Turkish-Iranian relations continue to influence as well as to be influenced by the transformations in the national, regional, and international contexts. In this process, bilateral relations between the two states are evolving both in substance and style to display new characteristics of cooperation and competition. The fundamental dynamic to determine the nature of this relational evolution is the salience of economic issues, which have come to dominate the bilateral agenda and dictate the terms of engagement between Turkey and Iran to a great extent. Nonetheless, concomitant with economic issues acquiring rather decisive influence on bilateral relations, three asymmetries have become discernible that need to be addressed for a politically safe and economically sound relationship.
