North Korea said yesterday it would revive a mothballed nuclear reactor able to produce bomb-grade plutonium but stressed it was seeking a deterrent capacity and did not repeat recent threats to attack South Korea and the United States.

United Nations Secretary-General Ban Ki-moon said the crisis over North Korea had gone too far

United Nations Secretary-General Ban Ki-moon said the crisis over North Korea had gone too far and he appealed for dialogue and negotiation to resolve the situation.

“Nuclear threats are not a game. Aggressive rhetoric and military posturing only result in counter-actions, and fuel fear and instability,” Ban, a South Korean, told a news conference during a visit to Andorra.

The crisis flared after Pyongyang was hit with US sanctions for conducting a third nuclear test in February and the United States and South Korea staged military drills that North Korea viewed as “hostile”.

Pyongyang then threatened a nuclear strike on the United States, missile strikes on its Pacific bases and war with South Korea, prompting Washington to bolster forces in the region. The state-owned KCNA news agency announced yesterday that North Korea would relaunch all nuclear facilities for both electricity and military uses.

One of the most isolated and unpredictable states in the world, North Korea carried out its third nuclear test since 2006 but is seen as some years away from producing a deliverable nuclear weapon, although it claims to have a deterrent.

A speech by the North’s young leader, Kim Jong-un, given on Sunday but published in full by KCNA yesterday, appeared to dampen any prospect of a direct confrontation with the United States by emphasising that nuclear weapons would ensure the country’s safety as a deterrent.

“Our nuclear strength is a reliable war deterrent and a guarantee to protect our sovereignty,” Kim said. “It is on the basis of a strong nuclear strength that peace and prosperity can exist and so can the happiness of people’s lives.” Kim’s speech, delivered to the central committee meeting of the ruling Workers Party of Korea, hinted at a small shift away from threats against Seoul and Washington, but it remained some distance from calling any kind of end to the crisis.

“The fact that this (speech) was made at the party central committee meeting, which is the highest policy-setting organ, indicates an attempt to highlight economic problems and shift the focus from security to the economy,” said Yang Moo-jin of the University of North Korean Studies in Seoul.

But if Pyongyang indeed restarts the nuclear facilities, it would have longer-term implications for the region’s security.

Reactivating the aged Soviet-era reactor at the Yongbyon nuclear plant would yield plutonium, a tested path to stockpile more fissile material than a uranium enrichment programme.

It was unclear how quickly Yongbyon, whose cooling tower was destroyed as part of an earlier de-nuclearisation deal with major powers, would take to restart.

It was also impossible to verify whether Yongbyon remained connected to North Korea‘s antiquated electricity grid at all.

“It was a reactor that was nearing obsolescence with a cooling tower that wasn’t functioning properly when it was blown up. It could mean they’ve been rebuilding quite a few things,” said Yoo Ho-yeol, North Korea specialist at Korea University in Seoul.

The move to restart the reactor undermines China’s stated aim of restarting de-nuclearisation talks on the Korean peninsula, prompting a foreign ministry spokesman in Beijing to express regret at the decision.

The United Nations secretary-general said “things must calm down as this situation, made worse by the lack of communication, could lead down a path that nobody should want to follow”.

Ban offered to help the parties to begin talks. “I am convinced that nobody intends to attack (North Korea) because of disagreements about its political system or foreign policy. However, I am afraid that others will respond firmly to any direct military provocation,” he said.

As well as reviving the 5MW reactor at Yongbyon, the North’s only known source of plutonium for its nuclear programme, KCNA said a uranium enrichment plant would also be put back into operation.

The nuclear plant’s output would be used to solve what KCNA termed an “acute shortage of electricity” and to bolster “the nuclear armed force”.
