S Korean nuclear envoy to visit US

South Korea said its top nuclear envoy will visit the United States on Wednesday to discuss ways to revive talks on North Koreas nuclear disarmament after the death of leader Kim Jong-Il.Lim Sung-Nam will meet Glyn Davies, the US special representative for North Korea policy, during the two-day trip to Washington through Thursday, South Korean foreign ministry spokesman Cho Byung-Jae told reporters.The two nations, through this meeting, will share opinions on the current state of the Korean Peninsula after Kim Jong-Ils death and discuss coordination to make progress on the Norths nuclear issue, Cho said.Lim met with Chinas chief nuclear envoy Wu Dawei in Beijing last week to discuss how to respond to the sudden demise of North Koreas longtime ruler on December 17.The six-party talks on the Norths nuclear weapons programme -- chaired by China and involving the two Koreas, the United States, Japan and Russia -- have been at a standstill since the last round in December 2008.The North stormed out in April 2009 in protest against what it described as US hostility, and staged its second nuclear test about a month later.The North and China have expressed a wish to return to the forum without precondition. But Washington and Seoul have insisted the North should show sincerity in denuclearisation and ease tensions with the South.Negotiations to resume the talks had appeared to be making progress before Kims death, with reports Pyongyang would agree to suspend its uranium enrichment programme in return for food aid from Washington.Suspending the uranium programme -- seen as a potential source of bomb-making fuel -- is a key US demand before six-party negotiations resume.
