"I very much hope that there will be [a deal], though their partners are the Defense Ministry, the Federal Service for Military-Technical Cooperation, Rosoboronexport. This is not a matter the Foreign Ministry deals with," Kabulov told RIA Novosti.
He added that an Iranian delegation would visit Russia next week for talks on military-technical cooperation, to include the topic of S-300 deliveries.
"Yes, a large Iranian delegation will be arriving in Moscow. Firstly, they will participate in the MAKS air show, and, of course, a part of the delegation… will hold talks on military-technical cooperation," Kabulov said, adding that "the negotiations will of course include S-300s."
Russia and Iran initially signed an S-300 delivery deal in 2007. Its implementation was halted by Moscow after the UN Security Council issued an arms embargo on Tehran over concerns that it was developing nuclear weapons.
Russian President Vladimir Putin lifted the ban on S-300 deliveries in April, shortly after the P5+1 group of international negotiators and Iran reached a framework nuclear agreement, based on Tehran's pledge to reduce its uranium stockpiles and cut its number of centrifuges in exchange for sanctions relief.
