Deng Xiaoping's observation that rare earths were to the Chinese economy what oil is to Saudi Arabia's has proved accurate. Like Saudi Arabia and its oil reserves, China has gradually retained more and more of its rare earth elements for domestic use over the past decade. Supplying roughly 95 percent of the world's rare earth consumption, China shocked markets with its sudden restrictions on exports in 2010 and 2011, cutting quantities sent to Japan and then the U.S. and other Western trading partners in the aftermath of a maritime incident off the disputed Senkaku Islands. Rare earths take longer to find and extract than oil, and many of the world's mines had closed over the years when China was becoming the world’s principal supplier.
