This book explores the timely topic of energy security and international relations between the European Union and the Russian Federation. Pursuing a constructivist-discursive approach, it empirically analyses a corpus of energy discourses involving policymakers and representatives of the EU and the Russian Federation. Exploring various discursive meanings assigned to the material and technical character of EU-Russian energy relations, the monograph underscores how the identities and interests of both parties are strongly affected by the norms and values which frame the individual energy discourses.
