Iran on Sunday ruled out holding an informal meeting with the United States and other major powers to discuss ways to salvage the unravelling 2015 nuclear deal, insisting Washington must first lift all its unilateral sanctions.
"Considering the recent actions and statements by the United States and three European powers, Iran does not consider this the time to hold an informal meeting with these countries, which was proposed by the EU foreign policy chief," Foreign Ministry spokesman Saeed Khatibzadeh said, according to Iranian media.
The United States said it was disappointed but remained ready to "re-engage in meaningful diplomacy" and would consult with the other major powers to seek a way forward.
Iranian officials had said Tehran was studying a proposal by European Union foreign policy chief Josep Borrell to hold an informal meeting with other parties to the nuclear pact and the United States, which reimposed sanctions on Iran after then-President Donald Trump quit the deal in 2018.
The new administration of President Joe Biden has said it is ready to talk to Iran about both nations resuming compliance with the accord, which scrapped broad economic sanctions against Iran in return for curbs intended to prevent it from acquiring nuclear weapons - something Iran says it does not want.
But the parties cannot agree who should make the first move.
Iran says the United States must lift sanctions, while Washington says Tehran must return to compliance with the deal, which Iran has been progressively breaching since 2019.
A White House spokeswoman said Washington remained keen to achieve a "mutual return to compliance" with the deal.
She said it would consult with the major powers that are also parties to the deal - Britain, China, France, Germany and Russia - on the best way forward.
