WASHINGTON • The Biden administration said Thursday it’s ready to join talks with Iran and world powers to discuss a return to the 2015 nuclear deal. It’s also reversed the Trump administration’s determination that U.N. sanctions against Iran had been restored and eased stringent restrictions on the domestic U.S. travel of Iranian diplomats posted to the United Nations.

The State Department said the U.S. would accept an invitation from the European Union to attend a meeting of the participants in the original agreement. The U.S. has not participated in a meeting of those participants since former President Donald Trump withdrew from the deal in 2018.

“The United States would accept an invitation from the European Union High Representative to attend a meeting of the P5+1 and Iran to discuss a diplomatic way forward on Iran’s nuclear program,” State Department spokesman Ned Price said in a statement.

Such an invitation has not yet been issued but one is expected shortly after discussions Thursday between Secretary of State Antony Blinken and his British, French and German counterparts.

Meanwhile, at the United Nations, the administration notified the Security Council that it had withdrawn Trump’s September 2020 invocation of the “snapback” mechanism under which it maintained that all U.N. sanctions against Iran had been re-imposed. That determination had been vigorously disputed by nearly all other U.N. members and had left the U.S. isolated at the world body.

In another move, officials said the administration has eased extremely strict limits on the travel of Iranian diplomats accredited to the United Nations. The Trump administration had imposed the severe restrictions, which essentially confined them to their U.N. mission and the U.N. headquarters building in New York.

Earlier Thursday, Blinken and the foreign ministers of Britain, Germany and France urged Iran to allow continued United Nations nuclear inspections and stop nuclear activities that have no credible civilian use. They warned that Iran’s actions could threaten delicate efforts to bring the U.S. back into the 2015 deal and end sanctions damaging Iran’s economy.

Iran is “playing with fire,” said German Foreign Minister Heiko Maas, who took part in the talks Thursday in Paris with his British and French counterparts. Blinken had joined via videoconference.

Iran has said it will stop part of International Atomic Energy Agency inspections of its nuclear facilities next week if the West doesn’t implement its own commitments under the 2015 deal. The accord has been unraveling since Trump pulled the U.S. out of the agreement.

Blinken reiterated that “if Iran comes back into strict compliance with its commitments … the United States will do the same,” according to a joint statement after Thursday’s meeting that reflected closer trans-Atlantic positions on Iran since President Joe Biden took office.

The diplomats noted “the dangerous nature of a decision to limit IAEA access, and urge Iran to consider the consequences of such grave action, particularly at this time of renewed diplomatic opportunity.”

They said Iran’s decision to produce uranium enriched up to 20% and uranium metal has “no credible” civilian use.

The 2015 accord is aimed at preventing Iran from developing nuclear weapons. Tehran denies it is seeking such an arsenal.
