UN Security Council debates legality of Iran sanctions snapback

The five permanent members of the United Nations Security Council engaged in intense debate on Thursday regarding the legal validity of international sanctions against Iran. The discussion centered on the ‘snapback’ mechanism established under the 2015 Joint Comprehensive Plan of Action (JCPOA).

Russia and China have opposed the reimposition of UN sanctions, arguing that the legal basis for such actions has expired. Russian diplomats stated that the mechanism to reinstate previous Security Council resolutions, as outlined in Resolution 2231, has not been activated due to legal and procedural reasons. Moscow maintains that Resolution 2231 expired on October 18, 2025, and that the non-proliferation agenda was removed from the council's active list as of that date.

China supported Russia's position, warning against unilateral actions and asserting that certain members are attempting to force the reimposition of sanctions by holding meetings on agendas that have already been removed. The dispute follows Iran's increased uranium enrichment, a move it claims was a response to the United States withdrawing from the JCPOA under the first Trump administration and subsequently reimposing economic sanctions.
