International lawInternational law (also known as public international law and the law of nations) is the set of rules, norms, and standards generally recognised as binding between states. It establishes normative guidelines and a common conceptual framework for states across a broad range of domains, including war and diplomacy, economic relations, and human rights. International law differs from state-based domestic legal systems in that it is primarily, though not exclusively, applicable to states, rather than to individuals, and operates largely through consent, since there is no universally accepted authority to enforce it upon sovereign states.
International relationsInternational Relations (IR) are the interactions among sovereign states. The scientific study of those interactions is called international studies, international politics, or international affairs. In a broader sense, it concerns all activities among states—such as war, diplomacy, trade, and foreign policy—as well as relations with and among other international actors, such as intergovernmental organizations (IGOs), international nongovernmental organizations (INGOs), international legal bodies, and multinational corporations (MNCs).
International organizationAn international organization, also known as an intergovernmental organization or an international institution, is an organization that is established by a treaty, or is an instrument governed by international law and possessing its own legal personality, such as the United Nations, the World Health Organization, Save the Children International, and NATO. International organizations are composed of primarily member states, but may also include other entities, such as other international organizations, firms, and nongovernmental organizations.
