Why Should We Care if China Controls the World’s Rare Earths Supply? | with Melissa Sanderson

Melissa Sanderson returns to unpack why China’s grip on the world’s supply of rare earths has become one of the most consequential economic stories in the Indo-Pacific, and why a deadline just weeks away could reshape supply chains for everything from smartphones to fighter jets. Mel spent 21 years in the U.S. Foreign Service before moving into mining, and now serves as co-chair of the Critical Minerals Institute and a board member of American Rare Earths.

Mel opens with a promise: she’ll define rare earths, and then you can promptly forget the definition. What matters is what they do. A small handful of these elements make the magnets inside laptops, cell phones, electric vehicles, wind turbines, data centers, robotics, and missile guidance systems. America’s F-35 Joint Strike Fighter, which carries hundreds of pounds of rare earth content per aircraft, can’t fly without them.

Mel explains how Beijing built its dominance over four decades: large domestic deposits, a processing and manufacturing chain developed deliberately alongside them, and aggressive acquisition of mining concessions abroad through infrastructure-for-resources deals she calls neocolonial. Washington is now running the same playbook - creating friction with a European Union that accuses the U.S. of using its checkbook to crowd European buyers out of the market.

But the real chokepoint isn’t the rock in the ground. China mines roughly 60% of the rare earths used in magnets and controls 91% of refining and 94% of magnet manufacturing. Everything between the mine and the finished magnet is the issue.

When asked whether U.S. government equity stakes in mining companies count as industrial policy, Mel says that’s just market economics. Real industrial policy starts with the end user and works backward to the mine. What America is doing instead is “shotgunning resources”: building processing plants with no secured supply to run through them.

Beijing’s suspension of its expanded export controls expires November 10, and the measures snap back automatically unless China acts. Meanwhile, new rules bar Chinese-linked materials from the entire defense magnet supply chain starting January 1. Mel’s arithmetic is brutal: the deadline is months away; the fastest U.S. mine-and-processing build is three to four years.

Her bottom line? “No mine, no cell phone.” And for now, we need to play nice with China on rare earths.
