By contrasting different theoretical perspectives on regional integration, this valuable text advances our understanding of this important phenomenon in international relations. The volume contains theoretical considerations with empirical studies of integration efforts in many parts of the world including Asia, Africa, Europe and Latin America. Structured in four sections: governmentalist perspectives; power perspectives; constructivist perspectives; and neofunctionalist and historical institutionalist perspectives, the book offers important insights to theorists, policy makers, students and other readers concerned about world developments. It will also provide support for courses covering international political economy, international relations and regional integration, both at undergraduate and graduate levels.
