I think it comes down to fear, envy or jealousy. For example I’ve noticed a lot of (rich) folks in Hong Kong hate the “mainland”Chinese because they’re so rich.

Then in Vietnam there is a strong anti-China sentiment because of the tenuous relationship with China colonizing Vietnam for so long.

And the Koreans hate the Chinese (the slur is to call a Chinese person a “짱께”to perhaps mock their language) because China is the powerful dominant country (중국 literally means “center country”), and also because Koreans want to build their own distinct culture (even though Confucianism and many scholarly traditions are adopted or borrowed from the Chinese).

Americans are anti-China because America sees China as an economic threat. I don’t fear World War 3 because in fact, the future warfare will be an economic one, not a bloody one. Also a war based on ideology.

Morale of the story:

I’m not afraid of China. In fact, I admire their brazenness, their “lack of standard morality”, and their long-term vision.
