TEHRAN (FNA)- Iranian Ambassador to Moscow Mahmoud Reza Sajjadi on Monday said he is confident that Russia would soon deliver the sophisticated anti-aircraft S-300 missile system to Iran as Moscow's international creditability would be harmed otherwise.

""Given the fact that Russia's international creditability is pawned for a resolution of (existing) problems and fulfillment of the country's undertakings in this regard (delivery of S-300), I am confident that the job will be done at the earliest,"" Sajjadi told FNA.
Earlier at a press conference at the main office of RIA Novosti in Moscow on Thursday, Sajjadi had said that ""Iran is ready to receive this system and our Russian colleagues have assured us that they will meet their obligations"".
The head of Russia's state-run arms exporter Rosoboronexpor, Anatoly Isaikin, had also earlier stressed his country's commitment to continue military cooperation with Iran.
""Nothing prevents the continuation of military cooperation in those directions of interest to Russia and Iran,"" Isaikin added.
""Iran has never violated a single commitment it has undertaken with regard to military contracts,"" he reiterated.
Isaikin also stressed that Russia would not back down on the deal to sell the sophisticated S-300 anti-aircraft missile system to Iran.
Tehran has been seeking to purchase the sophisticated defense system to improve its deterrence power in reaction to Israeli war rhetoric against Iran's nuclear facilities.
Moscow signed a contract with Tehran in 2007 to supply the powerful S-300 missiles to Iran.
The S-300 surface-to-air system, known as the SA-20 in the West, can track targets and fire at aircraft 120 kilometers (75 miles) away. It also features high jamming immunity and is capable of simultaneously engaging up to 100 targets.
