Kazakhstan’s new uranium law rewards partners that build processing plants on its soil, a model that favors China and leaves Washington with few options.

This month Kazatomprom approved a uranium supply contract with a Chinese state buyer and refused a near-identical one with Russia’s Rosatom. The Chinese shipment was routed to the Alashankou crossing on the Chinese border; the Russian one would have gone to the Siberian Chemical Plant inside Russia. From the outside it looks like a choice between two customers. It is better read as one move in a design Kazakhstan has spent more than a year drafting, whose terms now favor China for reasons that owe little to friendship and much to law.

The vote matters because of whose vote it is. Kazakhstan has been the world’s leading uranium producer since 2009 and mined close to 40 percent of global supply in 2025. When a supplier of that weight reorders its foreign partnerships, the entire fuel market moves with it. For Washington, which is trying to rebuild a nuclear-fuel supply chain that does not run through Russia, the direction of the reordering is what should register.

How Kazakhstan’s New Uranium Law Works

In late December 2025, President Kassym-Jomart Tokayev signed amendments to the Subsoil Use Code that rewrote the terms on which foreigners may own Kazakh uranium. New production licenses can now be transferred only to entities in which Kazatomprom holds more than 75 percent, up from half. Extending a mine’s life, or lifting its output beyond approved levels, requires Kazatomprom to own at least 90 percent of the venture. Further exploration at producing deposits is reserved for the national company. The design is resource nationalism, not alignment. Astana wants the asset in its own hands, not passed to a new foreign patron.
