Trump wants to secure the minerals the U.S. needs for everything from smartphones to jet fighters by striking deals in Ukraine, Greenland and even Russia. But even if the Trump administration secures more mines for American companies through agreements like the mineral-rights deal being discussed with Ukraine, it may have to send much of the minerals to China—its main geopolitical rival—to be processed…

In truth, the U.S. already has abundant supplies of rare earths, but it relies on China to refine them. That is because the U.S. has lost much of its capacity to process minerals, while China has become the world’s dominant refiner of rare earths, cobalt, copper and many other metals.

Until the 1990s, the U.S. was a major refiner of minerals and metals. But then China emerged as the dominant player, powered by its cheap labor force and looser environmental regulations of a sector that can be highly polluting. The voracious need of Chinese manufacturers for raw materials during the country’s years of explosive growth was also a boon for Chinese refiners. Today, the sheer scale of China’s refining industry makes it difficult for others to compete. According to industry estimates, the cost of building a refinery plant in China is a third of the cost in the U.S.
