"Avoiding the Western-centrism trap characteristic of rationalist theories of regionalism, Jürgen Rüland cleverly builds on current constructivist theories of norm diffusion to explain how foreign policy stakeholders in Indonesia have responded to external ideational and normative pressures seeking to Europeanize ASEAN. With intelligence and nuance, he offers an essential study of comparative regionalism and Indonesia's role in the ASEAN Charter."—Randall Schweller, Ohio State University, Editor-in-Chief, Security Studies "The book makes a substantial contribution to our understanding of Indonesian foreign policy and ASEAN regionalism. It is an important piece of work, and I found the author's arguments convincing and compelling."—Moch Faisal Karim, H-Net Reviews "In addition to its important theoretical contribution to regional integration studies—highlighting the complex processes of localization and that of omnidirectional diffusion, signifying that Europe is not the sole source of inspiration about regional integration—Ruland's book also provides colorful insights into the dynamics of foreign policy decision-making in post-Suharto Indonesia....This book is a welcome addition to the literature on Indonesia's foreign policy and ASEAN"—Dewi Fortuna Anwar, Contemporary Southeast Asia "[T]he book is a very welcome addition to recent, more theoretically-informed scholarship on foreign policy in Southeast Asia and ASEAN Studies, and will be of interest to both scholars and policymakers interested in this region."––Stéphanie Martel, Pacific Affairs
