Russia's TASS news agency quoted Vladimir Kozhin, an aide to President Vladimir Putin, as saying on Thursday that 'the contract is being implemented, (deliveries of S-300s) are starting.' The official did not disclose further details.
According to Press TV, last month, Sergei Chemezov, the chief executive of the Russian state-owned defense conglomerate, Rostec, said the deal for the S-300 delivery was already signed.
Russia committed to delivering the systems to Iran under a USD-800-million deal in 2007.
Moscow, however, refused to deliver the systems to Tehran in 2010 under the pretext that the agreement was covered by the fourth round of the United Nations Security Council sanctions against Iran over its nuclear program. The resolution bars hi-tech weapons sales to Tehran.
Following Moscow’s refusal to deliver the systems, Iran filed a complaint against the relevant Russian arms firm with the International Court of Arbitration in Geneva.
In April this year, President Putin lifted a previous ban on the delivery of S-300 to Iran.
