This paper aims to evaluate the trilateral relations between Turkey, Serbia, and Bosnia and Herzegovina. In the course of a proper evaluation of the growing dynamics of diplomatic relations between these three countries, it is important to assess relations at the presidential and ministerial levels. The research analyzes official statements, declarations, and agreements that envision the tripartite mechanism. Besides putting these official statements, declarations, and agreements into perspective, the research aims to assess the major implications, activities, and results of trilateral relations. It is significant to determine to what extent trilateral relations affect diplomatic relations, regional stability, regional cooperation, tourism, trade, and economic relations. This paper also aims to put the trilateral relations into perspective by explaining constructive and proactive Turkish foreign policy in the Balkans.
