Something similar has been asked loads and loads of times. It’s not needed to investigate, just searching for previous discussions is enough. It sometimes surprises me that people don’t read one of the many times the same was asked before. That said, despite the same questions coming up many times there’s often multiple people who will gladly explain things. So I agree that it doesn’t make sense to complain about it. I’m a bit surprised that nothing would come up though. It really gets asked regularly.
Why do you assume the West? China often expands to other Asian countries. Or pretend to. E.g. after tariffs are applied to China you’ll often see a huge increase in intra Asia trade. Followed by different Asian countries heavily increasing their exports. Usually by hiding the true origin (tariffs are applied to the origin, not some transhipment place).
