I just saw a press conference with national security advisor Jake Sullivan, where he discussed diplomatic alliance with the African Union as a move that "will strengthen the G-20".

"African Union"? I never even heard of it till now.

It's basically a regional alliance of Aftrican nations, comparable to the Organization of American States in the Western Hemisphere.

I was particularly amused by this portion :

Quote
The historical foundations of the African Union originated in the First Congress of Independence African States, held in Accra, Ghana, from 15 to 22 April 1958. The conference aimed at forming the Africa Day, to mark the liberation movement each year concerning the willingness of the African people to free themselves from foreign dictatorship, as well as subsequent attempts to unite Africa, including the Organisation of African Unity (OAU), which was established on 25 May 1963, and the African Economic Community in 1981.[12] Critics argued that the OAU in particular did little to protect the rights and liberties of African citizens from their own political leaders, often dubbing it the "Dictators' Club".[13]

Ah yes, respected allies, that will strengthen the G-20, to be sure !
