China's rare earth export restrictions (2010)
China halted rare earth shipments to Japan after a territorial dispute in the East China Sea. Prices for some elements rose as much as tenfold within months, panicking electronics and defense buyers worldwide.
Japan and the U.S. scrambled for alternative suppliers and recycling; a World Trade Organization case later forced China to undo the quotas.
The episode turned rare earth supply into a strategic concern and launched repeated U.S. government efforts to rebuild domestic production.
This is the wake-up call that created the problem the Utah grant is meant to solve.
