European Foreign Policy After Lisbon: Strengthening the EU as an International Actor

Following years of compromise, the Treaty of Lisbon finally came into force on December 1, 2009. This article analyses the new substantive law regulations and institutional arrangements of the Lisbon Treaty in the field of external relations and their impact on the effectiveness of the European foreign policy and the European Union as an international actor. For this purpose, this paper starts with analyses of the principle of coherence and continues with the reformed structure and legal personality of the EU, which was previously a serious challenge for the coherence of the EU’s foreign policy. Finally, this article examines the functions and implications of institutional innovations, namely, the positions of the High Representative of the Union for Foreign Affairs and Security Policy, the President of the European Council and the European External Action Service. This paper argues that the Treaty of Lisbon improves the preconditions for a higher degree of coherence in European external relations and strengthens the EU as an international actor, even if the success of the European foreign policy, especially in the field of CFSP, still depends to a great extent on the Member States’ willingness to cooperate.
