There are fewer and fewer of those all the time, though. Manufacturing is now starting to move to Africa because Asia has become more expensive. I don't think there's anywhere left to go after Africa.
More get created though every time one of those former countries undergoes a regime change of some sort. The types of countries where you can get slave wage labor aren't exactly known for their political stability.
Large factories require some level of political stability to protect the capital. Also, a functioning power grid is critical. That has been a blocker in many areas of Africa as I understand it.
