I thought they were anti Chinese, even when I was in Vietnam, back in the 70s.
Vietnamese have a (long) history with China,
Like a thousand years worth.
The two countries share a pretty long land border, and Vietnam actually fought against China, a while ago.
I think the two won’t fight again, now that China is nuclear, but I also do not anticipate China to invade.
Vietnam is not a good country, for invasions.
