South Korea's leader and U.S. President George W. Bush have agreed to seek an early resumption of stalled six-nation talks aimed at curbing communist North Korea's nuclear weapons programs, President Roh Moo-hyun's office said in a statement Saturday. Bush responded positively to the proposal Roh made during a 10-minute phone conversation late Friday, said the presidential Blue House. The South Korean president had called the American leader to congratulate him on his re-election and reconfirm the U.S.-South Korea alliance. "President Roh suggested that the two heads of state work through close consultations and try to resolve the North Korean nuclear issue as a key project and pave the way for a turning point for peace on the Korean Peninsula and for the rest of the world," the statement said. "The two leaders agreed that South Korea and the United States should make joint efforts to hold a next round of six-nation talks soon," it added.
