Tehran and Moscow: Alignment and Divergence in the Caspian
The complexities, converging interests, and persistent tensions marking Iranian-Russian relationships are evident in their policies toward the Caspian Sea region. Iran and Russia are the two largest countries that border the sea, the world’s largest inland body of water. The Caspian region therefore provides many opportunities for diplomatic, economic, and military engagement between Iran and Russia. Some issues of mutual importance relating to the Caspian include the Nagorno-Karabakh War, the Afghanistan and Iraq conflicts, NATO partnerships in the Caucasus region, and the construction of trans-Caspian pipelines.
