UK Regrets Veto on Iran Panel of Experts Mandate Renewal

For over twenty years, the international community has sought to address the threat posed by Iran’s nuclear and missile programmes. The United Kingdom has consistently championed a diplomatic solution. Regrettably, Iran has too often chosen escalation over cooperation, creating the circumstances that continue to demand the Council’s attention today: expanding her nuclear programme in ways that lack any credible civilian justification; failing to cooperate with the IAEA and denying access to IAEA inspectors; meaning that the IAEA has been unable to verify the current size, composition, or whereabouts of Iran’s enriched uranium stockpile. This Council established the 1737 Iran sanctions committee in 2006 because of these grave concerns, and established a Panel of Experts in 2010 to help the committee monitor the relevant provisions and to provide expert and independent advice to ensure that sanctions were effective and appropriate.

Background
The 1737 Iran sanctions committee was established in 2006 in response to concerns regarding Iran’s nuclear programme. The Panel of Experts, established in 2010, was designed to monitor the implementation of these sanctions and offer independent advice. Twenty years later, we are again dealing with an Iran that refuses to comply with its basic legal requirements of legitimate civil nuclear activity. Russia and China voted for both these resolutions. In March 2024, Russia’s veto of the 1718 Panel of Experts ended 14 years of monitoring expertise on the DPRK’s sanctions evasion.

Analysis
The United Kingdom regrets that Russia and China have chosen to exercise their veto today, choosing to shield Iran and to undermine this Council’s work to ensure that she doesn’t acquire a nuclear weapon. The statement does not address the ongoing concerns surrounding Iran’s nuclear activities. If implemented as described, the Panel of Experts’ mandate was intended to provide a crucial layer of scrutiny and accountability. The statement does not address the implications of Russia’s actions regarding sanctions evasion, particularly concerning the DPRK.

Implications
The United Kingdom stands ready to work with all partners towards a negotiated settlement, to uphold and strengthen the global non-proliferation regime, and to ensure that Iran never acquires or develops a nuclear weapon. Sanctions against Iranian proliferation remain fully in force, binding on each and every UN Member State. Should the visit yield no change in Iranian behaviour, the UK will continue to maintain the sanctions.

Outlook
If Russia and China continue to use their veto power to obstruct Council action, the UK will continue to pursue alternative avenues for ensuring sanctions effectiveness. Should the situation remain unchanged, the UK will reassess its approach to engagement with Iran, prioritizing the global non-proliferation regime and the security of international peace and security.

Conclusion
The UK’s regret underscores a fundamental disagreement with Russia and China regarding the urgency of addressing Iran’s actions, a disagreement that will likely shape the Council’s future deliberations on this critical issue.
