South Korea's nuclear envoy said Tuesday that he expects the six-party talks on North Korea's nuclear program to resume by mid-December. North Korea agreed earlier this month to return to the negotiations with China, Japan, South Korea, Russia and the United States after staying away from the talks for a year. A specific date of resuming the talks has yet to be set. The need for reopening the negotiations took on added urgency after the North's first-ever nuclear test on Oct. 9. "I think it's possible to resume (the talks) by mid-December," said Chun Yung-woo, Seoul's chief negotiator to the talks, on South Korean radio channel PBC. Chun didn't give a reason why, and couldn't be immediately reached for comment.
