It's quite the opposite in terms of how the US has treated them. In terms of actual behavior, China has never had a better friend in its modern history than the US. The US helped China vs the Empire of Japan, which had done unimaginably horrible things to China. The US kept the Soviets from nuking China in 1969. The US invested trillions of dollars into China's economy over decades. We've treated them more than fair, we've worked with them as traders, we've tolerated their aggressive hacking and anti-WTO trade practices for nearly two decades. The US is the sole reason China got into the WTO. We've gone out of our way to try to respect their sensitivities toward Taiwan for decades. The US didn't seek to conquer China, or annex parts of China, or invade China, or turn them into a colony of a superpower. We traded with them and they've successfully built the world's second largest economy on the back of it.
