UN Security Council Members Clash Over Validity of Iran Sanctions and Committee Briefing

The UN Security Council experienced a significant clash among its permanent members during a briefing on the 1737 Sanctions Committee concerning Iran. Russia and China challenged the legal validity of the sanctions and the committee's continued functioning, arguing that Resolution 2231 (2015) expired in October 2025. The United States and the United Kingdom, however, asserted that the sanctions were reimposed in September 2025 via a "snapback" mechanism due to Iran's non-compliance with the nuclear deal, and the committee remains operational and mandated to report.
