"We have not come to a decision whether or not to remain in the Joint Comprehensive Plan of Action (JCPOA) yet," Araqchi said, as quoted by the Tasnim news agency.
He noted that Iran's further participation in the agreement depends on how the other signatories decide to compensate the exit of the United States.

"The European countries should tell us how they would be able to secure Iran’s interests in the JCPOA in the absence of the United States and with the return of the country’s sanctions," the deputy foreign minister said.
On May 8, US President Donald Trump announced the US withdrawal from the Iranian nuclear deal and outlined plans to re-impose sanctions on Iran, which had been lifted as part of the accord. The agreement was signed in 2015 by Iran, the European Union and the P5+1 group of countries — China, Germany, France, Russia, the United Kingdom and the United States.
The other JCPOA participants have criticized Trump’s decision to unilaterally pull out of the deal.
