I like the Chinese people, Chinese history, and loved visiting. My dad was a hippie with lots of books in the house in support of China's communist revolution.

That said I think the big one is that China did not keep their word to the UK regarding Hong Kong. So that moves them to 'suspect' as far as trust goes with Western nations.

I think their secret police stations imbedded/hidden in western nations and their supposed use for secret forced repatriation of people really soured a lot of people/nations on trusting China's behavior.

They are doing a lot of saber rattling regarding Taiwan. Lots of flights as well as naval movements that have raised concerns.

People really don't like what they believe has been happening in Xinjiang.
