The real problem with Chinese parts is safety. The Chinese use sub-standard steel that doesn’t seem to be properly cured, creating weak spots that give at crucial points.

BP was trying to blame it on the Captain who headed their fleet, but it wasn’t his fault. He wanted all the Chinese parts replaced. I’m not sure what the outcome was, but it was a real problem for a while.
