Josep Borrell, the chief of foreign affairs for the European Union, has received a response from Iran in the discussions for reviving the nuclear agreement with the Islamic Republic and has given copies of it to each of the other negotiators, according to a spokeswoman.

Everyone is currently examining this response, according to Borrell’s spokesman Peter Stano on Friday.

“The way ahead will be – as always – discussed with all participants and the U.S.,” he added, referring to the other signatories of the 2015 agreement – Britain, China, France, Germany, Russia – and the United States.

In 2018, then-U.S. President Donald Trump quit the agreement and reimposed harsh sanctions on Iran, prompting Tehran to violate undertakings it had made under the pact by rebuilding stockpiles of enriched uranium and installing advanced centrifuges to speed up output.

Borrell is coordinating the talks aimed at reviving the agreement.

In March, the nuclear deal appeared near revival.

But indirect talks between Tehran and Washington then broke down over several issues, including Tehran’s insistence that the International Atomic Energy Agency (IAEA) close its probes into uranium traces found at three undeclared sites before the nuclear pact is revived.
