Who can be sovereign?

Put the pieces together and the picture is clear. China built its position over decades, and today it holds almost every stage of the chain by itself: the refineries, the magnet factories, the technology, and the power to decide who gets them. It needs no alliance to do this. When it lacks raw material, it buys it abroad and keeps the processing at home. Part of the reason it stands alone is simple: for decades it accepted the pollution that others refused.

The West is in the opposite position. No Western country can rebuild the chain alone: it needs mines in one country, refining in another, magnets in a third, and suppliers willing to sell to it rather than to China. For the West, sovereignty over rare earths can only be shared with partners.

That is why countries with untapped reserves have become prizes, and why Brazil matters now. It holds some of the world's largest reserves. Its first large mine, Serra Verde in Goiás, started production in 2024 and at first had to sign ten-year deals to sell its concentrate to Chinese processors, because no one else could refine it. In late 2025 it cut those contracts short, and in April 2026 USA Rare Earth agreed to buy it for $2.8 billion, with all its Phase 1 output going to a US government-backed buyer for 15 years, and the deal closed on 3 September 2026; the EU is pitching Brazil a deal of its own. In September Brazil passed a critical-minerals law; signing it, Lula said the country's sovereignty was not for sale, and on 25 October he was re-elected. The West needs partners like Brazil to escape China; Brazil wants to stay sovereign itself.

And rare earths are a dirty business. Mining and separation leave radioactive residue, toxic wastewater and damaged land; in China they caused landslides and polluted rivers, and workers in mining regions have suffered high cancer rates. For thirty years the West let China carry these costs; Mountain Pass, then the only US mine, closed in 2002 after a toxic spill. Real sovereignty would mean taking them back: mines, separation plants and their waste. Framed as a security emergency, that can mean fast-tracked permits and weaker environmental rules. Sovereignty has a price, and it is not only paid in money.

Every side now claims sovereignty. China comes closest to having it; the West is trying to build it with others. Whether that can work is what the data on this site let you check. The next test is the deadline: the pause on China's October 2025 controls was set to end on 10 November 2026, and the wider truce now runs to 10 January 2027.
