Pini Althaus saw the signs. In 2023, he left the company he founded, USA Rare Earth, to develop critical minerals mining and processing projects in central Asia, after realizing that the U.S. will need all the international help it can get to end China’s supply chain dominance.

“I realized we only have a handful of large critical minerals projects that were going into production between now and 2030,” Althaus, chairman and CEO of Cove Capital, told Fortune. “I understood that we’re going to have to supplement the United States critical minerals supply chain with materials coming in from our allied and friendly countries.”

Over a series of decades, China built up its stranglehold on much of the world’s critical minerals supply chains, including the 17 rare earths, used to make virtually all kinds of high-performance magnets and parts for vehicles, computers, power generation, military defense, and more. The rest of the world deferred to Beijing in exchange for cheap prices.

Amid an ongoing tariff war with the U.S.—and a temporary truce—the Trump administration is racing to build up domestic mining and processing capabilities, while also developing the global partnerships necessary to eventually undermine China, which controls 90% of the world’s rare earths refining.
