Supranational organizations, such as the European Union and the United Nations, influence member states by promoting adherence to common standards, laws, and regulations. They facilitate cooperation on transnational issues, including trade, security, and environmental protection. Member states often cede a degree of sovereignty to participate in these organizations, which enhances their collective power while imposing constraints on individual nations' actions. This can lead to strengthened regional stability but may also engender tensions between national interests and supranational commitments.
