“Purchasing the S-300 air defense system is out of the jurisdiction of the Security Council's recent resolution,” Iranian media reports Araqchi as saying.
He said that there are seven weapons whose sale in Iran is restricted by the UN but the S-300 is not included in them.
Araqchi further mentioned that the European Union Foreign Policy Chief Federica Mogherini and French Foreign Minister Laurent Fabius are set to visit Iran next week.
Earlier it was reported that the recent comprehensive nuclear agreement between the six world powers and Iran could allow Tehran to gain access to more advanced air defense systems than the Russian S-300.
"The agreement on the nuclear program could lead to Iran being able to receive more advanced systems than S-300," a source in the Iranian Defense Ministry told Sputnik on Tuesday.
The source added that the precise schedule for the delivery of S-300 to Iran under the existing contract had not been yet determined.
In mid-June, a source familiar with the situation said that Russia and Iran were in talks on resuming the implementation of the S-300 delivery contract, signed in 2007 and worth about $800.
According to the source, Russian officials insisted on the withdrawal of the lawsuit and signing of a new contract instead.
