Russian leader Vladimir Putin and Iranian President Hassan Rouhani made a joint statement after their meeting in the Kremlin on March 28, according to TASS.
He added that Tehran-Moscow ties would never be against the interests of any third country. "For Russia, Iran is one of their most important political allies", said Mohsen Milani, executive director of the Center for Strategic and Diplomatic Studies at the University of South Florida. The news of his visit was announced by the Kremlin last week.
Putin said the two countries "cooperate within the framework of Gas Exporting Countries Forum and coordinate efforts in stabilising the world oil markets".

"Suffice it to say that previous year our trade grew 70 percent, which is a unique achievement amid the current economic difficulties", he added.
Iran and Russian Federation are expected to sign more than a dozen bilateral agreements during Rouhani's visit.

Among those warranting deepened scrutiny are applicants who have ever been "present in an ISIS-controlled territory". Tillerson's cable also restricts the number of interviews one visa officer can do every day.
In recent years, bilateral relations have developed in a positive way, stated the Rohani, who expressed hope of further agreements on new steps to strengthen them.
The two presidents have also held several phone conversations and discussed the available avenues for the continuation of bilateral cooperation on the crisis in Syria and the fight against global terrorism.
"This is a working document, not the first between Rosatom and the Atomic Energy Organization of Iran", the source said.
Putin also hailed the countries' role in ensuring peace in Syria, where both Russian Federation and Iran have shored up Assad. Russian Federation does not have a military base in Iran and the availability of Iranian military infrastructure is expected to boost its effectiveness in Syria.
Russian Federation and Iran have pledged to continue efforts to rein in oil production and stabilize markets, the presidents of both countries said in a joint statement on Tuesday.
Rouhani said that Moscow and Tehran had "begun effective cooperation" in countering "terrorists" in Syria, in a speech at Moscow State University where he was granted an honorary doctorate.
