    We should engage in meaningful negotiations," he told reporters after the consultations"Chinese ambassador to the United States Cui Tiankai said Friday "both China and the United States benefit from bilateral trade, so efforts to undermine Sino-US trade, or even slapping sanctions on China, I think would be off-target

    To ease tensions, China has been committed to a peaceful solution by supporting Security Council sanctions on one hand, and on the other proposing initiatives which aim to suspend hostilities by both Pyongyang and WashingtonThe ambassador said the US should refrain from issuing more threats

    Instead, Washington should do more to find effective ways to resume dialogue and negotiationscn]The United States should do more to resolve the nuclear crisis on the Korean Peninsula than it has, Chinese Ambassador to the US Cui Tiankai said on FridayCui made the remarks on the sidelines of a reception at the embassy in Washington to mark the 68th anniversary of the founding of the People's Republic of ChinaThe UN Security Council unanimously adopted resolution 2375 on Monday to respond to the Democratic People's Republic of Korea's sixth nuclear test, conducted on Sept 3
