Despite areas of difference and rivalries between Moscow and Tehran, ties between the two countries based on common interests have developed significantly.
Both Russia and Iran are both major energy exporters, they have deeply seated interests in the South Caucasus. They are both firmly opposed to NATO’s missile shield, with a view to preventing the U.S. and E.U. from controlling the energy corridors around the Caspian Sea Basin.
Moscow and Tehran’s bilateral ties are also part of a broader and overlapping alliance involving Armenia, Tajikistan, Belarus, Syria, and Venezuela. Yet, above all things, both republics are also two of Washington’s main geo-strategic targets.
