U.S. Vice President Dick Cheney (L) is greeted by his Chinese counterpart Zeng Qinghong at the Great Hall of the People in Beijing April 13, 2004. China has opposed U.S. weapons sales to Taiwan, which Cheney has supported, and said it was especially important not to send the wrong signal after the contested March 20 election won by a whisker by pro-independence President Chen Shui-bian.
