South Korea ? Top nuclear envoys from South Korea and the United States held talks Saturday on a strategy to bring North Korea back to disarmament talks, a day after the North claimed it is in the final stages of enriching uranium.

U.S. special envoy on North Korea, Stephen Bosworth, and South Korean envoy Wi Sung-lac made no comments after their meeting.

Bosworth later met with South Korea’s minister in charge of relations with North Korea, and the Unification Ministry said the two agreed to closely cooperate in resolving the nuclear dispute.
