Security Council
Non-proliferation - Security Council, 10224th meeting
The Security Council today failed to adopt a resolution that would have extended the mandate of the Panel of Experts tasked with monitoring implementation of United Nations sanctions on Iran, as Council members continued to be divided on whether those sanctions are in force at all.
In 2015, the Council endorsed the Joint Comprehensive Plan of Action — which provided sanctions relief to Iran in exchange for a 10-year monitoring framework and limits to its nuclear programme — when it adopted resolution 2231 (2015). That text also provided for a “snapback” mechanism, by which UN sanctions would automatically be reinstated in the event of non-compliance. In May 2018, the United States withdrew from the Plan; Iran retaliated by reducing its commitments.
In September 2025 — shortly before the expiry of the 10-year framework — Plan signatories France, Germany and the United Kingdom cited Tehran’s alleged non-compliance and held that the “snapback” mechanism had been triggered. As the Council failed to adopt a resolution to continue sanctions relief, it was informed by the UN Secretariat that previously lifted UN sanctions were re-applied on 27 September 2025. This would also restore the Council Committee established pursuant to resolution 1737 (2006) to report on Iran’s nuclear programme.
