There are exceptions but your comment does apply. If you buy your RD hanger or your surgeon gets your prosthetics made by BMG Ti who make bicycle parts/hangers as well as parts for Airbus, GE, etc., you don't need QA/QC engineers checking things out as they are AS9100 and NADCAP certified. We built project QA/QC teams with Chinese engineering consultants to help as you have to watch everything all the time as these were one off contracts. Coming from a smoke stack industry we all looked at moving operations to the PRC and to make your point, each province has water quality laws very similar to our EPA here but there is zero regulatory enforcement. As late as last year you can not drink the tap water anywhere, even in the $$$$ hotels in Beijing and Shanghai, and you have to have a cleaning plant for river water for use in your smelter but you will save money as you can dump your highly contaminated waste water (lead, arsenic, cadmium, etc.) back in the river.
Fortunately for us the big pharma, Bayer and others, have to do it right.
