Rare lands are a strategic advantage for China. A large part of the reserves of these minerals are found in the Asian country. However, rare earth mining is highly polluting, so China has undertaken to limit its production.
It has imposed quotas on the volume of rare earth exports since 2010 so that it can take advantage of the world's dependence on this mineral. There are quotas on production, in addition to export quotas, which respond to both the inherent pollution of these materials and the incipient diversification of production.
Rare earth mining is a double-edged weapon for the environment, on the one hand, it means an important input; and on the other hand, the pollution it represents has been devastating for some regions in Asia.
