This year, more than 200 American exhibitors, including 17 first-timers led by the U.S. government, participated in the CIIE, which is the largest U.S. delegation in the history of the Expo. In the past six years, American exhibitors ranked among those at the forefront of participating countries in the Expo in terms of exhibition area and the number of enterprises. U.S. Ambassador to China R. Nicholas Burns said U.S.-China economic and trade cooperation is very important and that the U.S. does not seek to "decouple" from China. As the world's first import-themed national exhibition, the cumulative intended turnover of the first five CIIE was nearly $350 billion, and about 2,000 first exhibition goods were unveiled.
