Russia's Vladimir Putin held talks with Iranian President Masoud Pezeshkian on Friday in Turkmenistan, where the two leaders hailed their countries growing economic ties and similar views on world affairs, an entente viewed with concern by the United States.
At odds with Washington and the European Union over Russia's war in Ukraine, something he casts as part of a wider existential struggle against an arrogant and self-interested West - Putin is keen to deepen ties with what he calls the Global East and Global South.
Putin, whose country is hosting a summit of the BRICS nations in Kazan on 22-24 October, invited Pezeshkian to come to Russia on an official visit, a proposal the Iranian leader accepted according to Russia's state RIA news agency.
"Economically and culturally, our communications are being strengthened day by day and becoming more robust," Pezeshkian was cited as telling Putin by Iran's official IRNA news agency.
"The growing trend of cooperation between Iran and Russia, considering the will of the top leaders of both countries, must be accelerated to strengthen these ties," he said.
In a later report from Dubai, Russia's TASS news agency quoted the Iranian president, in a video issued by his office, as saying the two sides had agreed to boost cooperation in a number of areas.
"Our talks with the Russian president lasted about an hour. And we talked again about agreements that we have concluded," the report quoted him as saying.
"We have constructive interaction. We agreed to speed up the completion of projects in the gas sectors, in road and rail construction, desalination and other projects linked to energy, petrochemicals and electricity."
Pezeshkian last month committed his country to deeper ties with Russia to counter Western sanctions. The two countries say they are close to signing a strategic partnership agreement, something Pezeshkian said on Friday he hoped could be finalised at the BRICS summit in Russia later this month.
The United States regards Moscow's growing relationship with Tehran with concern. It has accused Iran of supplying Russia with ballistic missiles for use in the conflict in Ukraine, something Tehran has denied.
