International relations (IR) is the study of relationships between countries, including the roles of states, inter-governmental organizations (IGOs), international nongovernmental organizations (INGOs), non-governmental organizations (NGOs) and multinational corporations (MNCs). It is both an academic and public policy field, and can be either positive or normative as it both seeks to analyze as well as formulate the foreign policy of particular states. It is often considered a branch of political science.
