Meaning, there are people in China who are nationalistic, as there are in America. And these have enough of a Chinese over American view they would purchase an arguably worse product for their views.

Of course there are nationalists in China. I didn't argue against that.

  As for cultural exports, I think America just dominates the world in that regard. If you want to use that as a comparison China would have to have equivalent cultural exports to be a fair point. And as far as I know most people have no qualms with eating Panda Express, PF Changs, or small Chinese takeouts, which is a Chinese cultural export.

I don't think a few Americanized Chinese restaurants with American owners compare to my examples?

The cultural export power of America is precisely one of the main reasons why I sense that the level of anti-American sentiment in China is not nearly as bad as the anti-China sentiment in the US.

  I'm skeptical of that. I'd concede if you provided data but a quick Google search for AQI right now says the worst US city NYC is 54 AQI and Shenzhen is 56. Los Angeles is 33, SF is 19. (source IQAir)

The data is just me walking on any street in Shenzhen and almost never smelling any gasoline or feel the heat from cars.
