HONG KONG -- North Korea's nuclear test Oct. 9 may have created a crisis atmosphere in the world but, at the same time, it has greatly improved China's relations with the United States as the two countries work closely together to put pressure on Pyongyang to give up its nuclear-arms program.

This new situation is recognized by both Washington and Beijing. U.S. Secretary of State Condoleezza Rice said on a swing through Japan, South Korea, China and Russia -- which along with the U.S. and North Korea make up the countries taking part in the "six-party talks" -- that some developments suggest that Beijing was becoming more of a partner on issues important to Washington.

Christopher Hill, the assistant secretary of state for East Asia responsible for the North Korea talks, said at a forum in Washington that the two countries have "really come closer together as a result of this terrible provocation by the North Koreans."
