That's over a million square kilometers, involving Central and West Africa, South Pacific, the Far East, and other regions, achievements of decades of overseas colonization since Germany's unification, ultimately easily acquired by East Africa.
Clearly, East Africa doesn't see it this way. From East Africa's perspective, it was entirely a mutual and fair transaction. After all, if Germany hadn't sold these colonies to East Africa, they would have only been taken over cheaply by countries like England and France.
But now that the war is over, Germany wants to reclaim these colonies, East Africa certainly will not agree.
This is one of the major disagreements between the two countries. For Germany, given the final results of World War I, what Germany gained wasn't enough to offset what they lost, and the loss of these overseas colonies was particularly painful for Germany.
