In terms of an anecdotal evidence... My father used to work for molex, one of his biggest complaints were fixing the molds after they were sent to Chinese factories. They would try to deconstruct them and couldn’t put them back together (this was the 90’s, early 2000’s). So they would be shipped back to the US operations to fix.
Eventually, he ended up spending years training up Chinese to replace him (my father, in China). Molex moved much of its tool making shop to China and shut down most US tool and die making operations.
Anyway, China has people who are trained, on factory floors, who are there to reverse engineer processes.
This has been known for decades, companies don’t really seem to care or know (I guess that’s possible as they are outsourcing manufacturing).
I have no doubt this is designed across all their industries and systems. It’s in their interest to do this.
EDIT: I want to point out, there’s no longer a need for China to reverse engineer. US companies ship the designs straight to China. This is probably why we’ve seen China catch up so fast. We trained their workforce and now provide them all the IP before we build it.
