SEOUL - Lim Sung-nam, the Republic of Korea's (ROK) top nuclear envoy to the Six-Party Talks, left for the United States on Wednesday to discuss the situation on the Korean peninsula after the death of Kim Jong-il, the late leader of the Democratic People's Republic of Korea.

During his two-day trip, Lim will hold talks with his US counterpart Glyn Davies, the US special representative on DPRK policy, ROK's Foreign Ministry said.

The two will discuss the aftermath of Kim Jong-il's death, as well as ways for South Korea and the United States to cooperate in efforts toward bringing progress to issues regarding DPRK's nuclear program, the ministry said.

Lim's visit to the United States follows a trip he made to China last week, during which he met his counterpart Wu Dawei and agreed to closely work together in reviving the Six-Party Talks.

The Six-Party nuclear talks, which involve the ROK, the DPRK, China, Japan, Russia and the United States, have been stalled since the last session ended in late 2008.
