China and the Future of Rare Earth Elements

A recent diplomatic spat between China and Japan has heightened territorial tensions and called attention to China’s growing forcefulness with foreign powers. One of the more intriguing aspects of this development was China’s suspension of the export of “rare earth” elements (REE) to Japan. REE comprise 17 metallic elements with a variety of modern industrial and commercial applications ranging from petroleum refining to laptop computers to green energy applications to radar. China produces roughly 95 percent of the global supply of REE and Japan is the largest importer. China’s disruption of REE shipments to Japan has caused alarm among other importer countries, bringing new urgency to the search for new supplies and substitutes.
