SAEDNEWS: In a joint letter, Iran, Russia, and China announced that all provisions of UN Resolution 2231 will expire on October 18, 2025, ending the Security Council’s review of Iran’s nuclear file and boosting multilateral diplomacy.
According to SaedNews’ political desk, a joint letter from the ambassadors of Iran, Russia, and China to the United Nations states:
“We are honored to refer to the joint letter of the Foreign Ministers of the People’s Republic of China, the Islamic Republic of Iran, and the Russian Federation, dated August 28, 2025, distributed in both the UN Security Council and General Assembly. The letter outlines our countries’ unified position regarding recent actions by the United Kingdom, France, and Germany, which claim to have acted under the framework of Security Council Resolution 2231 (2015).”
The three countries emphasized: “We reiterate that the attempt by the three European nations to trigger the so-called ‘snapback mechanism’ is fundamentally flawed both legally and procedurally. These European states, having failed to fulfill their obligations under the JCPOA and Resolution 2231, and without following the established ‘dispute resolution mechanism,’ lack any legitimacy to invoke its provisions.”
In their joint statement, Iran, Russia, and China clarified: “Under the operational clause 8 of Resolution 2231, all provisions of the resolution will terminate after October 18, 2025. We reaffirm that the full and timely expiration of Resolution 2231 marks the end of the Security Council’s review of Iran’s nuclear issue—a development that strengthens the authority of the Council and the credibility of multilateral diplomacy.”
The letter further stressed: “It is essential that all relevant parties remain committed to finding a political solution through diplomatic engagement and dialogue based on mutual respect, addressing the concerns of all sides. They must refrain from unilateral sanctions, threats of force, or any actions that escalate tensions. Moreover, all countries should contribute to fostering a favorable environment for continued diplomatic efforts.”
Iran, Russia, and China requested that their letter be officially published as a UN Security Council document, addressed to Secretary-General António Guterres and the current Council President (Russia, in October).
The Iranian Ministry of Foreign Affairs also confirmed the expiration of UN Security Council Resolution 2231, stating: “As previously noted in official statements regarding the JCPOA and Resolution 2231 of July 20, 2015, the ten-year period specified by the resolution ends on Saturday, October 18, 2025. From this date, all provisions—including restrictions on Iran’s nuclear program and associated mechanisms—will be considered terminated.”
Consequently, the nuclear issue, which has been under the Council’s ‘non-proliferation’ agenda, should be removed from the Security Council’s active considerations. Following the expiration of Resolution 2231, Iran’s nuclear program will be treated like that of any non-nuclear-weapon state party to the Non-Proliferation Treaty.
