Could the war in Iran end with Tehran’s uranium in Chinese coffers?

When U.S. and Iranian negotiators began sketching out the contours of a ceasefire framework, the central verification problem was always the same: Where is the uranium going? In 2015, the answer was Russia.

Tehran shipped its excess enriched stockpiles to Moscow under the Joint Comprehensive Plan of Action (JCPOA) agreements that relied, however imperfectly, on an infrastructure of Cold War-era arms control diplomacy between Washington and the Kremlin.

This infrastructure no longer exists. Furthermore, reports from the current round of negotiations suggest that Tehran is now considering something much more substantial: transferring its stockpile of 60% enriched uranium to China.

If this proposal moves forward, the United States will not just manage the Iranian nuclear problem. She will inherit a Sino-American verification crisis without an institutional framework, without precedent and without a clear resolution.

The geopolitical logic underlying this proposition is simple. Russia is no longer a viable goalkeeper. After Ukraine, Washington cannot ask Moscow to hold equipment that it has sanctioned and isolated for three years. The political optics alone would be unworkable for any U.S. administration.

China, on the other hand, presents itself as a neutral facilitator. Beijing has positioned itself throughout Iran’s nuclear issue as a responsible stakeholder, and it has the physical infrastructure, diplomatic relations with Tehran, and incentives necessary to prevent a full-scale regional war that would destabilize its energy supply chains. From a purely transactional point of view, the proposition has logic.

But the logic evaporates as soon as we ask the following question: how can we verify what happens to this material once it enters Chinese custody?

The United States and China do not have a mature bilateral nuclear inspection architecture. The Open Skies Treaty is obsolete. New START was a US-Russian instrument. The Intermediate-Range Nuclear Forces Treaty is dead. The mechanisms that allowed American and Soviet – and later Russian – inspectors to physically enter each other’s nuclear facilities, count nuclear warheads and verify dismantling, simply do not exist between Washington and Beijing.

What exists instead is a relationship defined by technological competition, semiconductor export controls, accusations of intellectual property theft, and a mutual intelligence posture that treats any intrusive access as a potential vector for espionage.

This creates a verification void at the heart of any deal that moves Iranian uranium through Chinese territory. The International Atomic Energy Agency (IAEA) could theoretically monitor transfer and initial storage, but the IAEA’s authority depends on the cooperation of the host state, and China has never authorized the type of challenge inspections that would be necessary to verify the long-term disposal of weapons-grade materials.

The dilution can be reversed. Containment can be compartmentalized. Without a right of return, without continuous monitoring and without the possibility of carrying out rapid inspections of Chinese nuclear installations, any American assurance regarding the neutralization of these materials would rely solely on Beijing’s word.

Western intelligence agencies face a compounding problem. Any attempt to independently verify Iranian uranium stored in China risks triggering exactly the kind of incident that would derail the broader diplomatic framework.

If U.S. or Israeli signals intelligence begins actively penetrating China’s nuclear storage sites to check the chain of custody, Beijing will label them as espionage against its sovereign nuclear infrastructure. The same facilities that could contain Iranian enriched uranium are likely adjacent to China’s military nuclear programs. Geographic overlap transforms a nonproliferation monitoring operation into a technological and intelligence confrontation between two nuclear powers.

Israel’s position in this scenario is perhaps the most strategically uncomfortable. For years, Israeli policymakers and the pro-Israel political community at large have argued that the Iranian nuclear issue is primarily an Israeli existential problem dressed up in the guise of international diplomacy. If a deal is reached to transfer Iranian weapons-grade uranium to China, Israel will be asked to accept a framework in which its most acute security threat is theoretically defused, but the material enabling that threat is held by a power with which Israel has significant economic ties, diplomatic complexities, and no binding security relationship. The dissuasive calculation does not disappear; it migrates from the Middle East to the triangular geometry of relations between the United States, China and Israel.

There is also the question of what Beijing really wants. China has never been a disinterested actor in Iran’s nuclear diplomacy. Storing Iranian enriched uranium gives Beijing leverage over Tehran, leverage over Washington and a permanent seat at any future table where the Iranian nuclear file is reopened. This transforms a bilateral nonproliferation issue into a trilateral great-power asset. This is not a verification solution. This is a strategic acquisition.

The Biden-era revival of the JCPOA failed in part because of disputes over verification language. The current ceasefire framework should not repeat this mistake by handing the verification problem to a power that has no obligation to resolve it. Sending Iranian uranium to China does not end the nuclear crisis. He relocates it to an address where American inspectors are not welcome.
