Russia and China have blocked a United Nations Security Council resolution aimed at extending the mandate of experts monitoring sanctions against Iran, citing legal concerns. The resolution, which required an extension of the experts’ oversight of Iran’s nuclear program, was supported by 11 of the Council’s 15 members, while Russia and China exercised their veto power. Somalia and Pakistan chose to abstain from the vote.
The existing sanctions on Iran, including those targeting its assets, arms activities, and ballistic missile program, remain in place despite the veto. These sanctions were reinstated in September 2025 through the “snapback” mechanism of the 2015 Iran nuclear deal, which restored the UN’s sanctions framework and mandated expert monitoring to ensure compliance.
The United States, which proposed the resolution, argued that continued independent monitoring is crucial to document potential violations and strategies to circumvent sanctions. However, Russia challenged the legality of the snapback mechanism, claiming that it rendered the proposed extension of the experts’ mandate baseless. China also opposed the resolution, aligning with Russia’s stance.
This development occurs amid ongoing global apprehensions regarding Iran’s nuclear ambitions. The UN’s nuclear inspectors have encountered challenges in verifying Iran’s enriched uranium reserves, particularly following attacks on its nuclear facilities in 2025. The lack of an extended mandate for the expert panel raises questions about the future monitoring and reporting of Iran’s compliance with international sanctions to the Security Council.
