As someone who has lived in China, no that’s not the case. Of course Chinese people can and do make high quality things, but there is a huge amount of incredibly poor quality stuff at all levels. As an example the floor of the flat I lived in fell through into the (thankfully empty) flat below two years after I left it, the building was less than 15 years old.

Partially its because of the real lack of regulatory oversight in China and partially because of a cultural sense of “ends justify the means” when it comes to business ethics.
