Why does China hate America?

--  China dislikes America because America supported the right wing Nationalist Chiang Kai-Shek (a war lord, criminal allied with the Green Triads, a dictator) from the mid 1920's.  America supported the Nationalists in the civil war between 1945 and 1959 and also supported the Nationalist government when they moved to Taiwan in 1949.

-- The US has had trade embargoes on China in the past and currently is opposing China's claims on the Spratly Islands in the South China Sea (islands contested by over 5 nations) and America is using its navy to provoke matters.

you should say that American government has been trying every means to encircle and suppress China's development since Biden takes office ,US is trying to create an Asian NATO to meet china's challenge ,Japan ,Australia,India may become member of Asian NATO ,What's more ,American media is trying to tarnish china's image using Uighur lies to subvert China's government ,in fact ,The Chinese government don't carry out genocide against Uighur at all ,this is trumped-up allegation of western media ,they are adept at concocting story to cheat the general public ,

in my opinion , western media just want to divert people's attention away from its bad economic situation from Western countries ,  and instigate Uighur to rise against Chinese government ,the last thing western countries see is China's rise ,How far do you think the relationship between China and US will go ,How much do you think such a relationship will worth ,it's no surprising that Chinese people dislike American people ,

I don't detect enough tension between the nations to give your opinion any merit.

It does not. It wants to be be top economic power. America is trying to stop China. Classic Thucydides trap
