The chief nuclear envoys for North and South Korea met in Beijing to try to revive international nuclear disarmament talks today, with little hope of any early breakthroughs. The one-day meeting in Beijing is the second round of talks between the South's Wi Sung-Lac and his North Korean counterpart Ri Yong-Ho in two months. They aim to pave the way for a resumption of full six-party negotiations on the North's nuclear disarmament, a process which began back in 2003 and groups the two Koreas, China, the United States, Japan and Russia.
