As someone who works in supply chain, I get what you’re saying, but Chinese material is always suspect, and the certs aren’t worth the paper it’s printed on. Having said that, Boeing willingly moved to Chinese suppliers to “save money.” I see it all the time. We move something to China and it works for 5 minutes then they start making it cheaper/shittier and we have to go back to our original supplier who then marks up their price as a fuck you to us for moving it in the first place. These MBAs are all about cost saving, and don’t give 2 shits about the big picture.
