WASHINGTON, Dec 23 (Reuters) - China has refused repeated U.S. requests to eliminate export restraints on rare earths that have created concern among its trading partners, the U.S. Trade Representative's office said on Thursday.
"Going forward, the United States will continue to pursue vigorous engagement with China on this issue and will not hesitate to take further action, including WTO dispute settlement, if appropriate," USTR said.
