china stockpiling rare earths

"Details of the stockpiling plans haven't been made public. But the outlines of the effort have emerged in recent statements from Chinese government agencies, state-controlled companies and reports in government-run media. The reports say storage facilities built in recent months in the Chinese province of Inner Mongolia can hold more than the 39,813 metric tons China exported last year.

...

At least 10 storage facilities are being built and managed by the world's largest producer of rare-earth metals, government-controlled Baotou Steel Rare-Earth (Group) Hi-Tech Co. Chinese state media reports say stockpiles may eventually top 100,000 metric tons."

Anyone still think China is going to ramp up rare earth exports again to lower prices and crush foreign production? With Chinas use of rare earths increasing and storage facilities of this size is it reasonable to think they may be planning to cease all exports in the next few years?
