China Holds A Dangerous Card Over America

China’s chokehold on critical minerals now reaches deep into America’s weapons, energy, and tech supply chains, leaving our nation dangerously exposed when Beijing decides to weaponize trade.

Story Snapshot

China controls most global rare earth mining, refining, and magnet making, giving it leverage over U.S. defense and industry.^[5]^[10]
Beijing has already used export restrictions and tariffs to squeeze rare earth supplies after U.S. trade actions.^[5]^[6]
American mine projects take decades, making it hard to escape dependence quickly despite Trump-era pushback.^[1]^[6]
New U.S. and allied efforts are rising, but heavy rare earths and high‑end magnets still sit under Chinese control.^[1]^[8]

How China Built a Grip on America’s Critical Materials

Chinese leaders spent more than thirty years locking up mines, refining plants, and magnet factories around the world, turning critical minerals into a pressure point on the United States.^[1] Today China produces well over half of the world’s rare earth raw materials and controls nearly ninety percent of the refining that turns them into usable metals.^[5]^[6] That refining step is the real choke point, because rare earth ores mined elsewhere, including in America, still often need Chinese facilities to become finished products.^[8]

Rare earth elements sit inside missile guidance systems, jet engines, tank electronics, and advanced radar, so control of these materials means leverage over our military.^[1]^[5] Analysts describe China’s position in heavy rare earths and permanent magnets as one of the most serious choke points in the entire critical mineral system.^[1] These magnets power everything from electric vehicle motors to precision weapons, which means Beijing’s decisions on exports can slow or stop production lines far beyond its borders.^[6]^[10]

Export Weaponization: From Tariffs to Technology Bans

Chinese officials have already shown they are willing to use this leverage when political fights flare up.^[5] After U.S. tariffs and new blacklists on Chinese defense-linked firms, Beijing answered with trade restrictions on dozens of American companies, including rare earth producers.^[5] Economists warn that newly announced extraterritorial export rules could block products worldwide if even a tiny share of their value comes from Chinese rare earths or Chinese-controlled processing technology.^[6] That kind of rule would let Beijing reach deep into foreign factories and supply chains with the stroke of a pen.^[6]

Recent export controls cover not only raw minerals but also magnet production know-how, which makes it harder for other countries to copy China’s success.^[1] Heavy rare earths such as dysprosium and terbium, crucial for high-performance magnets that work in extreme heat and stress, face special controls.^[1] These metals are key in jet engines, advanced motors, and some precision-guided systems. When China tightens shipments, prices spike and smaller producers struggle to compete, reinforcing the very dominance that caused the worry in the first place.^[6]

America’s Slow Supply Chain and Trump-Era Pushback

The United States still relies on one major rare earth mine at Mountain Pass, California, and has limited domestic refining capacity, which leaves our industry exposed.^[8] Studies show China supplies more than fifty percent of U.S. demand for many nonfuel minerals and remains the dominant source for rare earth imports.^[8]^[10] Building new mines and processing plants inside our borders can take many years because of permits, lawsuits, and environmental reviews, which slows any plan to break dependence quickly.^[7] This long timeline clashes with the near-term risk from sudden export crackdowns.

The Trump administration and later policies have begun to push back with tariffs, government support, and industrial strategies aimed at rebuilding critical mineral chains on friendly soil.^[1]^[5] Washington has put money and political muscle behind rare earth mining, refining, and magnet manufacturing, and signed deals with partners like Australia, India, and Japan to diversify imports.^[8] Yet experts warn that even strong efforts may not fully overcome China’s grip on heavy rare earths and magnets, because Beijing still controls upstream resources and key processing technology.^[1]^[6]

Allied Moves and the Fight for Long-Term Security

Allies in the Group of Seven and the wider Quad partnership have begun to set targets to keep any single supplier, including China, from controlling the bulk of their rare earth imports.^[8] These governments want more shared projects and joint financing so that new mines and refineries can spread across friendly nations, not just fall inside U.S. borders. Global reports show similar worries in Europe, where officials say high dependence on a few suppliers raises the risk of “resource nationalism” and export bans.^[9]^[11] The pattern is simple: concentration of supply invites political pressure.

The US Army just became a landlord for critical minerals — and almost nobody noticed.
For the first time, the Pentagon is allowing private companies to build mineral processing plants directly on US military bases. REalloys will construct a rare-earth separation facility at the…

Think tanks and security analysts now compare China’s mineral leverage to past energy shocks, arguing that rare earths could be used much like the Arab oil embargo of the 1970s.^[4]^[8] They recommend building domestic stockpiles, speeding permits, supporting alternative technologies that use fewer rare earths, and investing in recycling to cut fresh demand.^[7]^[10] For American conservatives, the lesson is clear: our nation should never allow an adversary to hold the keys to our weapons, our energy system, or our economy’s core industries, especially through supply chains built on hostile soil.^[5]
