In an interview with IRNA which was published on Sunday, Jalali said that the landmark project would benefit both sides.
In the past, there were some speculations that Tehran and Moscow were rivals when it came to energy, the diplomat said.
Jalali went on to say that, however, when policies are adopted based on mutual interests, they will turn into lasting policies.
The Iranian envoy also called the Iran-Russia gas deal a mega-project.
Russia ranked first from March 21, 2023, to March 19, 2024, in terms of making investments in Iran, Jalali underlined.
To finalize the deal on gas transfer, the two countries held intense talks, he added.
On June 26, an MoU on Russian gas transfer to Iran was signed during a ceremony attended by the high-ranking officials of the two countries.
“A strategic memorandum has been signed with the National Iranian Gas Company (NIGC)”, a statement by Gazprom said, adding “the parties proceed from developing long-term mutually beneficial cooperation going forward”.
Iran’s Minister of Petroleum Javad Owji said the signing of the memorandum will yield favorable changes in the energy balance in the region, where Iran will be fully ready to receive gas from Russia with its infrastructure and gas transmission lines.
The gas agreement, he added, will bring about a revolution in the energy and industrial ecosystem of the region.
