Russian Foreign Minister Sergei Lavrov said in a statement, that he discussed positions on Iran with the U.S. Secretary of State Rex Tillerson during their first bilateral meeting.

“We discussed Iran, as well as other key issues of international agenda. The Joint Comprehensive Plan of Action, which has settled the problem of the Iranian nuclear program, will remain in place. The U.S. continues to take part in monitoring of the implementation of the document along with other participants,” Lavrov told reporters.

Iran, five permanent UN Security Council members, Germany, and the European Union signed the Joint Comprehensive Plan of Action in July 2015 to ensure that Iran’s nuclear program remains peaceful. Iran pledged to refrain from developing or acquiring nuclear weapons in exchange for the lifting of sanctions imposed against Iran.

The UN resolution was passed shortly afterwards, reaffirming the nuclear agreement. The U.S. President Donald Trump has repeatedly criticized the Iranian nuclear agreement during his election campaign and after winning the race.
