Washington, D.C. ? The Bush administration, facing increasing anger about soaring trade deficits, announced Friday it would impose sanctions against Chinese paper imports, opening a new avenue for beleaguered American manufacturers to seek government protection.

The action, announced by Commerce Secretary Carlos Gutierrez, reverses 23 years of U.S. trade policy by treating China, which is classified as a nonmarket economy, in the same way other U.S. trading partners are treated in disputes involving government subsidies.

The decision involved a case brought by NewPage Corp., a Dayton, Ohio-based paper company. It contended that its coated paper was facing unfair competition from imports from Chinese companies that receive improper subsidies from the Chinese government.

Commerce imposed penalty tariffs ranging from 10.9 percent to 20.4 percent on imports of glossy paper from China. The tariffs will take effect next week on a preliminary basis and will become final after a further Commerce review is completed in June.
