Iran, Russia, and China Announce Termination of UN Oversight on Nuclear Deal

In a significant development regarding international nuclear oversight, the permanent representatives of Iran, Russia, and China have communicated with the International Atomic Energy Agency (IAEA) about the expiration of UN Security Council Resolution 2231. This resolution, which was originally adopted in 2015, officially lapsed on October 18, 2025, leading to the termination of the IAEA’s mandate to report on Iran’s nuclear activities. This article delves into the implications of this communication and the ongoing geopolitical tensions surrounding the nuclear issue.

The joint letter addressed to IAEA Director General Rafael Grossi emphasizes the trio’s opposition to the European “snapback” initiative, which they consider to be legally unfounded. The representatives strongly advocate for dialogue and diplomatic approaches rather than unilateral actions. Below are key points from the letter:

• The joint communication was submitted on October 30, 2025, highlighting the expiration of Security Council Resolution 2231.
• The letter requests the circulation of their communication as an official document of the Security Council.
• The three countries reaffirm their position against the snapback mechanism invoked by the European trio (E3) – the United Kingdom, France, and Germany.
• They argue that the E3 lacks the legal standing to invoke the snapback due to their previous violations of the Joint Comprehensive Plan of Action (JCPOA) and Resolution 2231.
• The expiration of Resolution 2231 means the IAEA’s reporting mandate has lapsed as of October 18, 2025.

The letter, signed by Saeed Iravani (Iran), Fu Cong (China), and Vassily Nebenzia (Russia), outlines their collective stance against unilateral sanctions and emphasizes the need for a political resolution through diplomacy. They advocate for mutual respect and cooperation among all nations involved in the dialogue surrounding nuclear activities.

In their communication, the ambassadors refer back to a previous joint letter from August 28, 2025, which addressed actions taken by the E3 regarding Resolution 2231. They reiterate:

1. The E3’s invocation of the snapback is procedurally flawed.
2. The E3 has themselves violated commitments under the JCPOA and Resolution 2231.
3. They have not exhausted the Dispute Resolution Mechanism (DRM), undermining their position.

These points collectively contribute to the assertion that all provisions of UNSCR 2231 were effectively terminated on the specified date, leading to the cessation of the IAEA’s reporting obligations. According to the letter, the Board of Governors of the IAEA had previously established that their mandate would remain until ten years after the JCPOA’s Adoption Day or until the IAEA reached a broader conclusion regarding Iran’s nuclear activities. As of now, with the expiration of Resolution 2231, this agenda item has been removed from further consideration.

The three nations underline the importance of maintaining diplomatic engagement to address mutual concerns and to prevent any actions that could escalate tensions. They call for:

• A commitment to finding a political settlement through dialogue.
• Avoidance of unilateral sanctions and threats of force.
• Contributions from all countries to foster a conducive environment for diplomacy.

In conclusion, the joint letter from Iran, Russia, and China represents a pivotal moment in the ongoing discourse surrounding Iran’s nuclear program and the broader implications for international relations. As the IAEA moves forward without the mandate of Resolution 2231, the call for diplomacy and dialogue becomes even more crucial in navigating the complexities of nuclear governance.

It is the hope of the permanent missions of these three countries that their communication will be circulated among all IAEA member states, fostering greater understanding and cooperation in addressing the sensitive nuclear issues at hand.
