The Islamic Republic of Iran's government has persistently sought to secure its interests in the Caspian following the collapse of the Soviet Union; there have been a number of political and geopolitical barriers depriving Iran from attaining an important part of its interests in the Caspian. Using descriptive-analytical approach, this paper seeks to academically discuss these barriers and suggest measures overcoming these problems.
