* AU: The African Union is a continental organization comprised of all 55 independent African states. Its focus is on promoting unity, cooperation, and development across the entire continent.
* CPLP: The CPLP, on the other hand, is a regional organization with membership limited to countries where Portuguese is an official language. This includes countries in Africa, Europe, and the Americas.
In essence, the AU represents all of Africa, while the CPLP represents a group of countries united by their linguistic heritage, not by their geographical location.
