This edited volume brings together some of the most important scholarly perspectives – in the form of both journal article reprints and original contributions – on the structure and dynamics of the EU’s multi-layered relations with its Eastern neighbours within the Eastern Partnership (EaP) framework and beyond. In May 2019, the EU’s EaP – an ambitious and sophisticated policy framework, conjoining elements of cooperation and integration, with the EU’s six eastern neighbours, i.e. Ukraine, Belarus, Moldova, Georgia, Armenia and Azerbaijan – turned ten years. This anniversary, in conjunction with repeatedly voiced critique by scholars and policy-makers alike regarding the framework’s effectiveness and utility, led the EU to submit the EaP to a fundamental auditing and revision. Structured around both enduring and emerging issues in the broader EU-Eastern neighbourhood framework, this book provides a retrospective analysis of key structural and relational challenges, unfolding regional dynamics, distinctive forms of bilateral/multilateral engagement, whilst also offering a critical perspective on the contested future relations between the EU and its Eastern neighbours. Looking backwards and providing a critical and thorough assessment of the first ten years of the EaP in practice, this book thinks forward and gauges its many potential future avenues. This comes at a crucial moment, as the EU and its six Eastern neighbours are in search of new and mutually acceptable forms of association.
