade its ballistic missile defenses in the wake of rocket tests suggesting North Korea is close to fielding a more potent medium-range missile, three government sources told Reuters.

The outlays, currently in a budget request for the year starting April, includes money to assess a new missile defense layer – either Lockheed Martin Corp’s Terminal High Altitude Area Defence (THAAD) system or Aegis Ashore, a land-based version of the ballistic missile defense system used by vessels in the Sea of Japan.

It also covers money to improve the range and accuracy of PAC-3 Patriot batteries, said the sources familiar with the proposal, who asked not to be identified because they are not authorized to talk to the media.

Any rollout of THAAD or Aegis Ashore could, however, still take years, the sources noted. Accelerated spending on Patriot missile batteries is also unlikely to deliver upgrades much quicker because of the limited capacity of the companies involved – Mitsubishi Heavy Industries and Raytheon Co to speed up already tight production schedules.

“It nonetheless has symbolic value,” said one of the sources.

As much as 300 billion yen ($2.9 billion) of defense funding will be included in a third supplementary budget, the Sankei newspaper reported earlier. Prime Minister Shinzo Abe’s government has yet to say whether it will ask lawmakers to approve additional outlays before deliberations begin on next year’s budget.

Officials at Japan’s Ministry of Defence were not immediately available to comment.

ARMS RACE

Pyongyang’s apparent technological progress on missiles has been faster than anticipated, exposing Japan to a heightened threat, a senior Japanese military commander told Reuters earlier this month.

Tokyo and Pyongyang have been locked in an arms race for two decades after North Korea fired a missile over Japan in 1998.

North Korea has test fired at least 21 ballistic missiles and conducted two nuclear tests so far this year. On June 22, a medium range Musudan rocket reached an altitude of 1,000 km (620 miles) on a lofted trajectory, potentially beyond the range of Aegis destroyers the Sea of Japan that are armed with SM-3 missiles designed to hit warheads at the edge of space.

That leaves older PAC-3 Patriot missiles protecting major cities including Tokyo as a last line of defense. Their upgrade program will not deliver the first improved batteries until the 2020, in time for the Tokyo Olympics.

Warheads from missiles such as Pyongyang’s Rodong, with an estimated range of 1,300 km (810 miles), travel at speeds of up to 3 km (2 miles) a second. Payloads on rockets like the Musudan, that can fly as far as 3,000 km (1,860 miles), plunge from space at least twice as fast.

Japan next year plans to acquire a more powerful version of the SM-3 it is jointly developing with the United States, dubbed the Block IIA. It has not, however, said when the first will be deployed.

China armed forces warn Japan against South China sea patrols

Chinese and Japanese warships

BEIJING, Sept 29 (Reuters) – Japan is “playing with fire” with plans to step up activity in the contested South China Sea through joint training patrols with the United States, China’s Defence Ministry said on Thursday, warning it would not sit watching from the sidelines.

China claims virtually the entire South China Sea and has repeatedly denounced what it views as interference there by the United States and its ally, Japan.

Japan is strengthening its ties in the region, in particular with the Philippines and Vietnam, which contest China’s claims to parts of the sea, and it aims to help build the capacity of coastal states in the busy waterway, its defence minister said this month during a visit to Washington.

Chinese Defence Ministry spokesman Yang Yujun, asked about Japan’s plans, said it had constantly been trying to stir things up in the South China Sea for its own purposes.

“We must solemnly tell Japan this is a miscalculation. If Japan wants to have joint patrols or drills in waters under Chinese jurisdiction this really is playing with fire,” Yang told a monthly news briefing.

“China’s military will not sit idly by,” he added, without elaborating.

Ties between Asia’s two largest economies have long been overshadowed by arguments over their painful wartime history and a territorial spat in the East China Sea, among other issues.

Ships carrying about $5 trillion in trade pass through the South China Sea every year.

Brunei, Malaysia and Taiwan also have claims in the sea, which is also believed to be rich in energy resources and fish stocks.

In July, an arbitration court in the Hague said China’s claims to the waterway were invalid, after a case was brought by the Philippines. China has refused to recognise the ruling.

Top diplomats from U.S., Japan, South Korea to meet on North Korea

By Tony Munroe and Ben Blanchard

SEOUL/BEIJING, Sept 14 (Reuters) – U.S. Secretary of State John Kerry will meet with his Japanese and South Korean counterparts in New York on Sunday to discuss responses to North Korea’s latest nuclear test, South Korea’s foreign ministry said on Wednesday.

The three countries are pushing for tough new U.N. Security Council sanctions on North Korea after the isolated country on Friday conducted its fifth and largest nuclear test.

The blast was in defiance of U.N. sanctions that were tightened in March.

China, the North’s chief ally, backed the March resolution but is more resistant to harsh new sanctions this time after the United States and South Korea decided to deploy a sophisticated anti-missile system in the South, which China adamantly opposes.

South Korea said Foreign Minister Yun Byung-se and his counterparts Kerry and Japanese Foreign Minister Fumio Kishida will meet during the annual U.N. General Assembly to discuss putting further pressure on North Korea.

The United States wants China to do more, with U.S. Defense Secretary Ash Carter last week singling out the role he said China should play in curbing its neighbor.

TESTING TIMES

North Korea has been testing nuclear weapons and ballistic missiles at an unprecedented rate this year under young leader Kim Jong Un.

On Tuesday, Chinese Foreign Minister Wang Yi spoke with South Korea’s Yun by phone, expressing Beijing’s opposition to the North’s latest nuclear test but also reiterating opposition to the planned deployment of the Terminal High Altitude Area Defense (THADD) anti-missile system in the South, China’s foreign ministry said.

China is North Korea’s most important diplomatic and trade partner and refuses to cut the country off completely, fearing it could collapse.

Beijing’s official People’s Daily newspaper on Wednesday called the United States a troublemaker and said it has no right to lecture China about taking responsibility for reining in North Korea as tensions on the peninsula are a direct result of U.S. actions.

In a commentary, the ruling Communist Party’s official paper said the United States was pretending it had nothing to do with the North Korea issue and was putting the blame on others.

“People have reason to doubt whether Washington is willing to make the effort to push the North Korea issue in the direction of a resolution,” the paper said.

China and Russia have pushed for a resumption of six party talks on denuclearization in North Korea. The talks, which also involve Japan, South Korea and the United States, have been on hold since 2008.

Washington has said it is willing to negotiate with the North if it the country commits to denuclearization, which Pyongyang has refused to do.

Japanese Prime Minister Shinzo Abe will seek Cuba’s help in responding to North Korea’s nuclear and missile programs during a rare visit to Havana next week, a spokesman said.

Asia leaders tiptoe around South China Sea tensions

Asian leaders

By Amy Sawitta Lefevre and Manuel Mogato

VIENTIANE, Sept 8 (Reuters) – Asian leaders played down
tensions over the South China Sea in a carefully worded summit
statement on Thursday, but even before it was issued Beijing
voiced frustration with countries outside the region
“interfering” in tussles over the strategic waterway.

The heads of 10 Southeast Asian nations, as well as U.S.
President Barack Obama and Chinese Premier Li Keqiang among six
other leaders, “reaffirmed the importance of maintaining peace,
stability, security and freedom of navigation in and over-flight
in the South China Sea.”

But the draft of a statement to be issued in Vientiane,
Laos, tiptoed around the regional strains caused by competing
claims to areas of the strategically important sea.

“Several leaders remained seriously concerned over recent
developments in the South China Sea,” said the draft.

The statement, seen by Reuters, made no reference to a July
ruling by a court in The Hague that declared illegal some of
China’s artificial islands in the sea and invalidated its claims
to almost the entire waterway.

Obama said on Thursday the ruling had helped clarify
maritime rights. “I recognize this raises tensions but I also
look forward to discussing how we can constructively move
forward together to lower tensions,” he said at a summit
meeting.

Officials said that talks on Wednesday between leaders of
the Association of Southeast Asian Nations (ASEAN) and China’s
Li had gone smoothly.

But in a statement later from China’s Foreign Ministry, Li
was paraphrased as saying China was willing to work with
Southeast Asian countries in “dispelling interference … and
properly handling the South China Sea issue.”

He did not elaborate, but such wording is typically used by
Chinese leaders to refer to not allowing countries from outside
the region with no direct involvement in the dispute, like the
United States, from getting involved.

China claims much of the South China Sea, through which more
than $5 trillion of trade moves annually. Taiwan and four ASEAN
members – Vietnam, the Philippines, Malaysia and Brunei – also
have claims, making it a hot spot of regional tension.

The other ASEAN nations are Cambodia, Indonesia, Laos,
Myanmar, Singapore and Thailand. Leaders from Australia, China,
India, Japan, New Zealand, Russia, South Korea and the United
States also attended the summit.

China has over the past year alarmed other claimants, and
outside powers such as the United States and Japan, by
re-claiming land on several disputed reefs through dredging, and
building air fields and port facilities.

Shattering an illusion of cordiality at the summit in Laos
on Wednesday, U.S. ally the Philippines released photographs and
a map showing what it said was an increased number of Chinese
vessels near the disputed Scarborough Shoal, which China seized
after a standoff in 2012.

Its defense ministry expressed “grave concern” that Chinese
boats were preparing to build structures at the shoal.

CLEARED THE AIR

The Philippines’ move came after a dispute with the United
States, its former colonial power. Ties turned frosty when new
President Rodrigo Duterte insulted U.S. counterpart Barack Obama
on Monday, prompting the cancellation of a meeting between them.

The two leaders made some steps towards clearing the air
late on Wednesday, however, chatting briefly, and exchanging
pleasantries as they prepared to take their seats at a leaders’
dinner.

The United States has been a staunch ally of the Philippines
and China has repeatedly blamed Washington for stirring up
trouble in the South China Sea.

Washington says it has no position on the territorial
disputes but wants to ensure freedom of navigation. To press
that point, it has conducted patrols near Chinese-held islands.

Although the Scarborough Shoal is merely a few rocks poking
above the sea, it is important to the Philippines because of the
fish stocks in the area. Manila says China’s blockade of the
shoal is a violation of international law.

The dispute has become more significant since the Permanent
Court of Arbitration ruled in July that no country had sovereign
rights over activity at Scarborough Shoal. China has refused to
recognize the ruling by the court in The Hague.

Li made no direct mention of Scarborough Shoal in the
comments provided by the foreign ministry, but Beijing said on
Wednesday there had been no new activity there and “some people”
were spreading information that was “hyping the situation.”

China’s embassy in Manila said there has been no dredging or
building at the shoal and China has maintained a coastguard
presence there for law enforcement patrols.

A statement by ASEAN on Wednesday listed eight points
related to the South China Sea, but made no mention of the
arbitration ruling.

The bloc traditionally shies away from taking a position on
thorny diplomatic issues, especially where China is concerned,
because of its influence in the region and the need to balance
ties with the United States.

“Both China and the United States are among the most
important partners of ASEAN, and ASEAN does not want to have to
choose between those partners,” the secretary general of the
bloc, Le Luong Minh, told Reuters in an interview on Thursday.

North Korea’s Kim declares sub missile launch ‘greatest success’

North Korean leader Kim Jong Un is pictured during a test-fire of strategic submarine-launched ballistic missile

By Jack Kim

SEOUL (Reuters) – North Korean leader Kim Jong Un supervised the test-firing of a submarine-launched ballistic missile and declared it “the greatest success,” which puts the country in the “front rank” of nuclear military powers, official media reported on Thursday.

North Korea fired a submarine-launched ballistic missile (SLBM) on Wednesday which flew about 500 km (300 miles) towards Japan. The South Korean government and experts said the launch showed technical progress in the North’s SLBM program.

“A test-fire of strategic submarine-launched ballistic missile was successfully conducted under the guidance of supreme commander of the Korean People’s Army Kim Jong Un,” the North’s official KCNA news agency said.

“He appreciated the test-fire as the greatest success and victory,” KCNA said.

“He noted with pride that the results of the test-fire proved in actuality that the DPRK joined the front rank of the military powers fully equipped with nuclear attack capability.”

DPRK, the Democratic People’s Republic of Korea, is North Korea’s formal name.

North Korea has conducted a spate of military technology tests this year, including a fourth nuclear test in January and numerous ballistic missile launches, in defiance of U.N. Security Council sanctions that were tightened in March.

North Korea said this year it had miniaturized a nuclear warhead to fit on a ballistic missile but outside experts have said there is yet no firm evidence to back up that claim or show it had mastered the technology to bring a live warhead back into the atmosphere and guide it to strike a target.

North Korean state television on Thursday showed video clips of the launch of a missile from underwater at dawn, and still photographs of Kim on the dock at a port as a large crane unloaded an object onto a submarine.

Kim is also seen jubilantly celebrating with military aides in photographs carried by the official Rodong Sinmun newspaper.

REACHED JAPAN DEFENCE ZONE

The Washington-based 38 North project said in a report that the missile was launched from the North’s sole experimental missile submarine and a satellite photograph taken on Monday showed final preparations, likely after the missile had already been loaded onto the submarine using a heavy construction crane.

The test showed the solid-fuel missile’s control and guidance system as well as the atmospheric re-entry of the warhead all met operational requirements, KCNA said.

The South Korean and U.S. militaries said the missile was fired from near the coastal city of Sinpo, where a submarine base is located. Japan said the missile reached its air defense identification zone, the first time by a North Korean missile.

The UN Security Council met behind closed doors on Wednesday at the request of the United States and Japan to discuss the launch. Deputy Russian U.N. Ambassador Petr Iliichev said the United States would circulate a draft press statement.

The meeting comes after the Security Council was unable to condemn a missile launch by the North earlier this month that landed near Japan because China wanted the statement to also oppose the planned deployment of a U.S. missile defense system in South Korea.

China said on Wednesday that it opposes the North’s nuclear and missile programs. It had been angered by what it views as provocative moves by the United States and South Korea on the decision to deploy the THAAD (Terminal High Altitude Area Defence) anti-missile system in South Korea.

North Korea fires submarine launched ballistic missile

North Korean leader Kim Jong Un guides on the spot the underwater test-fire of strategic submarine ballistic missile

By Ju-min Park and Jack Kim

SEOUL (Reuters) – North Korea fired a submarine-launched missile on Wednesday that flew about 500 km (311 miles) towards Japan, a show of improving technological capability for the isolated country that has conducted a series of launches in defiance of UN sanctions.

Having the ability to fire a missile from a submarine could help North Korea evade a new anti-missile system planned for South Korea and pose a threat even if nuclear-armed North Korea’s land-based arsenal was destroyed, experts said.

The ballistic missile was fired at around 5:30 a.m. (2030 GMT) from near the coastal city of Sinpo, where a submarine base is located, officials at South Korea’s Joint Chiefs of Staff and the Defence Ministry told Reuters.

The projectile reached Japan’s air defence identification zone (ADIZ) for the first time, Chief Cabinet Secretary Yoshihide Suga told a briefing, referring to an area of control designated by countries to help maintain air security.

The missile was fired at a high angle, South Korea’s Yonhap News Agency reported, an indication that its full range would be 1,000 km (620 miles) at an ordinary trajectory. The distance indicated the North’s push to develop a submarine-launched missile system was paying off, officials and experts said.

North Korea’s “SLBM (submarine-launched ballistic missile) technology appears to have progressed,” a South Korean military official told Reuters.

Jeffrey Lewis of the California-based Middlebury Institute of International Studies said the test appeared to be a success.

“We don’t know the full range, but 500 km is either full range or a full range on a lofted trajectory. Either way, that missile works.”

The launch came two days after rival South Korea and the United States began annual military exercises in the South that North Korea condemns as a preparation for invasion, and has threatened retaliation.

Beijing is Pyongyang’s main ally but has joined past U.N. Security Council resolutions against the North. It has been angered by what it views as provocative moves by the United States and South Korea, including their July decision to base the THAAD (Terminal High Altitude Area Defence) anti-missile system in South Korea.

China opposes North Korea’s nuclear and missile programme as well as any words or deeds that cause tension on the Korean peninsula, its foreign minister, Wang Yi, said on Wednesday at previously scheduled meeting with his Japanese and South Korean counterparts in Tokyo.

South Korea’s Foreign Ministry condemned the launch and warned of more sanctions and isolation for its rival that “will only speed up its self-destruction.”

“This poses a grave threat to Japan’s security, and is an unforgivable act that damages regional peace and stability markedly,” Japanese Prime Minister Shinzo Abe told reporters, adding that Japan had lodged a stern protest.

GROWING ISOLATION

North Korea has become further isolated after a January nuclear test, its fourth, and the launch of a long-range rocket in February which brought tightened UN sanctions.

It has launched numerous missiles of various types this year, including one this month that landed in or near Japanese-controlled waters.

Joshua Pollack, editor of the U.S.-based Nonproliferation Review, said claiming to have mastered SLBM technology is as much about prestige as a military breakthrough, a status enjoyed only by six countries including the United States, Russia and China.

“I think it’s meant foremost as a demonstration of sheer technical capability and a demand for status and respect,” Pollack said.

South Korea believes the North has a fleet of more than 70 aging, limited-range submarines – a mix of Chinese, Russian and locally made boats. Acquiring a fleet of submarines large and quiet enough and with a longer range would be a next step for the North, experts said.

“They keep conducting nuclear tests and SLBMs together which means they are showing they can arm SLBMs with miniaturised nuclear warheads,” said Moon Keun-sik, a retired South Korean navy officer and an expert in submarine warfare.

North Korea said this year it had miniaturized a nuclear warhead to fit on a ballistic missile but outside experts have said there is yet to be firm evidence to back up the claim.

Tensions on the Korean peninsula were exacerbated by the recent defection of North Korea’s deputy ambassador in London to South Korea, an embarrassing setback to the regime of North Korean leader Kim Jong Un.
