In fact, in Ernst's previous life, Africa had a Southeast African Common Market organization, officially called the Common Market for Eastern and Southern Africa, with its secretariat located in the capital of Zambia, Lusaka.
And the reason why this regional organization led by East Africa is still called the Southeast African Common Market is closely related to the current political landscape of the African continent.
East Africa is a unique country, occupying a significant portion of Africa's area, and its territory covers large tracts in the eastern and southern parts of Africa.
Thus, using Southeast Africa to encompass the surrounding countries of East Africa is most appropriate.
Neither the East African Common Market nor the Southern African Common Market can achieve this effect.
