The U.N. Security Council is expected to begin official talks on response measures to the "Cheonan" incident after being briefed on the results of a South Korea-led international investigation early Tuesday morning Korea time.

Immediately following the briefing, Claude Heller, the Mexican Ambassador to the United Nations who is the rotating president of the 15-member council, will lead a closed-door meeting of council representatives known as a “mutual dialogue.”

The council is expected to hold open talks later.

South Korea is reportedly coordinating with key members a message condemning North Korea, be it a resolution or a chairman's statement.

China, a veto-wielding UNSC member, is reportedly opposed to adopting a resolution imposing additional sanctions on North Korea.
