Nazi Germany adopted many of their policies based on US laws, and used American companies like IBM to track where Jews were living to better send them to camps, and the United States created camps to house Japanese Americans. The 13th amendment doesn't outlaw slavery, it puts it into the constitution by saying it's okay when used as punishment (prison labour) and then created a system which quickly became overpopulated with the very demographic that were being used as slaves previously. Plus there were still slaves well into the 1960's who didn't know they were freed, and while the States does have better censorship laws, they do a pretty good job not teaching/talking the darker side of history so most people don't know about it.
I'm not going to pretend that China is some beacon of liberty or freedom, I joke about the fact that an iPhone from China wont have the Taiwanese flag on it, but to pretend that the United States is that much better is just not being honest. You don't become and maintain your position as the largest power in the world without getting your hands very dirty, which is why there's a long history of interference, colonisation, support for terrorist groups and funding going to dictatorships/more violent regimes than China, and even war crimes that are attached to the US which are often swept under the rug. It's similar to actions taken by the UK when they were in that position until they basically did a major rebranding after WWII. Japan undertook a major rebranding as well, so did many other western nations, especially the former colonial powers (France, Spain, Belgium, Germany, etc).
Honestly, this is isn't even really politics, it's just world history.
China is over reported on by much the West in order to otherise the nation and deflect attention. Again, they have a lot of dirt on their hands as well, they're really not all that different from most other countries, it's just a bunch of people with red hands pointing at each other. Increased interaction between the West and China is probably better for everyone anyway, if we can learn more about each other and our different cultures, we're likely to find there's a lot more shared values than not, you just have to parse through the bullshit.
