The dollar closed at 7.7740 yuan, down from 7.7900 on Tuesday. On the same day, Vice Premier Wu Yi said China will strive to reduce the trade imbalance in 2007. The trade surplus hit US$177 billion in 2006. The newspaper said the market saw the official comments as a signal that the yuan may be given more room to rise this year.
