Russia, China Veto UN Watchdog Over Iran Sanctions

The United Nations Security Council in New York failed on Thursday evening to extend the mandate of an independent panel of experts monitoring the enforcement of sanctions on Iran, after Russia and China vetoed a draft resolution drawn up by the United States. Eleven of the Council’s 15 members voted for the text, Pakistan and Somalia abstained, and the veto of two permanent members was enough to sink the decision regardless of the majority. The vote took place thousands of kilometers from Belgrade, yet its outcome touches directly on the question that has mattered most to Serbia at the Security Council for decades: how enforceable the body’s decisions really are once permanent members decide to block them. The same veto logic that shut down oversight of Iran on Thursday also underpins every debate about Kosovo and Resolution 1244, so a precedent set in one sanctions regime carries weight in others.

What the Security Council Voted On

The draft resolution would have extended for another year the mandate of the independent panel that reports on violations of the sanctions imposed on Iran over its nuclear program. The panel was renewed in 2025, but its experts were never appointed because Council members could not agree on candidates: in April, Russia and China rejected all eight names proposed by the UN Secretariat. As a result, the sanctions committee has been without a chair for more than nine months and is effectively not functioning.

Russia’s ambassador to the UN, Vasily Nebenzya, said the draft had no legal basis and that Moscow and Beijing had warned Washington in advance that the vote would bring nothing good.

“We strongly urged the authors to abandon pushing such a draft, it was clear that the only thing such a persistent push for that text could bring is further growth of tensions inside the Security Council, both politically and procedurally,” Nebenzya said at the Security Council.

The Russian ambassador also had a direct message for Western members:

“We strongly call on our Western colleagues to halt their very dangerous moves on the Iranian front, which threaten to further complicate the resolution of the crisis in the Persian Gulf,” Nebenzya said.

China’s UN ambassador, Fu Cong, called on Council members to avoid “double standards, political manipulation, pressure and confrontation.” Iran’s mission to the UN said in a social media post after the vote that “Iran deeply appreciates Russia and China for their consistent and principled positions and resolute actions today.”

Why Oversight Stopped Existing in the First Place

The sanctions in question are not new: they were reimposed on September 27, 2025, through the so-called snapback mechanism under the 2015 nuclear deal, triggered by France, Germany and the United Kingdom back in August of that year. That restored six earlier Security Council resolutions that freeze Iranian assets abroad, restrict arms sales to Tehran and target its ballistic missile program. Thursday’s vote does not lift the sanctions themselves, which remain formally in force, but from now on no one at the United Nations is monitoring whether they are actually being enforced.

The deputy US ambassador to the UN, Jennifer Loseta, warned that this opens the door to abuse.

“Without an independent panel of experts, this body loses its main source of impartial, evidence based reporting on sanctions violations, creating an oversight vacuum that benefits only the Iranian regime and those who profit from evading these measures,” Loseta said after the vote.

What Response Is France Preparing?

France’s ambassador, Jerome Bonnefon, who holds the Security Council presidency this month, said Paris is considering setting up a separate monitoring team together with Germany, the United Kingdom and the United States, following the model used after Russia’s veto of the North Korea panel in 2024. That precedent shows that a Security Council veto no longer necessarily means the end of monitoring, only its relocation outside the UN’s formal structures, into a coalition of willing states, a solution that weakens the Council’s own legitimacy even as it technically keeps up pressure on Tehran.

Additional pressure on Iran is also coming from the International Atomic Energy Agency, which estimates that Iran holds 440.9 kilograms of uranium enriched to 60 percent purity, one step below weapons grade. The Agency’s Board of Governors adopted a resolution on September 10 demanding that Iran resolve its noncompliance with the Nuclear Non-Proliferation Treaty, the first such referral to the Security Council and General Assembly in the past two decades. The head of Iran’s Atomic Energy Organization, Mohammad Eslami, did not even make it to the Agency’s annual conference in Vienna because of it, after Austria revoked his visa once the Security Council had already refused to grant him an exemption from the sanctions regime’s travel ban.

Why This Matters for Belgrade

For Serbia, which builds its foreign policy on a parallel reliance on multilateral institutions and its European path, Thursday’s veto is a reminder that the Security Council is increasingly less a place where rules apply evenly and increasingly more an arena where a diplomatic channel between Washington, Moscow and Beijing decides what even reaches a vote. The same pattern, a permanent member’s veto shutting down a monitoring mechanism when it does not suit them, is directly relevant to Serbia’s own position on Kosovo, since Resolution 1244 depends on the same institution whose authority was weakened once again on Thursday. At the same time, the European Union runs its own sanctions regime against Iran independently of the UN mechanism, so every candidate country, Serbia included, that aligns its foreign policy with Brussels’ Common Foreign and Security Policy has to track both tracks in parallel.

The next chance for the issue to return to the agenda of the major powers comes as soon as next week in New York, at the UN General Assembly session, for which the US State Department has approved visas for Iran’s entire “core delegation,” including President Masoud Pezeshkian and foreign policy chief Abbas Araghchi.
