SEOUL, Jan. 8 (Xinhua) -- South Korea's top nuclear envoy will visit the United States this week to discuss the Korean Peninsula's nuclear issue, Seoul's foreign ministry said Monday.

Lee Do-hoon, special representative for the Korean Peninsula peace and security affairs, will visit Washington from Wednesday to Friday.

During the visit, Lee will meet with his U.S. counterpart Joseph Yun, a chief negotiator at the six-party talks for the denuclearized Korean Peninsula.

Lee will also meet with key figures of the U.S. government in charge of the Democratic People's Republic of Korea (DPRK) affairs, according to the ministry.

The South Korean envoy will make an in-depth discussion with U.S. officials on ways to peacefully resolve the peninsula's nuclear issue and improve inter-Korean relations.

Lee's visit to Washington would come a day after the high-level talks between South Korea and the DPRK scheduled to be held Tuesday in the truce village of Panmunjom.
