Not every country has economically extractable heavy rare earths, resource =/= reserve. X discovers rare earth is the same as X discovers plants, and then assume every country can build a robust biofuel economy. Reminder PRC has the MOST shale deposits in the world, they're just buried very deep and economically AND technically not productive to extract at scale.
PRC's main choke hold is HeavyREE, more specifically processing of ionic clays that is GEOGRAPHICALLY SCARCE like economically extractable oil deposits, which enables economic leeching of heavy strategic rare earth AT SCALE. Think hunting whales for blubber vs drilling oil, supports entirely different tiers of proliferation and use. At scale is key, west never used HREEs at scale until PRC commoditized them by exploiting specific geology mostly limited to south PRC, Myanmar, parts of Brazil but deposits now also found in Australia because Australia has everything. So the real question is can long will it take AU+co to discover and build the entire HREE infra based on deposit types only PRC has real experience with.
