Russian Foreign Minister Sergei Lavrov and US Secretary of State Mike Pompeo spoke on the phone on Sunday about Russia's proposal to hold a video summit at the United Nations to discuss Iran, the Russian foreign ministry said.
Russian President Vladimir Putin proposed a video summit with the United States and the remaining parties to a 2015 nuclear deal between Iran and world powers - Britain, France, China, Germany and Iran - to try to avoid further "confrontation and escalation" over Iran at the United Nations.
The Security Council has decided not to renew a UN arms embargo on Iran.
The 15-member council on Friday resoundingly defeated a US resolution to indefinitely extend the embargo. Only the Dominican Republican joined the US in supporting the resolution. Russia and China opposed it, while the remaining 11 members abstained.
The Trump administration has said it will not allow the arms embargo provision in the Security Council resolution endorsing the 2015 nuclear agreement to expire as scheduled Oct. 18.
Pompeo has suggested the US would invoke the “snap back” mechanism in the deal that would restore all UN sanctions on Iran.
