"I am convinced that our meeting is going to contribute towards reinforcing friendly relations between Russian and Iranian armed forces," Shoigu said in a statement quoted by AFP.
The statement added that he and Dehghan talked about "the necessary measures for the progressive development" of that cooperation and that both powers are "ready to coordinate their approaches on a large number of global and regional issues."
"Our countries face the same challenges and threats in the Middle East region and it is only together that we will be able to fight them," he added.
Russia is selling advanced S-300 air defense missile system to Iran. Russia also plans to sell Iran Su-30 Flanker air superiority fighter-bomber jets.
Washington opposes this saying it would violate the UN arms embargo on Tehran which was imposed following the nuclear deal which states Iran is banned from buying such weapons for the next five years.
