Tehran and Moscow said Wednesday that they want to expand their cooperation in energy and trade Officials said on Wednesday, as Russian Deputy Prime Minister Alexander Novak visited Iran.

Both countries have massive oil and gas reserves but are hampered by Western sanctions that limit their ability to export their resources.

Novak led an economic delegation to Tehran in the midst of Russia’s invasion of Ukraine, which has sent global oil and gas prices skyrocketing.

“Iran and Russia are both under oppressive sanctions, which, God willing, can be neutralised by working together and developing relations in various fields,” Iran’s Oil Minister Javad Owji said, according to the ministry’s official news agency, Shana.

Russia’s Interfax news agency meanwhile quoted Novak as saying: “Energy is one of the most important sectors of our trade and economic cooperation.”

He added that they had discussed the potential for oil and gas swaps, as well as “increasing joint investments in oil and gas projects”.

Novak and Owji head the Iran-Russia Joint Commission on Trade and Economic Cooperation.

“Good agreements were reached in the fields of rail, road transport, shipping and aviation,” Owji said, without expanding further.

He added that both sides have “good capacities for cooperation in energy, banking, transportation, agriculture, nuclear energy, industry and trade”.

“We plan to increase the level of Iran-Russia trade relations in these fields to $40 billion a year,” the oil minister continued.

Russia was slapped with sanctions following its invasion of neighboring Ukraine, while Iran’s economy has been reeling under biting sanctions reimposed by the US in 2018, following its withdrawal from a 2015 nuclear accord between Tehran and world powers.

The two countries vowed to increase the use of their national currencies in their trade exchange.

“We agreed to switch over to the use of national currencies as much as possible,” Novak said.

Tehran and Moscow have close political, economic, and military ties.

Iran’s President Ebrahim Raisi visited Moscow in January and said he presented draught documents on strategic cooperation to his counterpart Vladimir Putin that would cement joint collaboration for the next two decades.
