SCOTT JAGOW: The U.S. is not alone in its dispute with China over piracy — the European Union and Mexico have asked to participate in World Trade Organization talks over Chinese copyright and trademark policy.

But the presence of these two economic heavyweights in its corner won’t necessarily help the Americans. Marketplace’s Jeff Tyler explains.

JEFF TYLER: In two piracy cases before the World Trade Organization, the U.S. alleges China doesn’t do enough to punish those who illegally copy films and music, while it also blocks access to Chinese markets.

Professor Lon Sobel at Southwestern Law School says having the European Union and Mexico on our side won’t likely sway the Chinese.

LON SOBEL: The policymakers in China will feel all of the pressure that they are able to feel simply as a result of the U.S. claim.

JEFF TYLER: With Americans buying billions of dollars worth of Chinese-made products, he says the threat of U.S. tariffs alone should worry China. Why are Mexico and the E.U. getting involved?

LON SOBEL: They could impose tariffs as well on Chinese made goods.

JEFF TYLER: Chinese leaders are reportedly upset that the issue was sent to the WTO, saying the move could damage trade relations. I’m Jeff Tyler for Marketplace.
