** FILE ** The late Chairman Mao Tse-tung’s face is seen on a pack of bills of Chinese yuan next to the U.S. currency after the Chinese government strengthened the state-set exchange rate of the yuan to 8.11 to the dollar from 8.277 where it had been fixed for more than a decade, in Shanghai in this July 21, 2005 file photo. China’s government said Thursday, May 11, 2006 it would stick to its currency reform plans despite U.S. complaints that it is moving too slowly in letting the yuan rise against the dollar.
