Araghchi, speaking days after leading an economic delegation to France, ruled out any renegotiation of the JCPOA, but said Iran was open to talks on how to implement it better.

“Returning to full implementation of the JCPOA is subject to receiving $15 billion over a period of four months, otherwise the process of Iran reducing its commitments will continue,” he said.

But Araghchi cast doubt on the likelihood of an agreement being reached before the deadline set by Iran.

“I don’t think the European countries will be able to take an effective step before Friday… so we will take the third step,” he said.
