Russia and China veto UN mandate to monitor Iran sanctions

Russia and China vetoed a U.S.-drafted UN Security Council resolution on September 17, 2026, ending the mandate of an independent panel of experts monitoring sanctions on Iran. The 11-2 vote, with Pakistan and Somalia abstaining, highlights deep geopolitical divisions. The vetoes occur amid an ongoing war between the U.S., Israel, and Iran, and follow reports that Iran maintains 440.9 kilograms of 60% enriched uranium while blocking UN nuclear inspectors from accessing its facilities.
