In an interview with Mizan on Monday, Behrouz Kamalvandi said the third step in reducing Iran’s commitments under the JCPOA “will be definitely taken”.
The beginning of the new step will be announced within the next few days, he noted.
On Sunday, Iranian Foreign Minister Mohammad Javad Zarif said Tehran will start the third phase of reducing its JCPOA commitments if Europe fails to fulfill its side of the bargain until September 5.
“Our negotiations with Europe are underway, but measures have also been taken on the third step of reducing JCPOA commitments, and we are in final stages of decision-making,” Zarif told reporters in Tehran.
Tehran has rowed back on its nuclear commitments twice in compliance with articles 26 and 36 of the 2015 deal.
As a first step Iran increased its enriched uranium stockpile to beyond the 300 kilograms set by the JCPOA.
In the second step, Tehran began enriching uranium to purity rates beyond the JCPOA-limit of 3.76 percent.
