Iranian President Masoud Pesekian arrived in Russia on Friday for an official visit and is expected to hold talks with Russian President Vladimir Putin.
The Iranian leader's plane landed at Moscow's Vnukovo Airport at around 10 a.m. local time, according to TASS.
"Pezeshkian is scheduled to hold talks with Russian President Vladimir Putin, after which the presidents will sign an agreement on a comprehensive strategic partnership between Moscow and Tehran," the agency said in a statement.
The two leaders will, as previously reported by the Kremlin, also discuss options for further expanding ties between Moscow and Tehran, including trade and investment, transport and logistics, and the humanitarian sphere.
Pezeshkian was met at the airport by a Russian delegation led by Energy Minister Sergei Civilev. He was accompanied by Deputy Foreign Minister Andrei Rudenko and Head of the State Protocol Department of the Ministry of Foreign Affairs Igor Bogdashev.
The Iranian president met with Putin twice - in October last year, first on the sidelines of an international forum in Ashgabat, Turkmenistan, and later at the BRICS summit in Kazan.
In August, Pezeshkian promised Russian Security Council Secretary Sergei Shoigu that he would take revenge on Israel for the assassination of Hamas Politburo leader Ismail Haniyeh.
Russia has been strengthening ties with Iran and other countries hostile to the United States, such as North Korea, since the start of the war in Ukraine.
Russian Foreign Minister Sergei Lavrov said in October that Moscow and Tehran intend to sign a strategic partnership pact that would include closer cooperation in the field of defense.
The United States in September accused Tehran of supplying ballistic missiles to Russia for use against Ukraine and imposed sanctions on ships and companies it said were involved in supplying Iranian weapons. Tehran denies giving Moscow the missiles.
