If the New York Times' ace China correspondent Keith Bradsher is to be believed, China has has halted exports of rare earth elements to Japan, in protest of its neighbor's detention of a Chinese fishing boat captain.
A spokesman for China's Ministry of Foreign Trade and Economics is denying that any such trade embargo exists, but Bradsher's article makes a convincing case that some kind of message has come down from on high to restrict the flow of minerals. Regular readers of HTWW will understand the significance of the move. Rare earth elements play an extraordinarily important role in the high tech, clean energy economy -- as well as advanced military technology such as missile guidance systems.
The Prius, for example, depends heavily on the rare earth elements neodymium and lanthanum. Last year Reuters reported that each Prius motor "requires 1 kilogram (2.2 lb) of neodymium, and each battery uses 10 to 15 kg (22-33 lb) of lanthanum." China controls 90 percent of the production and processing of neodymium.
