Russia and China have blocked a US-drafted resolution at the UN Security Council seeking to extend independent monitoring of sanctions imposed on Iran over its nuclear programme, exposing a fresh divide among major powers over the legal status of the sanctions regime. The resolution secured 11 votes in favour, but the vetoes by Moscow and Beijing prevented its adoption, while Pakistan and Somalia abstained.
The United Nations Security Council has been plunged into another dispute over Iran after Russia and China vetoed a US-drafted resolution designed to keep an expert mechanism monitoring the implementation of UN sanctions against Tehran.
The proposal received 11 votes in favour, while Russia and China voted against it. Pakistan and Somalia abstained. Although the measure enjoyed majority support, the vetoes by two permanent members were enough to prevent its adoption.
The immediate consequence is the end of the proposed continuation of the independent expert-monitoring mechanism. The sanctions themselves, however, remain in place. The vote therefore concerns the monitoring and reporting structure rather than the automatic removal of the sanctions regime.
The confrontation reflects a deeper disagreement over the legal basis of the sanctions restored against Iran in 2025.
France, Germany and Britain invoked the so-called “snapback” mechanism under the 2015 Iran nuclear agreement, leading to the restoration of earlier UN sanctions. Western countries maintain that the procedure was valid and that the sanctions framework remains legally applicable.
Russia and China reject that interpretation. Moscow has argued that the relevant Security Council framework associated with the 2015 nuclear agreement expired in October 2025 and that the subsequent sanctions process therefore lacks a valid legal foundation. China has expressed a similar position, saying the Council should focus on diplomacy rather than continue what it considers an expired framework.
Russia's UN ambassador Vasily Nebenzia described the US-backed proposal as legally flawed. Moscow and Beijing had also urged the United States and its allies not to proceed with the vote, arguing that doing so would deepen divisions within the Council.
The United States defended the proposed extension on the grounds that an independent panel was necessary to document possible violations of the sanctions regime.
US officials argued that without such experts, the Security Council would lose an important source of independent reporting on suspected sanctions violations. Washington has also pointed to previous cases in which disagreements among permanent members resulted in the disappearance or weakening of UN expert-monitoring arrangements.
The latest dispute follows the earlier breakdown of the UN expert mechanism monitoring sanctions on North Korea, after Russia vetoed its continuation in 2024.
Iran welcomed the Russian and Chinese votes, thanking both countries for blocking the American initiative. Tehran has consistently rejected allegations that its nuclear programme is intended to produce nuclear weapons.
The dispute nevertheless comes against the backdrop of continuing international concern over Iran's enrichment activities and the ability of the International Atomic Energy Agency (IAEA) to independently verify developments inside the country.
The IAEA has previously reported significant quantities of uranium enriched to 60 per cent, well above the enrichment level permitted for civilian nuclear power under the 2015 agreement. Questions over access, verification and the status of Iran's nuclear material have remained central to the wider diplomatic dispute.
Another important element of the controversy is that the expert panel had not been functioning at full capacity. Although the UN Secretary-General had proposed experts, the Security Council did not complete the appointment process, leaving the monitoring mechanism without a fully operational panel for an extended period. Reuters reported that the panel had effectively remained inactive because of disagreements over appointments.
The latest veto therefore prevents a further extension rather than shutting down a monitoring body that had been conducting regular operations.
