Decent infrastructure (decent internet, not much if any brown outs/black outs on power grids) safety. black folks, and banging sisters, year round warm weather, I might recommend:
Colombia (Medellin), Panama (depends on where, they got hood), Senegal, 2 or 3 Caribbean countries, Bahia, Brazil (black AF, haha...northern Brazil)
all others, Philippines, Thailand, Kenya (Mombasa), Costa Rica (which can qualify as black as there are blacks there, San Jose or the coast. Limon is the blackest on the east coast of CR but they can be hood AF as well), Bali, Kuala Lumpur, Malaysia
all others with a winter or colder climate: most of the former communist countries in SE Europe (Hungary, Romania, Slovakia, Slovenia). Turkey is beautiful. Portugal. Lisbon has gotten too expensive, Porto isn't bad, but on the west coast, some small towns that have cheaper apartments. Lisbon got a lot of blacks (Mozambique, Angola and Brazil were former colonies, many blacks emigrate there since they already speak a dialect of Portuguese). Not a winter like NY or Chicago but definitely a jacket and sweater. Think of hmm...LA when its cold for LA.
If you got paper, Lisbon, Barcelona, Athens, Durban, South Africa (not that expensive actually but not cheap either), Dubai / Abu Dhabi (holla at me and I don't have paper even though I included it in the list..lol).
Big paper, Vancouver (Similar weather to Seattle, not as cold as other parts of Canada), Bahamas, Martinique, Auckland, Wellington or Christchurch in New Zealand, perhaps the nicest white people in the world as a collective. Macau (the Vegas of China), they move a little different as it was once a Portuguese colony now back under China's control.
Generally speaking, you are your passport. Black Americans are generally seen as American more aligned in their minds with white Americans than say...a Nigerian or Kenyan. Not that you won't get racism, white supremacy is a global thing but they treat blacks from America differently, 'better' differently than native African. If you are black Brit or Canadian similarly.
