MOSCOW, December 7. /TASS/. Russia hopes for a considerable expansion of the military-technical cooperation with Iran after all restrictions on supplies to that country are lifted, the Russian presidential aide on military-technical cooperation told the Izvestiya daily.

"When all restrictions and all sanctions are lifted, I think we will have a rather serious development in the sphere of military-technical cooperation, it partially now embraces items not covered by sanctions, and we hope for very large projects in the future," Vladimir Kozhin said.

"The interest of the Iranian side is huge. They really need serious upgrade of their entire armed forces… Taking into account that it is a large country with large armed forces, of course, the talk will be about very large contracts, worth billions," Kozhin said.

Earlier he said Russia is starting delivery to Iran of S-300 air defense missile systems as part of the contract whose implementation was delayed by UN Security Council sanctions.

In early November, a new contract on supply of the systems to Iran entered into force. It was struck after in spring Russian President Vladimir Putin lifted a ban on the sale to Tehran of those air defense missile systems. It was reported that Iran will obtain the systems in the S-300PMU-2 variant.

Kozhin also reported that Iran is interested in the delivery of all types of Russian armaments, not only S-300 systems.
