The United States needs to ease its control of hi-tech products to China to advance trade and investment, said Zhang Yesui, Chinese Ambassador to the United States, in New York on November 18.

Speaking at the first China General Chamber of Commerce-U.S.A. Annual Gala, Zhang told business leaders from both countries that U.S. exports to China, which accounted for less than 7 percent of China's total imports, was not compatible with the status of the overall bilateral relationship and China's demand.

"This will provide further opportunities to farmers, manufacturers and workers in the United States and other parts of the world," Zhang said.

U.S. exports to China were growing slowly, and the proportion of U.S. hi-tech products in China's overall hi-tech imports had been declining considerably, from 18.3 percent in 2001 to only 7.1 percent in 2010.
