The EU Institute of International Law is a graduate school in Berlin primarily engaged in education on broader issues of European Union law and policy. It described itself as a think tank. The EU Institute focuses on topical issues in international commercial law, and European law. The European Union is a major trading partner of the United States and Asia, and as the enlargement process of the EU continues a sound understanding of the many legal and policy questions that arise is imperative for any lawyer interested in international law.
