After the South African War, the Portuguese war reparations were actually transferred to the British by East Africa, allowing the British to exercise comprehensive control over the Portuguese economy. Coupled with the traditional alliance between the UK and Portugal, the British tacitly allowed Portugal's colonial expansion in West Africa.
This also served as a buffer between the British and German colonies. As for France, it was naturally impossible for them to strip the Vida colony from Portugal as they did in the past.
In fact, the British would not allow France to do so either. After suffering a huge loss in South Africa, Britain could only intensify competition with France in West Africa; however, France's power in West Africa was clearly too strong, so the conflict between France and Britain in West Africa was not small.
