China warns it may squeeze rare‑earth exports during Trump–Xi Beijing talks

Rare earths are the quiet choke point in this whole U.S.-China fight. They are not actually rare in the ground, but the hard part is mining, separating, refining, and turning them into the magnets and materials that end up inside missiles, EV motors, wind turbines, chips equipment, and a lot of defense hardware. China dominates the processing side, and that gives Beijing a lever Washington still struggles to replace. China reminded everyone of that again ahead of Donald Trump’s May 14-15 meetings with Xi Jinping in Beijing, where the official agenda is broader but the real pressure point is supply. (english.mofcom.gov.cn) So what changed? Not a brand-new embargo. The important move happened on April 4, 2025, when China put export controls on some medium and heavy rare-earth-related items. The list covered seven elements — samarium, gadolinium, terbium, dysprosium, lutetium, scandium, and yttrium — and took effect immediately. Beijing framed that as a dual-use export-control measure, not a blanket ban. But in practice, licensing power is leverage, because a country that approves, slows, or withholds licenses can squeeze supply without saying “ban” out loud. (english.mofcom.gov.cn) Why do these particular elements matter so much? Because the heavy rare earths are the ones that help magnets keep working under heat and stress — exactly the conditions you get in military systems and high-performance motors. Dysprosium and terbium are the names people keep coming back to for that reason. Samarium matters too, especially in samarium-cobalt magnets used where heat resistance matters more than raw cost. The catch is that the U.S. can mine more ore over time, but refining and magnet-making are the bottlenecks, and China is still the center of gravity there. That is why a licensing regime matters more than a headline tariff at this point. (english.mofcom.gov.cn) That is also why the Trump-Xi summit looks narrower than the rhetoric around it. The expectation going in is not some grand reset. Trump arrived in Beijing this week looking for practical wins — beans, beef, Boeing, maybe energy purchases, maybe an extension of the trade truce that has allowed rare earths to keep flowing. Reuters’ preview said the two sides were also discussing whether to lengthen that truce, but it was not clear before the meetings whether that would happen now. In other words, the biggest structural issue is on the table, but probably not close to solved. (usnews.com) Why does Beijing keep this card visible? Because it changes the bargaining math. Tariffs hurt, but they are noisy and reversible. Rare-earth controls hit deeper in the supply chain. They tell U.S. negotiators that even if Washington keeps raising duties, China still has a tool that can jam production in sectors the U.S. treats as strategic. That includes defense and advanced manufacturing, which makes the threat more credible than a lot of trade-war theater. Analysts heading into the summit were basically describing managed friction — enough commerce to calm markets, not enough trust to unwind the real rivalry. (usnews.com) There is one important nuance here. China has spent months saying these are export controls, not export bans, and that compliant civilian applications can still be approved. It even said in June 2025 that it was accelerating reviews and had approved some applications. But that does not make the leverage disappear. A valve you control is still a valve, even if you insist it is open most of the time. (english.gov.cn) The bottom line is simple. Trump can still come home from Beijing with purchase deals and a calmer headline. But China’s rare-earth position means the deeper balance of power in this negotiation has not really moved. Until the U.S. builds more refining and magnet capacity outside China, Beijing’s warning does not need to be dramatic to be effective. (usnews.com)
