The income generated from tourism forms part of the country's

The income generated from tourism forms part of a country's "invisible exports." Invisible exports refer to services that a country provides to foreign customers, such as tourism, consulting, financial services, and more. These services are considered "invisible" because they are intangible and can't be physically seen or transported like physical goods, which are referred to as "visible exports." So, when tourists visit a country and spend money on things like hotels, food, and entertainment, this generates income for the country, which is considered an invisible export.
