South Korea’s top nuclear envoy left for China Thursday to discuss the recent situation in North Korea, with satellite images suggesting that the North could launch a long-range missile in coming weeks. Lim Sung-nam, Seoul’s chief negotiator to six-party talks aimed at ending the North’s nuclear ambitions, will meet with his Chinese counterpart Wu Dawei and other Beijing officials during his two-day trip, according to South Korea’s (Yonhap) News Agency. Lim will exchange views on the recent situation on the Korean Peninsula with Chinese officials. Lim and Chinese officials will also “exchange views on the direction of the North Korea policy under the new Chinese leadership and discuss future cooperation over issues on the Korean Peninsula,” the envoy said.
