In one year, China built approximately a third of the USA’s entire enrichment capacity and nobody has noticed.
Boundless Discovery discovered a new hall appeared on the ground at Lanzhou. China is expanding enrichment in step with its reactor build-out, holding to a long-standing policy of fuel-cycle self-sufficiency. It makes its own enriched uranium and depends on no one for it.
Set that against the trade data.
In 2025, China imported 758 more tons of Russian enriched uranium than the year before. That single-year increase approaches the entire annual fuel demand of France's 57-reactor fleet. Record volumes of a material China is already self-sufficient in.
So the question is why.
Russia holds >40% of world enrichment capacity and is losing access to the US and UK markets to sanctions. The EU still buys, because it has no alternative. China buys because it chooses to, at prices increasingly depressed by Russia's shrinking pool of buyers. It runs that cheap material through its own reactors and into its stockpile.
Here is what that positions China to do.
Cheap Russian supply covering domestic demand frees China's own clean-origin enrichment to sell abroad. The US, meanwhile, walks into a real shortfall: domestic capacity near 4.3M SWU against a fleet needing ~13M, and no more Russian supply after 2028. Prices there will be high. And those high prices are integral to the Western rebuild because that private capital only commits against contracts priced to hold for years.
A supplier sitting on cheap feed and surplus capacity can undercut exactly when it chooses. Offer low into a tight US market, and the new Western plants never get the price signal they need to continue to scale profitably. Short-term relief becomes long-term dependency. Then the leverage sits with whoever holds the valve.
We have seen this sequence before, in rare earths. China builds self-sufficiency, corners the processing chokepoint, and stockpiles the input. Then set the terms for everyone else. Enrichment is a key processing chokepoint of the nuclear fuel cycle. The uranium story is early in the same script.
None of this has happened yet. China is buying, building, and stockpiling. That is all observable. The rest is what the position makes possible, and it is not currently priced.
