If you didn't intend a parallel between 1930s Germany and 2019 China, there is, again in my opinion only, probably a better way of making your point.
1. Germany annexed the Rhineland, Sudetenland, and Austria using the justification of unifying German-speaking peoples under a single banner. The Chinese line for Hong Kong and Taiwan is the same -- you look Chinese, you are Chinese and to say otherwise is treason and will get you labeled an American lap-dog. I can tell you this firsthand as a Chinese-American and if you need a more concrete example, just look at how the Chinese treated Gary Locke.
2. Revenge for the perceived humiliation of Versailles was a core driving factor for the rise of Nazism in post-Weimar Germany. If you can give me another explanation for the state of Chinese-Japanese relations, I will eat my words.
3. Go on any Chinese social media site and the amount of nationalist rhetoric you'll find is quite disturbing. Having pride in your country is one thing, to insist on your national, racial, and cultural supremacy is another.
4. Google what's going on in Xinjiang and tell me that doesn't stink of something.
Maybe I'm wrong and just being an alarmist, and it would certainly be in the best interest for the world if I were, but ask yourself -- what are the stakes this time if I'm not?
