Portugal, just as Spain, did sabotage some of the scant amount of infrastructure built in their former colonies. From either perspective, blaming Africans or not, it was not extensive enough to effect much of the population.
Quantize, don't bloviate.
You said "Europeans didn’t use candles to illuminate their homes and businesses" Where they did not, it did not entail full blown urban power grids. Quantize your claim.

Again a question you conveniently ignored: < Now if whites had put up all this infrastructure as you claim, then why would Africans kick out whites just to "accept" chinese for infrastructure? The more significant you portray the infrastructure built by the former, the more you undercut this claim.
Now let's see what more you have to offer to built up your infrastructure of excuses for Chinese population invasion into Africa.
The infrastructure built by the whites was completely neglected when they left (have you seen photos of Mogadishu, Nairobi, etc.?). The farms of Rhodesia are probably the best most recent examples; they used to feed much of Africa and are now importing food while exporting refugees to South Africa (who stand out because malnutrition has stunted their growth). Otherwise, the improvements would have been in the cities with related transportation hubs (including airports), as well as industries (mines, for example). When you see the harvesting of diamonds in muddy pits by Africans today, and contrast them to the mines formerly operated by Europeans (or still operated by “white” companies), the difference is stark.
They are bringing in the Red Chinese to repair/replace the European infrastructure, without seeming to realize they are just becoming livestock of Red Chinese colonizers while their countries are further stripped of resources. Red China will have a free hand in abusing them, because the rest of the world is awaiting the finished products.
