North Korean soldiers stand on duty along the waterfront of the North Korean city of Sinuiju, opposite the Chinese border city of Dandong in northeast China, Thursday, Oct. 19, 2006. U.S. Secretary of State Condoleezza Rice arrived in South Korea on Thursday to push Seoul to fully support sanctions against North Korea, while Chinese envoys were apparently in Pyongyang warning the reclusive country against more nuclear tests. China could play the most important role in restraining the North because the Chinese have long been the impoverished nation's closest ally and its biggest source of trade and fuel.
