Security Council Warned Iran Nuclear Stalemate Is Creating Oversight Vacuum
The Security Council’s permanent members remained split today over whether UN sanctions related to Iran’s nuclear programme are still in force, as Liberia —— one of the Council’s 10 elected members — called for the establishment of a Secretariat-led temporary reporting mechanism to address what it described as an oversight gap.
This division comes amid sharply escalating regional tensions following military strikes on Iran by Israel and the United States and Iran’s counterattacks against its neighbours.
At stake is the 2015 Iran nuclear agreement — officially known as the Joint Comprehensive Plan of Action and agreed by Iran, China, France, Germany, Russian Federation, United Kingdom, United States and the European Union — as well as the “snapback” mechanism built in Council resolution 2231 (2015), which endorsed the agreement and established a 10-year UN framework for its implementation. Under the deal, Iran accepted limits and monitoring on its nuclear programme in exchange for sanctions relief.
The agreement followed years of international concern over Iran’s nuclear programme and a series of Council resolutions adopted from 2006 onward requiring Tehran to suspend uranium enrichment and cooperate with International Atomic Energy Agency (IAEA) inspectors. Those included resolution 1737 (2006), which established the Committee concerning Iran.
With the 10-year framework under resolution 2231 (2015) due to expire in October 2025, France, Germany and the United Kingdom triggered the “snapback” mechanism in August 2025, citing Iran’s alleged non-performance of its commitments. The mechanism was designed to restore previously lifted UN sanctions unless the Council adopted a resolution to continue sanctions relief.
On 19 September 2025, the Council failed to adopt such a resolution. A later attempt that month also failed. As a result, according to the UN Secretariat, previously lifted UN sanctions against Iran were reapplied on 27 September 2025. The website of the 1737 Committee and the related Sanctions List were also reinstated.
Debate over ‘Snapback’ Mechanism
Objecting to a recent Council meeting concerning that Committee, the Russian Federation and China held that the “snapback” mechanism had not been activated. Meanwhile, France, United Kingdom and the United States declared that this mechanism had indeed been triggered, and therefore, that sanctions on Iran have been reinstated. These divisions played out again today.
Before today’s meeting began, the representative of the Russian Federation stated that the “snapback” mechanism was not triggered “for a range of reasons”, and neither “deliberate distortions” nor the “erroneous and unlawful position of the UN Secretariat leadership are of any relevance here”. Stressing that there are — and will be — no grounds for holding a 1737 Committee briefing, he requested that the Council vote on the question of holding today’s meeting.
He was joined on that by China’s representative, who added that the Council “has never reached a consensus” on the invocation of the “snapback” mechanism. “The Council has concluded its consideration of the Iranian nuclear issue,” he said, and he urged members to implement the measures related to the termination of this sanctions regime pursuant to resolution 2231 (2015), uphold the Council’s authority and “create favourable conditions for the political settlement of the Iranian nuclear issue”.
However, the representatives of France and the United Kingdom said that today’s meeting accords with previous Council decisions, as the “snapback” procedure was triggered pursuant to resolution 1737 (2006). The Council should therefore not be prevented from discussing these matters, and the representative of the United States added concern that obstruction from two Council members is blocking the delivery of the 1737 Committee’s 90-day report.
The Council then voted to adopt the provisional agenda and hold the meeting by a recorded vote of 11 in favour to 2 against (China, Russian Federation), with 2 abstentions (Pakistan, Somalia).
During the debate that followed, these positions were expressed again alongside calls for dialogue and restraint, as well as support for the nuclear non-proliferation regime.
Liberia Proposes Stop-Gap Measures
“We face a moment of dual crisis: a region holding a fragile ceasefire and a Council that has allowed competing legal interpretations to displace collective responsibility,” observed Liberia’s representative. Warning of the cost when the Council “allows procedural disagreement to become a substitute for action”, he underscored that the impasse over the 1737 Committee is the organ’s “most immediate institutional challenge” that creates a vacuum in oversight precisely when it matters most.
He therefore urged three “necessary and achievable” steps. The Council should request that the Secretary-General establish interim Secretariat-led reporting arrangements, facilitate a dedicated communication channel between the relevant parties and facilitate a time-bound negotiating process to address nuclear concerns and regional security issues in parallel. He underscored that, while the Council cannot always eliminate disagreement, “it must never allow disagreement to eliminate action”.
Council’s Ability to Act ‘Impacted’
Stressing that the Council’s non-proliferation goals can only be achieved through “effective verification and monitoring mechanisms”, Panama’s representative said that bodies created for this purpose — including the 1737 Committee — “must be able to carry out their mandates”. He also underlined the need for the Council to have access to expert analysis based on evidence and verified, current information so that the organ can “precisely evaluate current challenges”.
The representative of Colombia, Council President for June, spoke in his national capacity to agree on the need to preserve the technical integrity and effective functioning of the Council’s subsidiary bodies, including the 1737 Committee. Expressing regret over the persistent difficulties that have prevented that Committee’s regular operation, he stressed that this has impacted the Council’s ability to act effectively. Similarly, the representative of the Democratic Republic of the Congo said that the alternative arrangement currently in place “cannot meet the demands of effective operation in the long term”.
Concern over Iran’s Attacks against Gulf Countries
Underlining the stakes was Bahrain’s representative, who said that the targeting of sensitive facilities in her country and the United Arab Emirates demonstrate “systemic behaviour that poses a daily threat to regional security and stability”. Further, Iran’s resumed missile attacks against Bahrain and Kuwait are part of a repeated, ongoing pattern that endangers civilians and undermines trust in UN non-proliferation and sanctions regimes. She therefore stressed the importance of continuing the 1737 Committee’s work, “which is an essential tool for guaranteeing respect for related obligations”.
France’s representative also pointed to the importance of that Committee’s work, especially “at a time when the Iranian nuclear programme continues to raise serious security concerns, and when the Iranian authorities continue to be ambiguous about their intentions”. Greece’s representative, stating that the reinstatement of the 1737 Committee was both “valid and legitimate”, emphasized that — in the absence of a negotiated solution — the body is an essential mechanism for ensuring Iran’s compliance with UN sanctions.
The representative of the United Kingdom, in that vein, said that the international community needs clarity and reassurance regarding the peaceful nature of Iran’s nuclear programme. “Iran must never be allowed to develop or acquire a nuclear weapon,” declared Denmark’s representative, adding that “the current escalation clearly demonstrates why this is so important”. She expressed regret over some Council members’ inability to “recognize the reality that all sanctions against Iran were reimposed last year”. Latvia’s representative also expressed regret that “some Council members continue to dispute legal reality”.
Calls for Moscow, Beijing Not to Block ‘Possibility of Peace’
More pointedly, the representative of the United States said that “Russia and China have sought to neutralize this Committee, render Iran a beholden partner and divert international attention away from their own non-compliance”. To view these mechanisms as punitive is a wilful misunderstanding of the Council and its tools, as they provide the Council with a peaceful means of resolving threats to international security. She urged Moscow and Beijing to stop subverting Council decisions, and “more fundamentally, not obstruct the possibility of peace”.
However, China’s representative said that the root cause of the current difficulty is that the United States has undermined diplomatic efforts. Stressing the need to “abandon power politics”, he said that the Council has terminated consideration of the Iranian nuclear issue. And noting the fragile ceasefire in place between Iran and the United States, he called on the Council to stand on “the right side of history” and act with caution.
Russian Federation: Iran Nuclear Issue No Longer on Council’s Agenda
Meanwhile, the representative of the Russian Federation expressed regret that most Council members “continue to indulge the legal and procedural nihilism of Western States”. Their true objective, he said, is to create the illusion that the Committee has resumed its work and “trample upon the legal and procedural foundation” of the Council’s functioning to pressure Iran. “No matter how much our Western colleagues might try to persuade us otherwise, reality is unrelenting,” he stressed, adding: “The Council has concluded its consideration of the Iranian nuclear issue.”
Noting “divergent views” among Council members regarding the 1737 Committee, Somalia’s representative said that the “only viable path forward” is sustained, substantive talks on non-proliferation anchored in relevant Council resolutions. Pakistan’s representative similarly underlined the importance of dialogue, noting his country’s diplomatic initiatives to bring the parties to the negotiating table in Islamabad. “Give peace a little more chance,” he urged.
