Citing UN sanctions, Russia has cancelled a planned sale of advanced missiles to Iran. Dmitry Medvedev, the Russian president, has issued a decree prohibiting the delivery of S-300 air defence missile systems and other weapons to Iran.
Reuters news agency reports that the presidential decree, issued on Wednesday, brings trade rules for Russia and its companies into line with the sanctions, pleasing the United States and other Western nations that are deeply worried about Iran's military capability.
"What's interesting about this order is that it not only bans the sale of surface-to-air S-300 missiles, it also bans other weapons system," Alexander Nekrassov, former adviser to the Kremlin, told Al Jazeera.
He added that the decree also bans senior Iranian officials "who are somehow linked to the nuclear programme" from visiting Russia.
