Not to mention US helped China to fight Japan, and build hospitals,etc. US never took an inch territory from China when it had the power to do that.
Russia on the other hand took a huge chunk territory from China and invaded and killed countless Chinese, but, China loves Russia while always hated US, I could never figure out why.
read true history how Korea war started. and no, USA army did not enter China, they were surprised to be ambushed by Chinese soldiers there out from nowhere, then both started killing. china "volunteered" to start killing Americans first in Korea and USA never even entered china.
historically countries all had conflicts and wars, if that's where you're going for "USA did something to China", you can list what they exactly did. While you do that, please do not forget, Chinese killed each other over history and it's probably 1 million times more than whatever the western alliance did together. Not an excuse for any sides, history is just sad and bloody, but focusing on blaming other countries is barking the wrong tree, for the most part.
