North Korea nuclear envoy leaves talks in Beijing

North Korean chief nuclear envoy Kim Kye Gwan went to Beijing's airport Thursday for a flight home after a breakdown in talks on disarming Pyongyang's nuclear program. Kim had refused to take part in the six-party talks, held this week, on ways to push forward a February agreement on North Korea giving up its nuclear program in return for energy aid because of problems over the transfer of North Korean funds frozen in a Macau bank. Kim waved to reporters when he arrived at the airport but did not say anything.
