This special issue covers emerging power’s policies towards international global and regional organizations. Do emerging powers use regional organizations as leverage against the global order or institutions? Are they used as a collaborator between international and regional politics as a sort of check and balance? Or is this an indication of regionalization of world politics, and thus, emerging powers seek to establish their own sphere of influence? Most of the states in the world are members of global institutions and also some of them have established their own regional institutions. Since the mid-Cold War years, there has been a tendency to form regional organizations in the name of regional economic development and particular identities. It is evident that most emerging powers seek to provide an alternative way of politics against the Western hegemony. In current world, security is not just military protection but extended to numerous aspects, and there is no way that one or a set of states can provide such security. Regional integration, economic development, and political and military alliances have played a significant role in the state’s foreign policies. The current international system is a “not yet fully established multi-polarity” as there is no consensus on which states constitute a polarity or how many polarities we have in world politics. It means that almost every single state in current world politics instrumentalizes international institutions to protect their national interest and security via bi-lateral agreements, regional organizations and international (global) institutions at the same time. While doing that, they place regional institutions at the centre, do not withdraw from the global institutions, and restrain themselves from signing bi-lateral agreements for specific issues. This thematic dossier is coordinated by Professors Rahman Dag e Özgür Tüfekçi and include an editorial and 25 articles.
