Geneva, April 10:

The United States filed two new complaints against China at the World Trade Organization on Tuesday over copyright policy and restrictions on the sale of American movies, music and books, trade officials said.

The move at the WTO comes a day after US Trade Representative Susan Schwab said American companies were losing billions of dollars annually from piracy levels in China that “remain unacceptably high.” The Chinese Commerce Ministry on Tuesday expressed “strong dissatisfaction” at the US action.

“The two cases have been submitted,” said Magda Siekert, a spokeswoman for US mission to international organizations in Geneva. The formal requests for consultations were not immediately made available.

One case contends that Beijing’s lax enforcement of copyright and trademark protections violates WTO rules, Schwab told reporters in Washington on Monday. The other argues that Beijing has erected WTO-illegal barriers to the sale of US-produced movies, music and books in China.

“Excessively high legal thresholds for launching criminal prosecutions offer a safe harbor for pirates and counterfeiters,” the office of the USTR said on its Web site. “Pirates and counterfeiters who structure their operations to fit below those thresholds face no possibility of criminal sanction.”

China is one of the world’s biggest sources of illegally copied goods ranging from movies, music and designer clothes to sporting goods and medications. But the WTO’s scope would focus on whether Beijing has taken sufficient action to stamp out intellectual property theft.

“The Chinese government has always been firm in protecting intellectual property rights and attained significant achievements in this respect,” Commerce Ministry spokesman Wang Xinpei said in a statement.

Wang criticized the US action and said it “will seriously undermine” economic and trade relations between the two countries.

The second case — focusing on China’s obligations under the General Agreement on Trade in Services and the terms which it entered the global commerce body in 2001 — alleges that Beijing has failed to remove import and distribution restrictions on copyrighted US goods including newspapers, magazines, CDs, DVDs and video games.

For some products, distribution is limited to Chinese state-owned companies, the US contends. For others, foreign companies face restrictive requirements that do not extend to Chinese competitors.

The new cases are the latest move against China on the part of the Bush administration, which is trying to deal with rising political anger over America’s soaring trade deficit, which set a record for the fifth consecutive year in 2006 at $765.3 billion.
