Russian Foreign Minister Sergei Lavrov and U.S. Secretary of State Mike Pompeo spoke on the phone on Sunday about Russia's proposal to hold a video summit to discuss Iran, the Russian Foreign Ministry said.

On Friday, Russian President Vladimir Putin proposed a meeting of the United Nations Security Council's permanent members and Germany and Iran to discuss problems with the implementation of the Joint Comprehensive Plan of Action, also better known as the Iran nuclear deal.

"We suggest holding an online meeting of the heads of state from the five permanent members of the UN Security Council and the leaders of Germany and Iran in the near future," Putin said in a statement. 

During the phone call with Pompeo, Lavrov reaffirmed Russia's full support for UN Security Council Resolution 2231, which created the international legal basis for the implementation of the Iran nuclear deal, the Russian Foreign Ministry said in a press release.

Lavrov said the Iran nuclear deal is a major political and diplomatic achievement aimed at strengthening the nuclear non-proliferation regime and regional security in the Middle East, the release said. 

According to the release, Lavrov and Pompeo also discussed scheduling bilateral contact in the near future. 

Before the talks, the United States lost a bid to extend a UN arms embargo on Iran on Friday.

"The Security Council's failure to act decisively in defense of international peace and security is inexcusable," Pompeo said in a statement. "The Security Council rejected direct appeals to extend the arms embargo from numerous countries in the Middle East endangered by Iran's violence."

China welcomes Russia's proposal and appreciates the efforts that Russia has made in de-escalating the tensions over the Iran nuclear deal.

Commenting on the video summit, Chinese Foreign Ministry spokesperson Zhao Lijian said that China is willing to keep in close contact with related parties to advance the political settlement process of resolving Iran's nuclear issues.
