101Under Article 3(5) TEU, the European Union is to contribute to the strict observance and the development of international law. Consequently, when it adopts an act, it is bound to observe international law in its entirety, including customary international law, which is binding upon the institutions of the European Union (see, to this effect, Case C-286/90 Poulsen and Diva Navigation [1992] ECR I-6019, paragraphs 9 and 10, and Case C-162/96 Racke [1998] ECR I-3655, paragraphs 45 and 46).
