Following Tehran’s announcement that it would resume nuclear discussions with Western powers at the end of November, France warned on Thursday that it might still act with its partners against Iran at a forthcoming meeting of the UN nuclear watchdog’s board.

After Tehran agreed to extend monitoring of some nuclear activity and invited IAEA Director General Rafael Grossi to Tehran for talks on important outstanding problems, Western countries scrapped preparations for a resolution denouncing Iran at the International Atomic Energy Agency in September.

The decision by the United States, France, Britain and Germany not to push for a resolution by the IAEA’s 35-nation board of governors avoided an escalation with Iran that could have killed hopes of resuming wider talks in Vienna on reviving the 2015 nuclear deal.

Iran and the European Union, which coordinates those negotiations, said on Wednesday that all sides had agreed to return to the Austrian capital on Nov. 29.

When asked whether Iran’s decision to return to the nuclear talks would make it unlikely that Western powers rebuke Tehran when the IAEA board holds it next quarterly meeting from Nov. 18, Legendre said Paris remained extremely concerned about Iran’s breaches of its obligations and commitments, including those made in September.

“Together with our partners, we remain very attentive to ensuring that Iran respects its commitments, and we remain in close consultation on the response to be provided on this,” she said.
