China's Rare-Earth Advantage: A Strategic Weapon Against the U.S.
In the heightening economic battle between China and the United States, Beijing has deployed one of its wild cards: rare earth elements.
On April 4th, in response to U.S. tariffs, China restricted exports of seven rare earth elements to the United States. These metals, dysprosium and terbium, are two examples, are the backbone of everything from wind turbines, electric cars, to really any sophisticated mechanical systems. It is not a complete ban, but the fact that China is prepared to use its dominance as leverage in a market where it already has a grip not only on mining, but 98% of the world's processing, is a stark warning. With limited viable alternatives and few global supply chains, the U.S. is left vulnerable.
The implications could be huge. Prices are already climbing, and though there are some inventories remaining, they'll be used up in a matter of months. The civilian end of things like green energy and electric cars would get squeezed first, followed by defense. As the U.S. scrambles to fund mines in California, Brazil, and South Africa, and develop a rare-earth processing facility in Texas, it could take years to build a supply chain to rival China's. History suggests China will use this leverage selectively, but if push comes to shove, then who knows what could come next…
