> Same thing can be said about the US trying to overthrow the CCP during Mao when they banned food export
Did you mean when the US saved China from being obliterated by nuclear weapons by the USSR in 1969? Or when the US saved China from continued genocide by the Empire of Japan by almost single-handedly defeating the Japanese military in the Pacific? Maybe you mean when the US funded the build-out of modern China through trade & commerce and not only allowed them into the WTO, but openly invited them in (we got rewarded nicely for that).
> Invaded Chinese sovereign territory during the Korean war and got beat back into the current border of South Korea.
When the US tried to save the people of North Korea - the Korean War was a UN military mission - from half a century of extreme poverty, genocide and misery that continues to this day (and with zero human rights). With China on the opposite side of that equation, supporting the outcome of genocide, dictatorship, zero human rights, extreme poverty. Meanwhile South Korea became an affluent, liberal democracy.
> Supported a western friendly government during WW2 to take over China.
When the US tried to spare China half a century of extreme poverty, genocide and misery. China could have developed much faster and with human rights, as with South Korea, Hong Kong and Taiwan - and without the slaughter of tens of millions of people.
