China hopes the Republic of Korea (ROK) could cooperate with the International Atomic Energy Agency (IAEA) to solve its nuclear experiment problems, said Chinese Foreign Ministry spokesman Kong Quan on Tuesday.

China received messages from both the ROK and the agency saying that the IAEA had already wrapped up its investigation in ROK, Kong said at a regular press conference.

Kong said China wishes the issue would not hamper the scheduling of the fourth round of six-party talks about the Korean Peninsula nuclear issue. The working group meeting should be held before the end of September.

There have already been three rounds of discussions in Beijing involving China, the Democratic People's Republic of Korea, the United States, the Republic of Korea, Russia and Japan.
