This book explores the normative foundations of ASEAN and the EU. It revives the history of the two organizations in an in-depth narrative of the protracted arguments surrounding their establishment, legal integration and enlargement. While political actors used norms to legitimize their ideas for institutional change, the complex and dynamic nature of these norms also provided the breeding ground for contestation and, sometimes, institutional sclerosis and failure. Recasting these processes in an innovative English School framework, the volume makes a crucial contribution to the literature of Comparative Regionalism that goes beyond Eurocentric perspectives.

A seemingly never-ending stream of observers claims that the populist emphasis on nationalism, identity, and popular sovereignty undermines international collaboration and contributes to the crisis of the Liberal International Order (LIO). Why, then, do populist governments continue to engage in regional and international institutions? This Element unpacks the counter-intuitive inclination towards institutional cooperation in populist foreign policy and discusses its implications for the LIO. Straddling Western and non-Western contexts, it compares the regional cooperation strategies of populist leaders from three continents: Hungarian Prime Minister Viktor Orban, former Venezuelan President Hugo Chavez, and Philippine President Rodrigo Duterte. The study identifies an emerging populist 'script' of regional cooperation based on notions of popular sovereignty. By embedding regional cooperation in their political strategies, populist leaders are able to contest the LIO and established international organisations without having to revert to unilateral nationalism.
