Tehran, Sept 11, IRNA � The Islamic Republic delegation while in New York to participate in the upcoming UN General Assembly's annual session will pursue the case of the US disloyalty to Iran's nuclear deal, says Ali-Akbar Velayati.


The head of the Center for Strategic Research of the Expediency Council told reporters on Sunday that the United States has failed to remain committed to its promises and Washington has shown disloyalty.

'We distinguish between P5+1 member countries,' he said.

'Undoubtedly, the behavior of the Russia and the China was different from that exhibited by other member states and maybe we can regard France different from others as well,' Velayati said.

Washington opposed to Russia's decision to sell S-300 missile system to Iran arguing that it was in contradiction to the nuclear deal, but the Russians firmly responded them and said that the delivery of the system was not against the deal.

'We do not consider the P5+1 member states as being the same. Their behavior is different from each other and it is the United States tending to break its promises more than others.'
