Host countries are nations that provide a location for international events, organizations, or foreign populations. These countries often welcome visitors, businesses, or refugees, offering resources and support to facilitate their stay. Examples include countries hosting the Olympic Games or World Expos. In addition to events, host countries may also accommodate embassies and international organizations like the United Nations. They play a crucial role in fostering global cooperation and cultural exchange, benefiting both the host nation and the visitors through economic growth and increased cultural understanding.
