BEIJING (AP) — China has said it opposes the release of a WTO report on its curbs on rare earths exports following news accounts that it rejects Beijing's policy as a trade violation.

The Commerce Ministry said Friday the report by a panel of WTO experts is not a final ruling and leaks would violate the trade body's rules.

Japan's Jiji Press news agency and The Financial Times, citing unidentified sources, have said the report sides with the United States, the European Union and Japan in a dispute over Chinese curbs on exports of rare earths.

Beijing has tightened control over rare earths mining and exports in hopes of capturing more of the profits that flow to Western makers of lightweight batteries and other products made of rare earths.
