Rare earth cause debate in mining machinery area

Rare earth metals are used in the manufacture of almost every high-technology device -- from mobile phones and computers to batteries for electric cars. And demand is only growing. Rare earth metals are produced with mining machinery such as jaw crusher. Besides, many materials of machine equipment need rare earth.
But information from China’s government and the United States Geological Survey shows that China has reduced its export limits sharply in the past two years. Critics say this unfairly helps Chinese companies in the production of high-technology products. And, they say, it is a violation of World Trade Organization rules.
President Obama added that the United States has a productive economic relationship with China. But he said he would take action if American workers or businesses were facing unfair trade policies.
 However, China has his right to protect his own property. Obviously, China plays an important role in global economic. If it is a matter of rules, while who makes out the rules? As far as I know,  it just a matter of some developed countries' opinion, where start from their own benefits, not benefit for all of the world.
China says it follows WTO rules in exporting the minerals. In twenty ten, China mined about one hundred thirty thousand metric tons of rare earth metals. That was about ninety-seven percent of world production.
President Obama added that the United States has a productive economic relationship with China. But he said he would take action if American workers or businesses were facing unfair trade policies.
BARACK OBAMA: "This case involves something called rare earth materials, which are used by American manufacturers to make high-tech products like advanced batteries that power everything from hybrid cars to cell phones. We want our companies building those products right here in America. But to do that American manufacturers need to have access to rare earth materials, which China supplies. Now, if China would simply let the market work on its own, we'd have no objections. But their policies currently are preventing that from happening, and they go against the very rules that China agreed to follow.
China says it has restricted rare earth exports to meet needs at home. And it says its policy helps limit the environmental damage caused by over-mining. Therefore, the mining machinery manufacture in China is not so good as we think. But there are some oustanding enterprises still on the increasing by high tech and innovation. Some mining machine such as ball mill, cement mill has a good sales at home and broad.
