CEO of Russia’s state gas company has traveled to Tehran to meet Iran’s top security official some three months after the two countries signed a landmark gas supply agreement.

According to The Iran Project, Gazprom CEO Alexey Miller met with Ali Akbar Ahmadian, who serves as the Secretary of Iran’s Supreme National Security Council (SNSC), on Tuesday, according to a report by the official IRNA news agency.

It said Miller had traveled to Tehran to follow up on negotiations earlier this month in St. Petersburg between Ahmadian and Russian President Vladimir Putin.

Miller also briefed Ahmadian on agreements he had reached with senior Iranian energy sector officials, it said.

Ahmadian said in the meeting that leaders of Iran and Russia seek closer energy ties and that the SNSC will work toward the full implementation of contracts between the two countries.

Miller is the third senior Russian government official to visit Tehran after Ahmadian’s visit to Russia in early September to attend a meeting of top security officials of the BRICS grouping of developing countries.

Putin’s aide Igor Levitin and Russia’s Security Council Secretary Sergei Shoigu were in Tehran last week to meet with Ahmadian and other senior Iranian government officials.

Gazprom chief’s visit to Tehran also comes some three months after he came to Tehran to supervise the signing of major gas supply deal between the company and its Iranian counterpart the National Iranian Gas Company (NIGC).

Local media reports at the time suggested that Gazprom would supply some 300 million cubic meters per day of gas to Iran under the deal to enable the country to increase its exports via pipelines to Iraq and Turkey.

Russia has been facing an oversupply of natural gas since early 2022 when its exports to Europe came under sanctions because of the war in Ukraine.

Experts say the agreement between the NIGC and Gazprom could turn Iran into a major gas transfer hub in the region once it is fully implemented.
