There is a pair of numbers worth memorizing: China controls roughly 70% of rare-earth mining and roughly 90% of processing, on the standard estimate compiled by the Center for Strategic and International Studies. The United Kingdom's £50 million package of 22 June 2026 — for domestic extraction, processing and recycling of critical minerals — is best read against them. The UK announcement itself names no country and no percentage; it speaks of supply chains "increasingly concentrated and vulnerable to disruption." The euphemism and the numbers describe the same fact.
Read those two figures against each other and the whole shape of critical-minerals statecraft falls out. The gap between 70 and 90 is the chokepoint. It tells you that even where the rest of the world digs the ore — and the world does dig a meaningful share — the metal still has to travel to China to become usable. Mining is contestable. Processing is the bottleneck.
Here is why the distinction is real and not rhetorical. A rare-earth deposit is a rock containing a mix of elements in small concentrations. To turn that rock into the neodymium-praseodymium oxide that goes into a magnet, you must crush it, leach it, and then separate the individual rare earths from one another — a chemically punishing, capital-intensive, environmentally heavy step. Separation is where the know-how, the permits, the effluent handling, and the sunk capital concentrate. A country can open a mine in a few years. Building separation and magnet-making capacity at scale, cleanly, and at competitive cost is the harder, slower thing — which is precisely why China's share of it sits near 90%.
That is the leverage. Control the processing step and you control whose ore becomes a product, regardless of who owns the mine. It is the reason an export control on processed rare earths bites harder than one on ore: the world can find other holes in the ground, but it cannot quickly find other refineries.
Now watch where the sovereign money is actually being pointed, because the instruments confirm the diagnosis. The Asian Development Bank's (ADB) Critical Minerals Financing Facility, announced 3 May 2026, spans the chain from mining through processing — and regional coverage framed it squarely as a counter to Chinese processing dominance. The US$500 million Critical Minerals Supply Chain Finance Alliance built by the Korea Export-Import Bank (KEXIM) and the ADB at the same annual meeting (a sized envelope, not a deployed sum) is layered on top, with South Korea positioning as the Indo-Pacific financial anchor. And the UK's own £50 million splits into a £25 million accelerator spanning extraction, processing and recycling, a £20 million magnet hub, and up to £5 million for demand aggregation — recycling being, in effect, a second path to refined metal that bypasses the mine entirely.
The pattern across these is consistent: the capital is aimed downstream. A facility to dilute processing dominance. An alliance anchoring supply-chain finance, not extraction subsidies. A national package that funds refining and recycling, not just digging. When sovereign actors put their balance sheets behind the midstream rather than the mine, they are reading the same 70-versus-90 gap and acting on it.
A caveat the discipline requires: the facility and the alliance are framework objects — a standing mechanism and an envelope — not disbursed money. They name an intention to finance processing; they have not yet, on this evidence, built a refinery. The gap between announcing a facility and pouring concrete is exactly the gap between 70 and 90 in reverse — easy to declare, hard to close.
The mine is where the story looks like it should be. The refinery is where the power actually sits — and capital statecraft, when it is serious, spends downstream.
