Arms export control measures are an important tool to defend the universality of human rights, democracy and to prevent conflicts. The European Union (EU) has a long tradition in striving towards these goals.One of the most important outcomes regarding such is the 2008 Council Common Position (CP) defining Common Rules Governing Control of Exports of Military Technology and Equipment Common Foreign and Security Policy (CFSP). This article focuses on the implementation and effectiveness of this CP. In particular, it investigates whether EU countries have applied and enforced human rights principles in arms export practices following the approval of the CP or whether a promarket and pro-export approach have prevailed. In this way, it fills a lack of organic analysis on the impact of the CP. Secondly, for the first time, it compares EU-level regulation impact with that at the global level, in order to assess the ‘net value’ of the EU regulation at the international level also from a diachronic perspective. Lastly, a comparison with the national level offer suggestions for mutual reinforcing. By using quantitative methods, the research aims to offer empirical evidence concerning the EU arms export control regimes and their effectiveness and to contribute to the present debate about the means at the EU’s disposal to defend the universality of human rights and promote democracy.
