The United States, the European Union and Japan have filed a trade case over China's export restrictions, which limit the amounts of rare earth minerals China will export to other countries for the production of many high-tech devices.
China produces 97% of all rare earths, according to the EU. The materials are used in products such as flat-screen televisions, smart phones, hybrid car batteries, wind turbines, energy-efficient lighting, electronics, cars and petroleum.
For information on the production of these minerals in China, see the following U.S. Geological Survey Report
