The search for a storage site follows the rejection of Russia and China by U.S. President Donald Trump, who has publicly opposed their involvement in managing the material. Conversely, Iran has categorically ruled out transferring the stockpile to the United States, viewing the material as critical leverage. Kazakhstan, which already hosts an IAEA-owned low-enriched uranium bank, is positioning itself as a neutral ground. Foreign Ministry spokesman Aibek Smadiyarov confirmed Astana’s willingness to provide technical assistance, provided all parties finalize the necessary international agreements.

However, the logistical and political challenges are significant. Ali Vaez of the International Crisis Group warns that for Iran, the primary concern is the guaranteed repatriation of the material should the U.S. renege on future commitments. Furthermore, the storage of 60-percent enriched uranium requires far more stringent security protocols than the civilian-grade materials currently held at the Ulba Metallurgical Plant in Oskemen. Environmental experts in the region note that local residents, already grappling with severe industrial pollution and elevated health concerns, remain wary of hosting such a volatile stockpile. While Kazakhstan’s history as a nonproliferation advocate—highlighted by the 1994 Project Sapphire—lends credibility to the bid, the nation must now navigate a narrow path between its desire for international mediation and the volatile realities of global nuclear diplomacy.
