South Korea's top nuclear negotiator was scheduled to meet Chinese officials in Beijing on Monday for talks likely to focus on North Korea's atomic test, Seoul's embassy in Beijing said.
Chun Yung-woo arrived in Beijing for a pre-scheduled day of talks with officials including Wu Dawei, his Chinese counterpart, and he was expected to return home on Tuesday, an embassy official said.
"They will probably discuss how (South) Korea, China and all the other related parties should respond to this nuclear test and what is the most effective way to respond to it," said the official.
Chun is South Korea's chief delegate to six-party talks on North Korea's nuclear program, which have been stalled since late 2005.
The talks involve the two Koreas, China, the United States, Japan and Russia.
The official said that despite the test there was no change so far in plans for South Korean President Roh Moo-Hyun to visit China on Friday.
North Korea announced it had carried out its first nuclear weapons test earlier Monday, calling it a "historic event."
