Well isn't it condescending to assume that Angola can't have reasonable safety laws while Germany can?
Germany is hardly immune to corruption (as a German speaker I am well aware of this) and that indeed was part of the reason why this loophole (placed there at the behest of German medical device manufacturers) was ultimately removed (thanks, EU!) while plenty of poor countries manage to have non-corrupt governments and reasonable protections in place in particular against the depredations of foreign companies.
As it happens Angola this week removed the laws barring same sex relations, making them more liberal than bigger and so-called "more developed" countries like Russia, China, et al.
