South Korea\'s chief nuclear envoy, Lim Sung-nam, left for Austria Sunday to meet with the U.S. envoy on North Korea to discuss reopening talks. Negotiations between the two Koreas, the United States, China, Russia and Japan were halted in April 2009 when the North left the table and conducted a nuclear test one month later. North Korea and the United States had a meeting in Geneva last month aimed at restarting the six-nation talks on the North\'s nuclear ambitions, the Yonhap News Agency reported Sunday. Lim and U.S. envoy to North Korea Glyn Davies \"will assess the developments related with the North Korean nuclear issue in the wake of the second round of U.S.-North Korea talks held in Geneva and exchange views in this regard,\" South Korea ministry spokesman Cho Byung-jae said. Lim will meet with his Japanese counterpart Shinsuke Sugiyama and Kurt Campbell, assistant U.S. secretary of state for East Asian and Pacific affairs, later this week in Bali, Indonesia, to take part in trilateral talks on the North Korean nuclear standoff. These talks will take place alongside the 18-nation East Asia Summit, Yonhap reported.
