The International Civil Aviation Organization (ICAO) is a specialized agency of the United Nations that works to promote safe and orderly international air travel. It has 193 member states, each representing a country that participates in the global aviation system. These member states collaborate to establish standards and regulations for civil aviation, ensuring safety, security, and efficiency in air transport. ICAO member states are responsible for implementing the organization's policies and guidelines within their own territories. They also participate in various assemblies and meetings to discuss aviation issues, share best practices, and develop strategies for future challenges in the aviation sector.
