Mikhail Ulyanov made the remarks in an interview with the Russian newspaper Izvestia, published on Friday, according to Mehr news agency.
He reminded everyone that negotiations on the restoration of the Iranian nuclear deal were held in Vienna from April 2021 to March 2022.
“A detailed decision was then prepared, which provided for the phased lifting of all US sanctions against Iran and the simultaneous return of Tehran to those parameters of its nuclear program that were included in the JCPOA,” he said.
However, he added, “the favorable and appropriate moment” was lost, and absolutely nothing has happened in the last year and a half.
The Russian diplomat noted that the problem lies mainly in the position of Berlin, London, and Paris, as well as Washington, which unilaterally withdrew from the deal back in 2018.
“In my opinion, they are making a strategic mistake, because the issue is in limbo, and tensions can escalate at any moment, bearing extremely unpleasant consequences,” Ulyanov warned.
