China on Friday backed a U.S.-South Korean proposal aimed at luring North Korea back to long-stalled international talks on its nuclear program. Chinese Vice Foreign Minister Wu Dawei met with top South Korean officials in Seoul as part of renewed efforts to restart the six-party nuclear talks after nearly a year of deadlock. The negotiations, involving China, Japan, the two Koreas, Russia and the United States, last convened in November. Wu's meetings focused on a joint strategy that South Korean President Roh Moo-hyun and U.S. President George W. Bush agreed to pursue at a summit earlier this month. Roh said Thursday that the strategy was outlined to North Korea, but it hasn't given any response so far. Roh declined to give any details of what was contained in the proposal. «I support it,» Wu said Friday after his meetings, the Associated Press reported.
