Which of the following does the Council of the European Union NOT do?

The correct answer highlights an important distinction regarding the role of the Council of the European Union. While it does engage in international discussions, it does not represent the European Union at the international level in the sense of conducting foreign relations or forming treaties. Instead, this role falls primarily to the European Commission, which acts as the EU's executive arm and represents it in international matters. The Council's primary functions include passing European laws, approving the EU budget, and cooperating on aspects of foreign policy with other EU institutions, thus focusing more on legislative and policy areas rather than direct international representation. Understanding these specific roles of the Council helps to clarify its responsibilities and limitations within the broader EU governance structure.
