Iran: Vote on a Draft Resolution*
Tomorrow morning (17 September), the Security Council is expected to vote on a draft resolution extending the mandate of the Panel of Experts (PoE) supporting the 1737 Iran Sanctions Committee for another year, until September 2027. The US authored the draft text.
The negotiations on the draft resolution reflected the difficult Council dynamics on the Iran file, which stem from disputes among Council members over the triggering of the “snapback” mechanism to reimpose the UN sanctions on Iran that the Joint Comprehensive Plan of Action (JCPOA) on Iran’s nuclear programme and resolution 2231 of 20 July 2015 had suspended. During the negotiations, China and Russia apparently reiterated their long-standing position, rejecting the legal and procedural validity of the triggering of the snapback mechanism. These two permanent members are therefore expected to vote against the draft resolution in blue, which will preclude its adoption even if the text receives nine or more positive votes.
Background
Resolution 2231 suspended all prior sanctions resolutions on Iran, rendering defunct the 1737 Committee—which was established through resolution 1737 of 23 December 2006—and its PoE. The Council originally established the Panel through resolution 1929 of 9 June 2010 and annually renewed its mandate, unlike the sanctions measures themselves, which were open-ended until resolution 2231 lifted them.
In August 2025, the “E3” parties to the JCPOA—France, Germany, and the UK—triggered the deal’s “snapback” mechanism to reimpose UN sanctions on Iran that the JCPOA and resolution 2231 had suspended. China and Russia contested the E3’s legal and procedural standing to do so and argued that all sanctions were permanently lifted on 18 October 2025, when the JCPOA and resolution 2231 were originally set to expire. On that date—absent an activation of the snapback—resolution 2231 stated that the Council would end its consideration of the Iranian nuclear file and “Non-Proliferation” would be removed from the list of matters of which the Council is seized.
By contrast, the E3 and like-minded Council members have argued that the triggering of the snapback mechanism was valid and therefore only specific paragraphs of resolution 2231 related to the suspension of sanctions have expired. As such, they maintain that all previous UN sanctions measures on Iran have been re-activated and that the 1737 Sanctions Committee and its PoE have been restored. These members believe that the Panel’s current mandate expires on 27 September.
The ongoing dispute among Council members on the 1737 Iran Sanctions Committee has stalled agreement on the allocation of subsidiary body chairs more than nine months into the year. Without a chair and unable to convene, the Committee has not been able to do any substantive work. In April, China and Russia also apparently rejected eight candidates proposed by the UN Secretariat to serve on the PoE.
Since the PoE has not been reconstituted, the only independent reporting on Iran’s nuclear programme is conducted by the International Atomic Energy Agency (IAEA), which also faces challenges in its monitoring and verification activities. On 10 September, the IAEA Board of Governors (BoG) adopted a new resolution calling on Iran to remedy its non-compliance with its Safeguards Agreement under the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). It requests IAEA Director General Rafael Mariano Grossi to report Iran to the UN Security Council and the General Assembly, marking the first time that the BoG has done so in 20 years. (For background and more information, see our 9 September What’s in Blue story.)
Difficult Council dynamics were on display during Council meetings on the Iranian nuclear programme convened in March, June, July, and September under the “Non-Proliferation” agenda item. At all four sessions, Russia requested a procedural vote on the agenda, which was adopted each time with 11 votes in favour, two against (China and Russia), and two abstentions (Pakistan and Somalia).
At the most recent such meeting, which was held on 10 September, China and Russia both signalled that they would continue to oppose efforts to revive the 1737 Committee. France and the UK called for the prompt appointment of a Committee chair and the reconstitution of the PoE, urging support for the Panel’s upcoming mandate renewal. Bahrain, Colombia, Latvia, and Liberia urged Council members to reach consensus on the Panel’s appointment. Greece expressed support for the draft resolution, while Denmark warned that the Panel’s mandate was due to expire this month absent Council action. Pakistan and Somalia, for their part, called for diplomacy to find common ground.
Negotiations on the Draft Resolution
The US circulated the zero draft of the resolution in late August and convened an initial read-through of the text on 31 August. During that meeting, China and Russia apparently reiterated their position that the snapback was invalid and that the JCPOA and resolution 2231 expired on 18 October 2025. These members apparently urged Council members to abandon the effort to renew the PoE’s mandate. It does not appear that any delegation submitted written comments on the text. Several members apparently felt that since the objections of China and Russia are rooted in the broader legal dispute over the snapback’s validity rather than in the wording of the draft itself, textual negotiations were largely moot. There was no further action on the text for several weeks, and on 15 September, the US proceeded to put the unchanged zero draft in blue, to be voted on tomorrow morning.
The operative section of the draft resolution in blue mostly makes technical updates to provisions contained in resolution 2224 of 9 June 2015, which last renewed the PoE’s mandate before the adoption of resolution 2231. Among other things, it extends the Panel’s mandate by one year and expresses the Council’s intention to review the mandate and take appropriate action regarding further extension no later than August 2027.
The US added some new language in the preambular section of the draft resolution in blue. For instance, it expresses the Council’s determination to adopt measures to persuade Iran to comply with relevant Security Council resolutions—including resolution 1929 and resolution 1737—and with the requirements of the IAEA. The draft resolution in blue also recalls the PoE’s reports and “the value of the credible, fact-based, independent assessments, analysis and recommendations provided to the Committee in support of the effective implementation of the measures imposed by relevant resolutions”.
At tomorrow’s vote, the draft resolution will fail to pass if it does not receive the requisite nine votes in favour or if at least one permanent member casts a negative vote. If the draft resolution were to garner nine favourable votes, China and Russia are likely to veto it. In line with the voting pattern on the procedural votes held during the Council’s meetings on the Iran nuclear file, Pakistan and Somalia may abstain. It was unclear at the time of writing whether any other Council members may abstain or vote against the draft resolution.
By contrast, the US, the Council’s European members (Denmark, France, Greece, Latvia, and the UK) and other like-minded members are expected to vote in favour of the text. It seems that some of these members have stressed the importance of securing at least nine votes in favour, viewing this threshold as a signal of the Council’s collective position on Iran’s non-compliance with its Safeguards Agreement, particularly against the backdrop of the recent IAEA BoG resolution on the matter.

*Post-script: On 17 September, the Security Council held a meeting under the “Non-Proliferation” agenda item to vote on a draft resolution extending the mandate of the Panel of Experts (PoE) supporting the 1737 Iran Sanctions Committee for another year, until September 2027. Prior to the meeting, Russia, supported by China, requested a procedural vote on the agenda. It was adopted with 11 votes in favour, two against (China and Russia), and two abstentions (Pakistan and Somalia). The draft resolution was subsequently put to a vote and received the same result. It was therefore not adopted due to the negative vote of two permanent members. (The veto applies only to substantive decisions and cannot be used to block procedural votes.)
