"We are strictly adhering to all international commitments we have undertaken. We have documents adopted by the United Nations and all subsequent decrees of the country (Russia's) leadership. This concerns both Libya and Iran," Shugaev said, Sputnik news reported on Monday.
He added that Iran and Russia are now in talks over the maintenance of the Russian-made S-300 air defense missile system.
Iran took delivery of missiles of the S-300 system in July 2016.
In March 2017, during a war game dubbed Damavand, the country’s Air Defense conducted a successful test of the S-300 anti-aircraft missile system.
The system can detect 20 targets simultaneously and directly engage with 12 separate hostile flying objects, including missiles, fighter jets or helicopters.
