ERBIL, Kurdistan Region of Iraq – The International Atomic Energy Agency (IAEA) on Thursday approved a resolution that condemns Iran for failing to comply with its nuclear restrictions, with Tehran slamming the decision as “political” and saying it will increase enrichment in response.

The IAEA resolution, proposed by France, Germany, and the United Kingdom, passed with 19 of 35 countries voting in favor of the measure.

China, Russia, and Burkina Faso voted against the resolution, with 11 other countries abstaining, according to AFP, citing diplomats with knowledge of the IAEA vote.

In response, the Atomic Energy Organization of Iran (AEOI) released a statement that said, “We condemn and deplore the political action of the countries that voted in favor,” noting that it now views cooperation with the watchdog as “counterproductive.”

The statement added that Iranian authorities would now open a new nuclear enrichment facility and enhance its capabilities at existing locations, saying Tehran “has no choice but to respond to this political resolution.”

“The necessary orders have been issued by the head of the [AEOI] to launch a new enrichment center in a secure location and to replace the first-generation machines at the Martyr Dr. Ali Mohammadi (Fordo) enrichment center with advanced sixth-generation machines,” the statement said, adding that “other measures are also being planned and will be announced later.”

Iran’s UN Ambassador Saeed Iravani wrote in a letter to the UN Security Council on Wednesday that Iran would consider “proportionate responses” were the UN to sanction Tehran over the alleged non-compliance, saying that “starting the process of withdrawal from the Non-Proliferation Treaty” would be on the cards.

The Iranian surge towards increased nuclear enrichment—long a salient sticking point in nuclear negotiations with the US—comes ahead of the next round of talks between Washington and Tehran on the issue that are scheduled for Sunday in the Omani capital of Muscat.
