U.S. Assistant Secretary of State for East Asia and the Pacific, Kurt Campbell, is set to visit Seoul Wednesday to discuss the state of affairs in the Democratic People 's Republic of Korea (DPRK) following its top leader's death.

During his three-day Seoul trip, followed by a China visit, Campbell is scheduled to meet Thursday with Lim Sung-nam, Seoul's chief envoy to the stalled six-party talks aimed at ending the DPRK's nuclear program, according to the foreign ministry.

The two are expected to discuss developments in the DPRK following top leader Kim Jong Il's death last month and ways to resume the six-party negotiations, which also involve China, Japan and Russia.

Campbell will also sit down with South Korean Foreign Minister Kim Sung-hwan later Thursday before leaving for Japan on Friday.

The disarmament-for-aid talks were last held in December 2008. The DPRK unilaterally quit the forum in 2009, but has expressed its wish to return to the negotiating table.
