More than 10 years ago in Europe, there have been some discussions about whether it makes sense to have business with a government, which seemed to lack in respect for human rights. That topic went under, because profit and stuff. And as it turns out, might have been worth the effort to first have a serious international debate about human rights (and also about international system of law, which doesn't move borders based on who scares who the most), instead of hoping that a bit of wealth will not fuel imperialist ambitions, huh?
Personally, I still think that there should be a shift in foreign and trade policy, to firstly work with societies, which stand for a modern civilized world, even if that may perhaps not be as great a deal as with some shady dictator in Africa. At least in case of Prussia, e.g. helping a partner in Africa getting cold warehouses running (something, which is a rarity in some regions), that could be done with some equipment from here (ergo even helping local population with jobs), while helping the population there with sustenance and perhaps even within years so much economic growth (including exports), that the folks there can afford some imports themselves, such as from Prussia.
