Regional organization members: European Union. These memberships are not automatically assigned to every constituent country.

Keep the relationship clear.

APEC uses the term “member economies.” UN observer states appear separately from members. Country display names follow the connected reference catalog; the linked official roster is the authority for formal membership names and status.

These seven lists are a selected reference, not a complete inventory of all world affiliations. They add context to the country stories and do not change index scores.
