The chief nuclear negotiators of South and North Korea met on Friday for the first time since 2008, raising cautious hopes that after months of recriminations the countries are inching toward broader talks on ending the Norths nuclear weapons program. The negotiators, Wi Sung-lac of South Korea and Ri Yong-ho, a newly appointed North Korean envoy to the six-party talks, met on the sidelines of the Association of Southeast Asian Nations regional forum being held in Bali, an Indonesian island, officials in Seoul said. The meeting was the first time that the two Koreas nuclear envoys had sat together since the chief delegates to the six-nation talks met in late 2008. The talks have not resumed since, amid tensions over South Koreas harder line toward the North, United Nations sanctions imposed on the North after it launched a long-range rocket and staged its second nuclear test in 2009, and military actions by the North, including the shelling of a South Korean border island last November.
