American living in China, here for 10 years now. Even before the current tensions, as an American visiting China, you'd be likely to feel like you've stepped into another planet on entering. China is just so utterly different, and if you are non-Asian, you attract a lot of Chinese eyeballs from everyone from young children to Grandpa's, as they are just generally curious about foreigners. Everyone openly refers to you as "foreigner", like "hey look at that foreigner over there". On top of that, they are security conscious here in China. In 10-years in China, I've never found myself in a place where I've felt unsafe. Frankly, having personally been in serious danger in America a few times and further, my little brother got robbed, shot and killed and died in the middle of a street. I can't say the security here in China is a bad thing. The society in China prefers to be secure and have cameras everywhere, and it seems to be working for them.<p>So, I think those factors I mentioned above can naturally magnify incidents which are probably just going to happen to a foreigner here in China regardless, especially if the foreigner is already a bit concerned about anti-American sentiment. As far as the anti-American sentiment. I can remember it happening a few times and this is probably the worst it's been for Americans. But, I can remember times where anti-sentiment for Japanese appeared much worse. Locally to where I live, some Chinese nationals vandalized a few Japanese cars and stores. I don't feel like it's come close to getting that bad for Americans, yet. And largely, I feel like the Anti-American sentiment from Huawei and trade tension stuff hit a spike a few months ago, and people have pretty much moved on now.
