U.S. complaints against China at the World Trade Organization over alleged "copyright piracy" issues will not help solve problems, a spokesman for China's National Copyright Administration (NCA) said Tuesday.

"I don't deny that IPR infringement and piracy occurs in the Chinese market, but that doesn't mean the United States is founded to file complaints against China in the WTO," said NCA spokesman Wang Ziqiang at a press conference.

He said China has made tremendous efforts in IPR protection over the past 20 years. But "copyright infringement and piracy is a global and universal problem, which can not be eradicated overnight," said Wang.

The spokesman said China and the United States have regular consultation mechanisms to address IPR issues and IPR problems could be solved effectively through communication.

"Filing complaints in the WTO is not conducive to improving China-U.S. cooperation in IPR protection," he said at a press conference.

The United States last Tuesday formally filed two WTO complaints against China over so-called copyright piracy and restrictions on the sale of U.S. books, music, videos and movies.

The two new cases were seen as the latest effort by the Bush administration to increase pressure on China in the area of trade despite Beijing's efforts to crack down on piracy.
