Turkey and Its Northwest Borderland Region: Interdependence Within Southeastern European Relations

This paper examines the relationship between Turkey and the countries in Southeastern Europe in terms of complex interdependencies. The study uses Buzan and Waever’s Regional Security Complex Theory as a theoretical framework, in which Southeastern Europe is viewed as a regional security sub-complex. Sectors of interdependence are reviewed and examined in relation to the region, including the military, political, economic, societal, and environmental segments. The study focuses on the economy in more depth and sees it as a sector the development of which can promote and increase not only social welfare but also the stability of the region. In this sector, EU Member States are considered key players with respect to the region, although Turkey may also step up its efforts in the post-Covid period. The EU and Turkey represent two different poles in Southeastern Europe, geographically and economically. Ankara has strong positions mainly in the Balkan countries that are more dependent on Turkey and have significant Muslim minorities.
