‘The book is characterized by impressive depth of analysis, a convincing, functional structure, and clarity of presentation and argumentation. Moreover, it calls on future studies to envisage policy conditionality for other sectors of integration as well, though it remains to be seen whether the success of visa liberalization can be repeated. Overall, it has been an extremely enjoyable experience reading Florian Trauner’s The Europeanisation of the Western Balkans, and I am thankful for the opportunity to discuss this valuable piece of work.’Marko Kmezic, University of Graz, Austria, Southeastern Europe 42 (2018)
