Iran, Russia, and China have formally addressed the International Atomic Energy Agency (IAEA) regarding the expiration of UN Security Council Resolution 2231 on October 18, 2025, which ended the IAEA’s oversight of Iran’s nuclear activities. Their joint letter, sent on October 30, 2025, opposes the European “snapback” sanctions, asserting they lack legal basis due to the E3’s prior violations of the Joint Comprehensive Plan of Action (JCPOA). The three nations advocate for diplomacy and dialogue over unilateral actions, emphasizing the need for mutual respect and cooperation to address nuclear concerns and prevent escalating tensions.
