China Moves to Strengthen Grip Over Supply of Rare-Earth Metals

China is building strategic reserves in rare-earth metals, an effort that could give Beijing increased power to influence global prices and supplies in a sector it already dominates.

Details of the stockpiling plans haven't been made public. But the outlines of the effort have emerged in recent statements from Chinese government agencies, state-controlled companies and reports in government-run media. The reports say storage facilities built in recent months in the Chinese province of Inner Mongolia can hold more than the 39,813 metric tons China exported last year.

China controls more than 90% of current global supply of rare-earth metals—a group usually classified as 17 elements and sometimes are called "21st Century gold" for their importance in such high-tech applications as laser-guided weapons and hybrid-car batteries. Beijing has been tightening its exports with a quota policy.

Mining companies around the world have responded by taking steps to increase production. Many rare-earth minerals aren't actually rare, and China doesn't have a monopoly on deposits of any particular rare-earth elements. The U.S. Geological Survey recently estimated that China has about half the world's 110 million metric tons of rare-earth deposits, however. Mining in the U.S. and elsewhere fell off several years ago, in part because of environmental concerns. Australia's Lynas Corp. U.S.-based Molycorp Inc. and other companies are ramping up operations. But a new mine can take a decade to develop, and processing of rare-earth elements will remain concentrated in China for years. (more)
