A more thorough explanation:

EXTRANATIONAL

Extranational is an adjective used to describe something that is beyond the territorial and governing limits of a country.

• A multinational corporation that operates in multiple countries is extranational.
• An international organization like the United Nations is extranational because it operates beyond the borders of any one country.

These examples illustrate the definition of extranational because they both refer to entities that operate beyond the boundaries of a single country. A multinational corporation may have headquarters in one country, but it does business in many others, making it extranational. Similarly, the United Nations is made up of member countries from around the world and operates in many different countries, making it an extranational organization.
