The Evolution and Geopolitical Rationality of the Caspian Region with Establishment of Legal Status : Interaction and Convergence Behavior

Caspian Sea as the world's largest lake is an alive and dynamic geopolitical region, with a new identity that has both potential of Convergence and Divergence. The collapse of the USSR transformed the Caspian Sea from a pure geographic area to a geopolitical region. The Convention on the Legal Status of the Caspian Sea was signed and put an end to a number of divergent factors but the status of the Base lines and the delimitation of the central and southern section were not finalized and postponed to the future which may lead to a new divergence. Using descriptive analytical method and library resources the authors try to find an answer for the research question. The authors argue that the establishment of the comprehensive and long-lasting legal status of this body of water requires the formulation of objectives and strategies, via constructive interaction, convergence, confidence building, art of diplomacy and pathology. Continuing dispute over geographic values ​​and frequent changes in positions of coastal states reveals the necessity of formulation of geopolitical strategies.
