Russian President Vladimir Putin has told Iranian President Massoud Pezeshkian that Moscow wants a "fair" nuclear agreement between the US and Iran and is ready to help advance the talks, AFP reported.

"The Russian side confirmed its readiness to contribute to the promotion of this dialogue with the aim of reaching a fair agreement based on the principles of international law," the Kremlin said of the talks between the Russian president and Pezeshkian.

The latest round of talks between Tehran and Washington, originally scheduled for May 3, was postponed, with mediator Oman citing "logistical reasons" for the delay.

The two sides have held three rounds since April 12, their highest-level contact since the US withdrew from the landmark agreement with Iran in 2018, during Donald Trump's first term as president.

Russia has deepened its military and diplomatic ties with Iran since it launched its offensive in Ukraine in February 2022. 

The two countries, both under massive Western sanctions, signed a strategic partnership earlier this year. Most recently, Moscow sent two aircraft to help put out a fire after a deadly explosion at Iran's largest commercial port.

Earlier, Russia confirmed its readiness to help find a diplomatic solution to the standoff between Washington and Tehran and to play any role in the negotiations. | BGNES
