Russia and China kill UN Iran watchdog as sanctions dispute deepens

• Russia and China vetoed a US-backed resolution to renew UN experts’ mandate for monitoring sanctions on Iran. Eleven council members supported it; Pakistan and Somalia abstained. ¹
• The veto blocks the monitoring mechanism, not the sanctions themselves. The measures — including asset freezes, arms restrictions and penalties linked to Iran’s ballistic-missile programme — remain in force under the US, British and French interpretation of the law. ²
• The sanctions’ legal status is itself disputed. Russia and China say the “snapback” process that restored them was invalid and that the underlying UN framework expired on 18 October 2025. ³
• The expert panel had been authorised but never fully appointed, meaning the council was already operating without the independent investigators meant to document violations. ²
• A replacement could be built outside the Security Council, potentially by France, Germany, Britain and the United States, but it would not carry the same UN authority. ²

The immediate consequence is a reporting vacuum. States are still expected to enforce the sanctions under the Western reading of the resolutions, but the UN body designed to gather evidence, identify evasion networks and recommend action is gone. The International Atomic Energy Agency also says it has lost continuity of knowledge about parts of Iran’s nuclear programme after access and verification work broke down. ³

That leaves enforcement dependent on national intelligence and political alliances at the very moment Washington and Tehran are at war and President Donald Trump is preparing to meet China’s Xi Jinping. Russia and China have not removed the sanctions; they have used their veto to stop the UN from independently testing claims about who is breaking them. A coalition monitoring team is possible, as happened after Russia blocked a similar panel on North Korea, but it would be a workaround rather than a functioning Security Council mechanism. ²
