China still controls rare‑earth choke points
Chinese rare‑earth exports rose to about 62.6 thousand metric tons in 2025 even as Beijing tightens export controls, underlining that volume alone doesn’t remove strategic leverage. The IEA warns that diversifying downstream processing would need roughly $60 billion of investment, because separation, metallization and magnet production—not just mining—are the true bottlenecks for industries like EVs and defense. That means manufacturers who think they’ve solved ‘supply’ by switching ore sources may still be vulnerable at the refining and component level. ((statista.com), (gtreview.com), (businessgreen.com))
China shipped more rare earths in 2025 than in any year since 2009, with exports rising to about 62,600 metric tons. Beijing still tightened controls in April 2025 on some medium and heavy rare earth items, so the squeeze is no longer about whether material exists at all, but about who can legally get which forms of it. (statista.com, english.mofcom.gov.cn) Rare earths are a group of metals used in very small amounts inside very important parts. A wind turbine motor, an electric vehicle drive unit, or a missile guidance system can depend on magnets made from neodymium, praseodymium, dysprosium, or terbium, even though the finished product weighs far more than the rare earths inside it. (iea.org) The easy mistake is to think the mine is the whole story. The harder step is turning mixed ore into separated oxides, then into metal, then into finished magnets, which is closer to baking, smelting, and precision machining in sequence than to digging rocks out of the ground. (iea.org) That middle stretch is where China still dominates. The International Energy Agency said in April 2026 that China accounts for around 60% of global mined production of magnet rare earths and more than 90% of refining. (iea.org) So a carmaker can sign a supply deal with a mine in Australia or the United States and still hit the same wall later. If the ore, oxide, alloy, or magnet still has to pass through Chinese separation plants or magnet factories, the dependency just moved downstream instead of disappearing. (iea.org, iea.org) The International Energy Agency put a price tag on fixing that gap: about $60 billion. That investment is needed not mainly for new holes in the ground, but for processing, metallization, magnet making, recycling, and the transport and power links that let those plants run at industrial scale. (iea.org, businessgreen.com) That is why export tonnage can rise at the same time strategic leverage rises. Selling more raw or semi-processed material does not stop Beijing from controlling the higher-value steps where a separated oxide becomes a military-grade alloy or a high-performance permanent magnet. (statista.com, iea.org) The April 4, 2025 controls showed how targeted that leverage can be. China’s Ministry of Commerce and General Administration of Customs said samarium, gadolinium, terbium, dysprosium, lutetium, scandium, and yttrium related items would require export control treatment, focusing attention on the heavier rare earths that are especially hard to replace in heat-resistant magnets and defense systems. (english.mofcom.gov.cn) For manufacturers, the supply chain problem now looks less like “find another mine” and more like “rebuild an entire industrial neighborhood.” A magnet plant needs separated chemicals, metalmaking know-how, specialized equipment, skilled workers, environmental permits, and customers willing to sign long contracts before the first batch ships. (iea.org, gtreview.com) That is why the headline number on exports is misleading on its own. The world can buy more rare earth material from China in 2025 and still be more exposed than it was before, because the real choke points sit in separation lines, furnaces, and magnet workshops that take years and billions of dollars to duplicate.
