China bans export of rare earths processing tech over security

China, the world’s top processor of rare earths, banned the export of technology to make rare earth magnets on Thursday, adding it to a ban already in place on technology to extract and separate the critical materials.

Rare earths are a group of 17 metals used to make magnets that turn power into motion for use in electric vehicles, wind turbines and electronics.

“This should be a clarion call that dependence on China in any part of the value chain is not sustainable,” said Nathan Picarsic, co-founder of the geopolitical consulting firm Horizon Advisory.
