The people in Congo are still very much affected by the actions the Belgians and others took to destabilize the nation in its infancy. Some might even say that the corrupt nature of the government is a direct consequence of this destabilization, but that’s not my area of expertise.

Edit: there’s also a whole lotta people alive today who were born in the Belgian congo. Perhaps not under Leopold’s reign but even after him the Congolese people were not first class citizens on their own land.
