Earlier on Wednesday, Lavrov held talks with his Iranian counterpart, Hossein Amirabdollahian, in Moscow. The two ministers discussed a range of issues including Ukraine, Afghanistan and bilateral cooperation.
"Now Mr. Minister [Amirabdollahian] mentioned in his opening remarks that some European leaders are asking him to focus on the Ukrainian issue, asking him to deliver some kind of a message. I hope that this is not a new precondition that some European leaders may put forward and put in the way of concluding the JCPOA," Lavrov said at a joint press conference.
The JCPOA deal was sealed in 2015 by China, France, Germany, Iran, Russia, the United Kingdom and the United States, as well as the European Union. Former US President Donald Trump unilaterally withdrew from the deal in 2018 and reimposed sanctions on Tehran.
Talks between Iran and the global powers to revive the deal and end US sanctions on Iranian oil exports have gained momentum recently. EU foreign policy chief Josep Borrel said on Wednesday that an agreement to revive the 2015 nuclear deal will hopefully be reached in the next few days.
