Taiwanese airlines (China Airlines) had a
horrible safety record for a while, largely due to having mainly ex-military pilots from a culture of covering up deficiencies and hiding problems to save social standing and such. I would never fly on them as a result (they're probably better now).
OTOH, Evergreen/EVA Air has an awesome safety program and record, and is also Taiwanese. So, it's a cultural issue within specific airlines, not overall national culture. (Similarly, I think it was AirTran and a couple other LCCs in the US which had horrible safety culture, and Alaska has amazing safety culture.)
