A government report released Friday calls on China to slash tariffs and root out piracy of Japanese products.

The report of unfair practices by trading partners also renewed criticism of U.S. steel import restriction policies, following the U.S. levying of tariffs to safeguard U.S. steelmakers and Japan taking issue in January with a U.S. antidumping measure on surface-treated steel sheets.

The 2002 Report on the World Trade Organization Consistency of Trade Policies by Major Trading Partners takes up policies Japan considers inconsistent with the WTO. It covers 11 countries and regions, including, for the first time, China and Taiwan.
