I imagine the processing tradition in the eastern Bloc was less sophisticated and picky than the Iberian/Mediterranean just as a result of the fact that only canning the good bits might have been a luxury they couldn't afford. How about other geographies and the standards of their tinned fish? I feel for no rational reason like something from Korea/Japan would be beyond reproach just based on reputation for national persnickitiness and affluence, whereas China might cut corners since tinned fish are not a traditional part of the cuisine that take pride in... But how about stuff from Thailand, or the Philippines? What about mid-Atlantic stuff from the Azores or Canaries? Any tinned fish from the southern hemisphere that is worth tracking down?
It's not just the processing in the "eastern block". The quality of the fish is poor.
Portugal and Spain are well-known for the high quality fish and it is treated with respect. Portuguese sardines are widely considered to be the best.
Canned fish is as traditional in Chinese cuisine as anywhere else. It is very popular. It is the only canned food sold in most stores. Some is excellent; some less so.
Thai and Filipino canned fish is very controversial. Poor working conditions; accusations of slavery. Your choice.
