Just as a point of geography, there are actually two Congoes in Aftrica. There is the country called smply "Congo" in the same way Egypt is called Egypt. Its capital is Brazavlle, and the country is bi-sected by the equator. Its highlands are home to the great apes. South and stretching east along and below the Congo River lies The Democratic Republic of the Congo. Its capital is Kinshasa. In my fiction, I used the latter as "The Congo", because the river was important in the story, and also because I don't think you would refer to the home of the apes as "The Congo", but simply as "Congo". But that's my peference, and, as has been said, you can pretty much go your own way. It's your story and it is fiction.
