The Bush administration accused China on Friday of pirating American books, films and tapes and raising new barriers to sales of U.S. goods.

"Book and tape piracy is widespread," said the annual trade barrier report of U.S. Trade Representative Carla M. Hills.China's exports to the United States exceeded the value of its U.S. imports by $10.4 billion in 1990, up $4.2 billion.

The report was less critical of Japan, though Joshua Bolten, Hills' general counsel, said Japan still puts up many serious barriers to U.S. trade.

Japan had a much bigger surplus than China in trade with the United States, $41.1 billion last year, but that was $7.9 billion less than the year before.
