On June 22, 2007, Chinese Vice Foreign Minister Dai Bingguo, who was in the United States for the fourth Sino-U.S. strategic dialogue, met in Washington respectively with U.S. Secretary of State Condoleezza Rice and National Security Advisor Stephen Hadley. Both sides exchanged views on the bilateral relationship, the Taiwan question, as well as the Korean Peninsula nuclear issue, the Iranian nuclear issue, Sudan's Darfur and other international and regional issues of common concern.

Dai said the Sino-U.S. relationship has witnessed great progress in recent years and both sides should make joint efforts to further broaden common interests, enhance strategic mutual trust and promote bilateral cooperation. Dai stressed that both sides should also handle the Taiwan issue properly to ensure a sound and steady development of the bilateral relationship and contribute to global peace and development.

Expressing satisfaction with the strategic dialogue, the U.S. side said U.S.-Chinese relations are based on a solid foundation and the world will benefit from a strong China, as well as greater cooperation between the two countries in dealing with common problems. The U.S. side also reaffirmed its one-China policy and ruled out any change in that policy.

From June 20 to 21, 2007, China and the United States held their fourth round of strategic dialogue in Washington and the state of Maryland. Chinese Vice Foreign Minister Dai Bingguo and U.S. Deputy Secretary of State John Negroponte co-chaired the dialogue meeting, at which both sides had a frank and in-depth exchange of views on issues concerning Sino-U.S. relations that are of strategic, long-term and overall significance, as well as major international and regional issues of mutual concern.
