By establishing reflectivist perspective in IR, regionalism met the third wave in the end of the Cold War. From this perspective, scholars can apply Wendtian constructivism to analyze the new wave of regionalism so-called the regionalization. Hence, constructivist turn to the regionalism bases on the seminal book of Wendt, Social Theory of International Politics. In this paper, three cultures of regionalism corresponding three roles of enemy, rival and friend are highlighted. In the other words, the constructivism contribution to study the new regionalism focused on the concept of regionness relates to what states make of this notion. So, the structure of interactions in a region, in the light of intersubjective ideas, envisions three cultures including Habbesian, Lockean and Kantian, according three levels of regional complex, regional society and regional community.
