China rare earth export restrictions (2010)
China, then supplying over 90% of the world's rare earths, cut export quotas to Japan after a territorial dispute. Prices for some elements rose tenfold within months, exposing how vulnerable importers were.
The US, EU and Japan scrambled for alternative suppliers and filed a WTO complaint; China later eased the quotas.
The episode triggered a global wave of critical-minerals diversification programs, including the EU's raw-materials strategy.
The 2010 scare is why the EU now treats lithium as a strategic raw material — import dependence drives the CRMA's targets and fast-track designations.
