(Reuters) - The United States wants more countries to boost production of so-called rare earth metals used in clean energy technology products to break China's monopoly on the supplies, a top Energy Department official told Congress on Thursday.
Diversifying supplies of the rare metals is important to the Obama administration, because they are used in electric cars, solar panels and wind turbines, all of which the White House is promoting in its overhaul of U.S. energy policy.
China accounts for 95 percent of global production of rare earth metals. Its market dominance came in focus this month when industry sources cited concerns Beijing was apparently holding back shipments to Japan. A Japanese trading firm source has said China ended the de facto ban, but Japanese customers are looking elsewhere for supplies.
The incident fueled concern that clean-energy products could become more expensive and harder to manufacture outside of China.
