On 09 October, China expanded rare earth export restrictions, limiting shipments of materials and processing technologies to foreign defense and advanced semiconductor industries. China accounts for over 90% of processed rare earths and magnets. Exports of 12 of the 17 rare earths are now restricted after adding holmium, erbium, thulium, europium, and ytterbium, along with related materials. The elements are used in electric vehicles, aircraft engines, and military radars. The rules mirror US controls on semiconductor exports to China and come ahead of possible talks between Presidents Trump and Xi Jinping later this month.
