This article explores the legalisation of the Common Foreign and Security Policy (CFSP) of the European Union (EU) and its increasing use of sanctions. It argues that the breadth and depth of the numerous sanctions regimes in place shows that EU foreign policy is not merely an aspiration but produces law and legal processes which share similarities with those in the rest of the EU’s legal order. Further, the article examines the extent to which non-EU Member States in Europe have aligned themselves with EU sanctions. The argument is made that this is evidence not only of Europeanisation, but also crucially of a legalised foreign policy which has allowed Europe-wide, EU-led foreign policy to emerge.
