Rare earths are important to a number of high technology industries, including renewable energy and various defense systems. China’s position as the world’s dominant producer and supplier of rare earths (97% of total output) and its policies to limit exports have raised concerns among many in Congress, especially given the importance of rare earths to a variety of U.S. commercial industries (e.g., hybrid and conventional autos, oil and gas, energy-efficient lighting, advanced electronics, chemicals, and medical equipment), as well as to U.S. defense industries that produce various weapon systems.
