Negotiations on North Korea's nuclear program will resume this week for the first time in nine months, South Korea's nuclear envoy said Tuesday. The talks have been on hold since October due to a dispute over North Korea's obligation to declare its nuclear programs. Host China plans to announce soon that the talks will resume Thursday, Seoul's chief nuclear negotiator Kim Sook said before he left for the Chinese capital for preparatory meetings. The six-nation talks - which include China, Japan, Russia, the US and the two Koreas - are back on after Pyongyang submitted a partial declaration of its nuclear programs and made progress in disabling its main atomic facility. The talks were expected to focus on how to verify the North's nuclear list.
