Asia's Regional Architecture transcends traditional international relations models. It investigates change and continuity in Asia through the lens of historical institutionalism. Refuting claims regarding the demise of the liberal international order, Yeo reveals how overlapping institutions can promote regional governance and reduce uncertainty in a global context. In addition to considering established institutions such as the Association of Southeast Asian Nations and the Asia-Pacific Economic Cooperation, he discusses newer regional arrangements including the East Asia Summit, Trans-Pacific Partnership, and the Belt and Road Initiative. This book has important implications for how policymakers think about institutional design and regionalism in Asia and beyond.
