The timing seems ominous. As rival American and Chinese warships assert themselves in the disputed South China Sea, the United States Geological Survey reported 20 minerals on which the U.S. imports all of its supply. Included are rare earths—coming almost entirely from China, of course. It was a 2010 conflict in the same troubled waters between Japan and China that caused the latter country to cut off rare earths exports to its adversary. As other supply chains broke apart, REE prices went on an exponential tear. Might China do that again and, this time, are American decision-makers sufficiently concerned?
