I'm not the person you're replying to, and I don't have the evidence you're asking for. However, China isn't stupid. Rather, they've often shown to be rather cunning, and it's impossible to know all the times they may use their weight and nobody notices. I'd liken it to cold war era techniques from the US and Russia. Both sides would often do things wrong on purpose just to muddy the waters or throw red herrings. People at the time thought that the US was clumsy and stupid when a top-secret document was "accidentally" leaked, but it was done on purpose to track spies, waste Russia's resources, etc. I do not put it past China to have multiple prongs here, with the clumsy antics simply a smokescreen for the real propaganda. Obviously, this cannot be proven, but like I said, there are lots of lessons in history of this being the case with other states. They have lots of textbook examples to follow.
