In unusually harsh language, China has condemned North Korea's test of a nuclear weapon. The official statement tells North Korea it must halt any activities that would worsen the situation.
On 9 October, the Democratic People's Republic of Korea flagrantly conducted a nuclear test in disregard of the common opposition of the international community. The Chinese Government is firmly opposed to this act.
To bring about denuclearization of the Korean Peninsula and oppose nuclear proliferation is the firm and consistent stand of the Chinese Government. China strongly urges the DPRK to honor its commitment to denuclearization, stop all moves that may further worsen the situation and return to the Six-Party Talks.
To safeguard peace and stability in Northeast Asia serves the interests of all parties involved. The Chinese Government calls on all parties concerned to be cool-headed in response and persist in seeking a peaceful solution through consultation and dialogue. China will continue to make every effort towards this goal.
This is a departure from the normal Chinese verbiage in these situations, but still doesn't appear to be very supportive of really putting pressure on Kim to back off, either. We'll have to see how they react in the emergency meeting of the Security Council.
