Regionalism has emerged as a significant phenomenon within the international relations system post-World War II. Scholarly debates concerning the emergence of regionalism are divided into two principal schools of thought. The first group emphasises internal factors within the region itself, arguing that the driving force behind states within the same region coming together to form cooperative frameworks arises from the specific conditions, factors, and interests intrinsic to that particular region. In contrast, the second group focuses on the international system, particularly highlighting the global economic and political structures that developed after World War II under the leadership of the United States.
