A U.S.-China rare earth truce is technically in effect, but China is still throttling shipments, shortages persist, and Trump left Beijing last week without a confirmed extension of the agreement, which expires in November 2026. For investors watching the domestic rare earth sector, the fine print matters more than the headline. China controls roughly 70% of global rare earth mining and processes between 85% and 90% of the global supply. Those minerals, which are used in permanent magnets for AI data centers, electric vehicles, and military hardware, don't have a quick Western replacement. The truce bought time, but the underlying problem is unchanged. That's the setup Sean Brodrick of Weiss Ratings has been watching closely. His thesis: even if China eases supply, the U.S. government has committed to maintaining a price floor for critical domestic producers, meaning the economics don't collapse just because Chinese exports resume.Get USA Rare Earth alerts:Sign Up Washington has made its strategic priorities clear, and it's backing them with capital. And, as Brodrick notes, China has shown a willingness to reimpose restrictions when it suits them. The truce clock is already running. The Minerals Powering the New EconomyRare earth elements aren't a niche industrial input; they're embedded in the infrastructure of the modern economy. The four key magnetic rare earths—neodymium, praseodymium, dysprosium, and terbium—are essential for the permanent magnets that run everything from EV motors to AI data center equipment. The heavy rare earths, such as dysprosium and terbium, are particularly critical because they protect magnets from heat-induced degradation, making them indispensable in high-performance applications. China's export control playbook has specifically targeted these materials. Restrictions introduced in late 2024 and expanded through 2025 covered gallium, germanium, antimony, and several rare earth elements. The November 2025 truce paused those controls, bu...
