While they certainly had some really bad practices in the past, and I am no fan of the Chinese government, I find it hard to believe (and condescending) that today they are so cartoonishly self-destructive.
I said government, not society. And extensive, by the way. I have worked with Chinese partners over months. There is a cultural difference for sure, and substantial parts of it that I find onerous, but nothing I would consider to be "foolishly self destructive". And this is all coming from a privileged position.
To the point where they will destroy products, livestock, equipment, etc; that would be thought to be for China's "enemies" ie: Japan.
It'll just take a moment for the message to get out, and then they'll be rallied to a new hatred, if they need be.
