Back here in Seoul,
South Korea and China have agreed to work toward restarting the six-party talks and making progress in denuclearizing North Korea.
The agreement was reached in a meeting between South Korean Foreign Minister Kim Sung-hwan and China's chief nuclear envoy, Wu Dawei, whose trip to Seoul began Tuesday.
During the meeting, the two talked about ways to make progress in improving inter-Korean relations and agreed that Pyeongyang must not provoke Seoul any further.
Wu's visit follows a meeting with his North Korean counterpart, Kim Kye-gwan in Beijing earlier this month, and is the latest in a flurry of diplomatic efforts to deal with North Korea's nuclear programs.
