South Korea's foreign ministry said Monday that it named a new top envoy to the long-stalled six-party talks on the Korean Peninsula nuclear issue.

Lee Do-hoon, 55, a former presidential secretary for foreign affairs, was named as special representative for Korean Peninsula's peace and security affairs, according to Seoul's foreign ministry.

Lee will represent South Korea in the six-way talks, which involve South Korea, the Democratic People's Republic of Korea (DPRK), China, the United States, Russia and Japan.

The aid-for-disarmament dialogue, initiated in Beijing in August 2003, has been stalled since December 2008.
