She will co-chair the 17th meeting of the Sino-U.S. Joint Commission on Commerce and Trade (JCCT) in Washington with U.S. Secretary of Commerce Carlos Gutierrez and Trade Representative Rob Portman.

Li Changjiang, Minister of the General Administration of Quality Supervision, Inspection and Quarantine, is a member of the delegation.

At a meeting in Beijing last week, Wu and Gutierrez vowed to improve bilateral trade and economic ties to create a "positive atmosphere" for the meeting between Chinese President Hu Jintao and U.S. President George W. Bush in Washington next month.

Sino-U.S. trade hit 212 billion U.S. dollars last year. China has become the fourth largest export market and the third largest trade partner of the United States.
