"This book argues that the world entered a new cold war when Russia invaded Ukraine in 2022. While the United States and its allies are in competition with China, Russia, and their allies, this new cold war is far different from the old cold war. "The New Cold War and the Remaking of Regions" shows how this new competition will be multipolar and "multiplex," not a world separated into rigid blocs. Rather, secondary powers, small states, and even non-state actors will pragmatically pick and choose when their interests intersect with the great powers, preserving their flexibility and influence. The new cold war will play out in regional competitions that may lead to either peaceful change or conflict, but it will also vary from region to region and across sectors such as the tech economy. This volume contributes to the study of regionalism in international relations and is part of a new wave of scholarship that changes the focus of international relations from great powers alone to a recognition of the agency of others. Contributors address the new cold war and regional ordering processes through different theoretical perspectives: realist, liberal, constructivist, and critical approaches"--
