Beijing has suspended exports of certain rare earth minerals and magnets that are crucial for the world’s car, semiconductor and aerospace industries.
Shipments of the magnets, essential for assembling everything from cars and drones to robots and missiles, have been halted at many Chinese ports while the Chinese government drafts a new regulatory system. Once in place, the new system could permanently prevent supplies from reaching certain companies, including American military contractors.
The official crackdown is part of China’s retaliation for President Trump’s sharp increase in tariffs that started on April 2.
