Editor's notes:

Rare earths elements, often referred to as "vitamins for industry", are widely used in industries, especially electronic devices. China owns about 30 percent of the world's total reserves of rare earths, but is satisfying about 90 percent of the world's total demand. This unfair situation was resulted from a long-term disorder in the international market. Recently, Chinese authorities plans to gradually reduce export quota of rare earths, with an annual cut of 2 to 3% and set up strategic reserves.
