Iran has sharply rejected a resolution passed by the International Atomic Energy Agency’s (IAEA) Board of Governors, accusing it of being "politically driven" and "biased". In a joint statement released Thursday by the Foreign Ministry and the Atomic Energy Organization of Iran (AEOI), Iranian officials condemned the resolution and unveiled a series of countermeasures aimed at accelerating the country’s nuclear program.

This comes shortly after the IAEA Board of Governors passed a resolution against Iran on Thursday, claiming Iran was in breach of non-proliferation obligations. The vote passed with 19 countries voting in favor, 3 opposing, and 11 abstaining, according to diplomats cited by Reuters. Two countries were absent and thus did not vote.

The resolution, marking the first formal accusation in nearly two decades that Iran has violated its nuclear non-proliferation obligations, was passed during a closed-door session of the 35-member board. The move, described as "politically motivated" by Iranian officials, was initiated by the United States along with the E3, Britain, France, and Germany.

IAEA resolution lacks 'neutrality'

The joint statement asserted that Iran remains committed to its obligations under the Safeguards Agreement, adding that no IAEA report to date has ever confirmed any deviation or non-compliance. Iranian authorities described the IAEA’s latest move as lacking “neutrality” and being manipulated by Western powers, particularly the United States, Britain, France, and Germany, to pursue geopolitical goals.

In a direct response, Iran announced the activation of a new uranium enrichment facility at a secure site and plans to upgrade the Fordow nuclear plant by replacing older centrifuges with sixth-generation advanced models.

Iran blasts Western double standards on nuclear disarmament

Iranian officials criticized the IAEA and its Western backers for what they described as selective enforcement of nuclear obligations. The joint statement accused the US and its European allies of reviving “25-year-old allegations” that had already been settled under the 2015 nuclear deal, while turning a blind eye to “Israel’s” undeclared nuclear arsenal and refusal to adhere to the Non-Proliferation Treaty (NPT).

“The United States, Britain, and France have failed to comply with Article VI of the NPT regarding nuclear disarmament,” the statement read, adding that Germany remains in possession of “inhumane weapons of mass destruction.”

Iran further warned that continued political maneuvering within the IAEA would render any future engagement futile. “This political approach toward Iran, which has always honored its obligations and cooperated extensively with the Agency, forces us to conclude that the path of engagement and cooperation is futile," the statement asserted.

Iran thanks allies opposing the resolution 

Iran’s Foreign Ministry spokesperson, Esmaeil Baghaei, strongly condemned the resolution passed Thursday by the IAEA Board of Governors, calling it a politically motivated effort by Western powers to undermine the peaceful nature of Iran’s nuclear program.

Baghaei specifically denounced the role of the United States, the United Kingdom, France, and Germany, accusing them of exploiting the IAEA to “cast doubt on the peaceful nature of Iran's nuclear program.”

He firmly rejected the allegations outlined in the resolution, which he said were based on “baseless and unfounded claims” and stemmed from a political report by the IAEA Director General. The resolution, jointly submitted by the four Western states, was described as “an unjustified, groundless, and cruel move,” aimed at exerting “maximum pressure on Iran to deviate from the legitimate rights and interests of the Iranian people in the peaceful use of nuclear energy.”

Baghaei warned that those behind the resolution will be held accountable for its repercussions. “The Islamic Republic of Iran will take proportionate measures in response to this move to secure and protect the interests and inalienable rights of the Iranian nation in benefiting from peaceful nuclear energy,” he said.

He also expressed deep concern over the conduct of the IAEA Director General, criticizing his public statements and what he described as provocative interviews on Iran’s nuclear activities. Baghaei accused the agency chief of undermining the organization’s neutrality, stating that he “must adhere to his missions and duties in accordance with the Agency's statute.”

Furthermore, the Iranian diplomat extended gratitude to China, Russia, Venezuela, Cuba, Nicaragua, and Belarus for issuing a joint statement rejecting the resolution. He praised their “responsible and legal positions” and reaffirmed the Iranian nation’s determination to defend its rights and interests as outlined in the United Nations Charter and the Non-Proliferation Treaty.

Iran’s IAEA representative Najafi slams politicized resolution 

Iran’s representative at the International Atomic Energy Agency (IAEA), Reza Najafi, strongly criticized the agency’s recent resolution against Iran, denouncing it as politically motivated and based on unreliable sources. Speaking on Thursday, Najafi warned that such moves undermine the IAEA’s credibility and threaten the rights of member states under its founding charter.

Najafi emphasized that any draft resolution brought forward by the Board of Governors should rely strictly on unbiased, verifiable evidence, not intelligence supplied by specific states with vested interests. “Basing reports on questionable or politicized information undermines the agency’s objectivity,” he stated, in clear reference to data provided by Western governments and the Israeli occupation.

US current approach risks setting a dangerous precedent

He warned that the United States’ current approach risks setting a dangerous precedent, one that could erode trust and cooperation between the agency and its member states. Najafi asserted that such behavior contradicts the IAEA’s stated commitment to impartiality and transparency.

Reaffirming Iran’s position, Najafi made it clear that the Islamic Republic would not tolerate any attempt to erode its sovereignty through international pressure.

"Iran categorically rejects any pressure or mediation that seeks to undermine its sovereignty. We will defend our national interests, independence, and dignity,” he declared.

Politicized resolution in disguise

Najafi also expressed Iran’s outright rejection of what he described as a politicized resolution disguised as a technical safeguard concern, echoing Tehran’s longstanding understanding that the IAEA is being used as a tool for Western geopolitical agendas.

In a pointed warning to the E3, Britain, France, and Germany, as well as the United States, Najafi made it clear that Iran’s response would be firm. “These measures will not pass without consequences. They must take full responsibility for the repercussions and Iran’s strong reaction,” he said.

Kamalvandi: Political pressure will escalate Iran’s nuclear program

Behrouz Kamalvandi, Deputy Head of the Atomic Energy Organization, reinforced the government’s defiant tone, declaring that political pressure would only accelerate Iran’s nuclear ambitions.

“It is a strategic mistake to think that political pressure will push Iran to abandon its legitimate positions,” Kamalvandi said, warning that the current approach would “backfire".

He confirmed that Iran would soon launch a third uranium enrichment facility, in addition to boosting enrichment capacity at existing sites. “We will develop sixth-generation centrifuges and increase uranium enrichment significantly,” he stated.

More Western pressure, more Iranian countermeasures

Iran’s latest response underscores its growing rejection of Western pressure and marks a new phase in the country’s nuclear trajectory, one increasingly independent of multilateral negotiations and oversight mechanisms perceived by Tehran as compromised.

This development comes just days ahead of the sixth round of indirect nuclear talks between Iran and the United States, set to take place this Sunday in Muscat, Oman. The announcement was confirmed by Omani Foreign Minister Badr Albusaidi, who wrote in a post on X: “I am pleased to confirm the 6th round of Iran-US talks will be held in Muscat this Sunday, the 15th.”

Tehran and Washington have held five rounds of talks since April to carve a new nuclear deal to replace the 2015 accord that Trump unilaterally withdrew from during his first term in 2018.
