In a recent interview with the Russian Kommersant, the director general of Russia’s Rosoboronexport, Anatoly Isaykin, said Russia and Iran were seeking a solution to the termination of an agreement, signed in 2007, for the delivery of Russian-built S-300 surface-to-air missile systems to Iran. Russia terminated the agreement in 2010 because of UN Security Council sanctions on Iran. In response to this, Iran commenced international arbitration proceedings in Geneva.

Isaykin told Kommersant: “This is the legitimate right of the Iranian side to bring a suit in international arbitration for the failure to perform a contract…But I am sure we will reach a compromise solution.”
