Russia and China Veto UN Panel That Would Have Kept Tracking Iran Sanctions Violations

Since the Security Council's snapback mechanism reimposed sanctions on Iran on September 27, 2025, enforcement has depended on a panel of independent experts to document violations. That panel is now dead. Russia and China vetoed a US-drafted resolution on Thursday, September 17, that would have extended the panel's mandate another year, according to Al Jazeera, the Associated Press (via Courthouse News Service), and The Independent.

The vote was 11 in favor, with Pakistan and Somalia abstaining, and Russia and China casting the two dissenting votes needed to trigger a veto, according to Anadolu Agency and The National. The panel's mandate expires September 26.

Russian UN Ambassador Vassily Nebenzia told the council the underlying legal basis was invalid, arguing that Resolution 2231, the document that anchored the 2015 nuclear deal, expired on October 18, 2025, meaning there was "no procedural or legal foundation" for the meeting at all, per Anadolu. France, which held the council presidency this session, countered that Resolution 1929 was legally restored through the snapback provision acknowledged by the UN Secretary-General, obligating the council to renew the monitoring body, Anadolu reported.

Russia and China's position is that the sanctions snapback triggered by France, Germany and the UK lapsed on its own terms before it could be permanently reinstated. Whether that argument is legally sound remains contested at the Security Council itself. No international court has ruled on it.

US Deputy Ambassador Jennifer Locetta said the outcome wasn't a surprise. She told the council the experts "would have shined the light" on prohibited defense cooperation between Iran and its partners, and argued the veto fits a broader pattern of Moscow and Beijing blocking or delaying expert panels, citing North Korea in March 2024, Mali, Yemen and the Central African Republic, according to the AP report carried by Courthouse News and The Independent.

Britain went further, accusing Russia and China of choosing "to shield Iran" while Tehran "accelerates nuclear enrichment without credible civilian justification" and continues barring inspectors, per Anadolu.

Iran's UN mission thanked Moscow and Beijing on social media, saying they "prevented yet another cynical attempt by the United States and its allies to abuse the Security Council for their political purposes," according to Al Jazeera and The Independent.

The IAEA Referral Still Stands

The veto follows a separate escalation days earlier. On September 9, the IAEA Board of Governors voted 23-3-8 to refer Iran to the Security Council for breaching its nuclear safeguards obligations, the first such referral in two decades, according to the Epoch Times. IAEA Director General Rafael Grossi has said inspectors have been unable to verify Iran's enriched uranium stockpile, last reported at 440.9 kilograms enriched to 60% purity, since the June 2025 US-Israeli strikes on Iranian nuclear sites, per the AP.

Iran's ambassador to the IAEA, Reza Najafi, rejected the referral as a "half-truth," arguing Tehran hasn't suspended its safeguards obligations but is "simply unable to perform them" because US and Israeli strikes destroyed the access conditions inspectors need, the Epoch Times reported. The dispute over whether Tehran is actually complying remains unresolved.

Sanctions Enforcement and Satellite Evidence Move on a Separate Track

Separately Thursday, the Treasury and State Departments announced sanctions on two companies, BitBank and Pishtaz Simorgh Electronic Trade Co., along with three associates of BitBank's previously sanctioned chief, Babak Zanjani, accusing them of helping Iran evade sanctions through digital currency networks, according to the AP.

Meanwhile, the Institute for Science and International Security reported Thursday that satellite imagery from September 11 shows Iran has added soil over tunnel entrances at Pickaxe Mountain, near the Natanz complex, further hardening the site against aerial attack, Fox News reported. Earthen roadblocks remain on access roads, which the institute says reinforces its assessment that the facility isn't in normal operation but likely still holds sensitive equipment or materials.

The imagery follows President Trump's warning last week that Iran shouldn't "get cute" at the site, saying the US would "hit them very hard" if provoked, per Fox News. Trump has floated striking Pickaxe Mountain directly since at least July.

With the expert panel now defunct and the sanctions committee paralyzed for over nine months by disagreement on subsidiary chairs, per The National, the US said it will bypass panel efforts entirely and instead focus on appointing a sanctions committee chair and updating its own designations, according to Anadolu. Inspectors have been unable to verify Iran's uranium stockpile since the June 2025 strikes, according to the AP — a gap of several months that the Security Council left unresolved Thursday.
