Answer
Supranational organizations are intergovernmental organizations that have authority over member states, such as the European Union (EU). Transnational corporations are private companies that operate in multiple countries, such as Apple. Supranational organizations can affect state sovereignty by limiting the power of member states to make decisions independently, such as the EU's Economic and Social Policy (ESP) which sets common standards for member states. Transnational corporations can affect state sovereignty by influencing the decisions of governments, such as lobbying for favorable regulations.
