The U.S. and North Korean envoys to six-nation talks on the North's nuclear program held a rare one-on-one meeting Monday on the eve of the talks, the American Embassy said. Details of the U.S.-North Korean meeting weren't immediately released, The Associated Press reported. But the U.S. envoy, Assistant Secretary of State Christopher Hill, said earlier the two sides were "just trying to get acquainted, review how we see things coming up and compare notes." South Korean Deputy Foreign Minister Song Min-soon and his North Korean counterpart, Kim Kye Gwan, met Sunday and "agreed to come up with a framework to realize denuclearization of the Korean Peninsula," a South Korean Foreign Ministry spokesman said. The two Koreas agreed to hold bilateral meetings throughout the talks, the South Korean news agency Yonhap reported.
