Speaking to reporters, Velayati said the two sides' officials are now mulling current developments in the Middle East region.
Relations between Tehran and Moscow throughout history has been very unprecedented and grounds for expansion of all-out mutual, regional and defense cooperation have been developed, he said.
Coalition made between Iran, Russia, Iraq and Syria is now bearing fruits, he said.
Both Iran and Syria are determined to broaden cooperation to help resolve Syrian crisis, Velayati said.
Iran and Russia are opposed to intervention in Syrian affairs and believe that the issue should be resolved through dialogue and for the same reason they back talks on Syria, he said.
