WASHINGTON (Reuters) - The U.S. Trade
Representative's office is "very concerned" about China's
export restraints on rare earth materials and has raised its
concerns with China, a spokeswoman said Tuesday.
The USTR was responding to China's move to cut its first
round of rare earth export quotas for 2011 by more than 10
percent from year-earlier levels.
