Despite reports earlier this week that North Korea had been planning three more nuclear tests, there are fresh reports that North Korea is saying there will be no more tests. From the Korea Times:

North Korean leader Kim Jong-il told a ranking Chinese envoy that his country has no plan to conduct additional nuclear tests, the Yonhap News Agency reported on Friday (Oct. 20).

Quoting an unnamed diplomatic source in Seoul, Yonhap said Kim made the promise in his meeting with Chinese State Councilor Tang Jiaxuan, who visited Pyongyang as Chinese President Hu Jintao's special envoy earlier this week.

"Kim was known to have clarified his stance that there will be no additional nuclear test," the South Korean news agency quoted the source as saying.

It said that if Kim's position is confirmed to be true, it will raise hopes for the resumption of the six-party talks on Pyongyang's nuclear program and defuse the tension escalated by North Korea's detonation of a nuclear bomb on Oct. 9.

I'd say the answer is "none of the above." I'd have to go with "threats of Chinese economic coercion":

China is weighing tough measures to curb North Korea's nuclear ambitions, with government experts calling for the reduction of critical supplies of oil and food that have helped sustain its isolated, impoverished neighbor.

The options Beijing is considering mark a break from even the recent past in which China has preferred to use incentives rather than threats with Pyongyang. But the Oct. 9 nuclear test further frayed already damaged ties and strengthened the hand of critics who believe Beijing should take a harder line against a country they say has ignored Chinese interests.

On Friday, all four major Chinese state-owned banks and British-owned HSBC Corp. said they have stopped financial transfers to the North - a step beyond what U.N. sanctions require and a likely blow to a weak economy that relies on China as a link to the world financial system.

Even before the nuclear test, with its patience wearing thin, China reduced food aid by two-thirds to the chronically food-short North this year, according to the U.N. World Food Program. After voting last week for the U.N. sanctions that ban trade in military and luxury goods, China stepped up inspections of the trucks crossing into North Korea.

"There's no doubt that China is increasing pressure," said Shi Yinhong, a professor of international relations at Renmin University in Beijing. "If North Korea continues to behave in this way, go down this path, China will be forced to take more severe measures."

Whether the DPRK returns to six-party talks remains to be seen.
