The resolution, introduced by the United States, Britain, France, and Germany, was approved on Wednesday with 21 votes in favor, 10 abstentions, and 3 votes against. It calls on Iran to inform the IAEA about the fate of bombed nuclear facilities and the enriched uranium they contained.

In a message posted on its X account shortly after the vote, the Iranian mission questioned the legitimacy of the vote and the integrity of the IAEA itself, vowing that Tehran will defend its rights in response to “this flawed resolution.”

“Today, the Board of Governors adopted, with a shaky vote, another political resolution on Iran’s peaceful nuclear activities, devoid of the professionalism expected from a technical body,” the mission said in a statement.

How can IAEA be trusted?

It censured the IAEA’s inaction over repeated military strikes on Iranian nuclear sites.

“How can the IAEA be trusted when instrumentalized by warmongers and decapitated in a way that is not even able to express a simple concern over the most extensive unlawful armed attacks — unprecedented in its history — on peaceful safeguarded nuclear facilities of a member state?” the post read, referring to US and Israeli attacks on IAEA‑monitored installations in Iran.

Mission further accused the resolution's backers of hypocrisy.

“A diplomatic solution needs a minimum good faith,” the message stated. It noted that the United States continues its acts of aggression, including against Iran’s civilian infrastructure, even as the resolution purported to support diplomacy.

The resolution’s approval came despite Iran’s warning against West's misuse of the Board of Governors to legitimize its illegal actions.

Foreign Minister Abbas Araghchi had urged member states before the vote to approach the issue with “vigilance, impartiality, and responsibility” and not to allow the IAEA to once again become “a political tool of the United States.”

Araghchi reminded the board that the main sponsor of the draft was “the very source of the crisis.”

Joint statement by Iran, Russia, China

Earlier on Wednesday, Iran, Russia, and China issued a joint statement urging all members to carefully consider the implications of the draft resolution and refrain from supporting “the politically‑motivated, untimely and unconstructive” move.

The statement warned that the US‑E3 action risks further weakening cooperation between the IAEA and Tehran, as well as jeopardizing ongoing diplomatic efforts to bring peace to the region.
