China Cutting Back 72% Of Its Exports Of Rare Earth Metals
Posted By thestatedtruth.com on August 29, 2010
Interesting to say the least….rare earth elemnts are used in almost everything that is high tech…….
Bloomberg reports that China is cutting back 72% of its exports of Rare Earth metals. Â China has said that environmental issues are the reason for the cutbacks.
72% drop in availability of any commodity is important. RE’s are important. Japan and the U.S. are already protesting the ban. The rest of the world’s manufacturing base will soon follow. This could become an interesting problem.
And all those folks were saying that China would be the world’s economic growth engine.
