In the meeting held in Tehran on Saturday, Jaberi Ansari and Naumkin exchanged views about a range of issues, including regional developments and Iran-Russia relations in diverse fields.
The two sides also discussed ways to help end the ongoing crises in Syria and Yemen.
Iran and Russia have formed a strong alliance in recent years, with both supporting the Syrian President Bashar al-Assad’s government against foreign-backed militancy.
They have also ramped up efforts to expand their ties in various political, economic, trade, scientific and academic spheres, especially since coming into force in January 2016 of the Joint Comprehensive Plan of Action (JCPOA), a nuclear deal between Iran and the Group 5+1 (Russia, China, the US, Britain, France and Germany).
