It's not just China though, you approach other socialist countries the same way.
You say China's problems aren't static or permanent, but you don't append such disclaimers or framing to issues outside of socialist regions.
I don't see China as anti-imperialist, but I'll drop the words "imperialist" and "fascist" altogether for the purposes of this discussion since we use it to mean different things.
Not everything is always changing significantly, some things can stay the same over time, but to answer the question, I'd say I see state surveillance, suppression of criticism, censorship, and things like that getting worse in China. Though this is kind of something I see happening globally, I'm inclined to believe this is worse in China because it's already etched into the system at a scale more prolific than in the west.
You can routinely find criticisms of America online but China censors this. You do not personally take offense to this because in your view the capitalist should be suppressed ("communism is the dictatorship of the proletariat"), but I do. I will also say that it is this framing which makes it such that one has to be a capitalist in order to criticize the Chinese state (and thus be censored), but this isn't true; I'm not capitalist but I would certainly criticize the state. I am staunchly against the notion of a dictatorship altogether, but this is something not everyone is uncomfortable with, I suppose.
My issue is that you don't frame away the negatives that you mention of non-socialist countries as being part of progress or being actively worked on the way you do for socialist countries.
I don't see China as being innocent and I retain that China is violent and aggressive when it finds the opportunity, and I've seen examples of this prior but I'd have to research to get into that w citations.
