As recently as last week, the UN Security Council held an open briefing on the work of the  UN 1737 Sanctions Committee, established in 2006 to monitor Iran's nuclear activities. Russia and China objected to the session, arguing that the snapback was never validly triggered and that the sanctions committee no longer exists. The Council voted 11-2 to proceed.

Some quick background: In 2015, Iran and several world powers reached a nuclear deal known as the Joint Comprehensive Plan of Action (JCPOA). The UN Security Council endorsed the deal through Resolution 2231 (2015), which lifted previous sanctions in exchange for limits on Iran's nuclear program. The resolution included a "snapback" mechanism, which was essentially a way to automatically reimpose sanctions if Iran wasn't meeting its commitments. In August 2025, France, Germany, and the UK invoked it, and the sanctions returned.
