Security Council Warned Deadlock on Iran Nuclear Issue Creates Oversight Vacuum

(A full summary of the meeting will be published on 10 June.)

The Security Council's permanent members remained split today over whether UN sanctions on Iran's nuclear programme are still in force, with Liberia - one of the 10 non-permanent members - warning that this dispute is creating a gap in oversight and calling for the establishment of a Secretariat-led temporary reporting mechanism.

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.

On 19 September 2025, the Council failed to adopt a resolution that would have continued UN sanctions relief as contemplated by the Joint Comprehensive Plan of Action. This occurred after France, Germany and the United Kingdom triggered the process to reimpose sanctions on Iran - often referred to as a "snapback" mechanism - over Tehran's alleged non-performance of its obligations under the Plan.

Later that month, the Council again failed to adopt a similar resolution. At a briefing on 23 December 2025, the organ was informed by a senior UN official that, as a result, previously lifted UN sanctions against Iran were reapplied on 27 September 2025. That included the reinstatement of the website of the Security Council Committee established pursuant to resolution 1737 (2006) concerning Iran, as well as the related sanctions list.

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, the 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 the 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.

"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".
