A large number of Russian companies are taking action to boost cooperation with Iran as several large delegations from European states are due to arrive in Iran in coming weeks to win a major share of the country's market after the recent agreement in Vienna.
Several Russian energy companies, including Lukoil energy firm, have voiced their readiness to return to Iran's market, the Business Insider reported.
Head of Lukoil Giant Oil Company Vagit Alekperov said that his company was eager to return to Iran as soon as the western sanctions will be lifted.
"Iran will have to develop the sectors that struggled under the sanctions," said Andrei Baklitsky, director of the nuclear non-proliferation program at Russia's Centre for Policy Studies.
"It will need foreign companies to come and invest; Russian companies, such as Russian Railways and Lukoil, are looking to take part in this."
Russian Foreign Minister Sergei Lavrov in the negotiations had called for the immediate lifting of an arms embargo against Iran.
In April, Russia lifted a self-imposed ban on selling the S-300 air defense systems to Iran. A Kremlin aide said last month that Russia and Iran were preparing a contract for deliveries of the air defense systems and there has been no official comment on how the deal will affect these plans.
"There will be fierce competition for Iran's energy industry, and later in the arms industry," Seregichev said.
"I think Russia will mostly strike at the energy sector because of its vast international experience in the field," he added.
On Wednesday, Russia's Transport Minister Maxim Sokolov announced that his country is in talks with Tehran on supplying Sukhoi super jet passenger planes to the country.
“Talks are underway on sale of super passenger jets between the two countries," Sokolov told reporters.
He declined to comment further on the details of the talks.
The Sukhoi super jet is the first new airliner Russia has developed since the fall of the Soviet Union in early 1990s.
Iran and the six world powers struck a deal in Vienna on July 14.
The hitherto elusive agreement was finally nailed down on Tuesday in the ritzy Palais Coburg Hotel in the Austrian capital of Vienna, where negotiators from Iran and the six other countries had recently been spending over two weeks to work out the remaining technical and political issues.
The agreement, the Joint Comprehensive Plan of Action (JCPOA), will be presented to the United Nations Security Council (UNSC) on Monday to adopt a resolution in the following two days to make the JCPOA an official document.
