EU Actorness in the South Caucasus: Possibilities and Limitations Despite significant institutional changes and refinements since its creation in 2004, the ENP (European Neighborhood Policy) remains a major tool available to the EU for providing incentives for reform and stability in non-member states through the diffusion of its norms and rules. Earlier studies, drawing on the Europeanization conceptual framework, have been mostly concerned about how and by which mechanisms compliance with EU rules takes place, rather than focusing on whether and to what extent it occurs. By contrast, this article assesses the actorness of the EU in three countries of the South Caucasus (Georgia, Armenia and Azerbaijan), viewing actorness as composed of three dimensions-capability, opportunity, and presence-enabling and constraining the aspirations of the EU to be an international actor in the South Caucasus.
