Hwang Joon-Kook, South Korea's chief delegate to the six-party talks, will meet his Chinese counterpart Wu Dawei in Beijing tomorrow, Seoul's foreign ministry said.
The two, picking up where they left off last October, will discuss ways to prevent further North Korean nuclear tests and the possibility of "reactivating denuclearisation talks", said ministry spokesman Noh Kwang-Il.
The Beijing meeting raises the possibility of a new round of diplomacy to revive the six-party talks last held in December 2008, and grouping the two Koreas, host China, Russia, Japan and the United States.
"We want to test if they have an interest in resuming negotiations," it quoted a senior US administration official as saying.

It accused Washington of trying to create the wrong impression that Pyongyang was the main obstacle to dialogue.
