No faster way to wreck things than to turn a maniac loose in China shop.
Good write up on that link, one thing I have read, not in that one, is that most of China's rare earth production goes into products made in China, like magnets for motors, electronics, cell phones, and a reduction in sales of end products made in China will hurt China suppliers top to bottom.
I never thought stirring up trouble with a hornets nest was very smart.
