1 and 2 are the biggest reasons by far and matter a lot. Dictators are people too, they are susceptible as anyone to their minds being poisoned by too much nationalism. And even if it wasn't for that they would still view it as a way to get back flagging support from a nationalistic public(even dictators need a minimal amount of support from the population).

They do see Taiwan as an internal matter, that's the problem they don't recognize this sovereignty and don't like or understand Democracy. It's like Russia with Ukraine but they'll also claim Taiwan isn't a country because even most western nations technically don't recognize them. It makes me think we made a mistake not recognizing Taiwan as it's own country back in the 90s when China was less powerful.
