"This brilliant book moves the study of interregionalism and regionalism into unchartered terrains. By escaping EU-centrism and combining theoretical diligence and contextual sensitivity, it provides an outstanding example of what research in this field should look like."Fredrik Söderbaum, University of Gothenburg, Sweden."Meticulously written and perfectly timed, this book offers an incisive view of the unintended consequences of interregionalism. A must-read for those seeking to decentre EU studies or striving to understand the unintended aspects in EU external policies and international relations more broadly."Olga Burlyuk, Ghent University, Belgium.
