Then your argument is not about whether or not china is state capitalist but about whether or not the Communist Party of China is earnestly communist and truly represents the working class in its political aims. That is an entirely sifferent question and is not much affected by whether or not they have state run enterprises.
These are not arguments against accusations of state capitalism. State capitalism doesn’t mean that stuff isn’t state owned, or that the state doesn’t crack down on billionaires.
State capitalism refers to the idea of a state owning the means of productions and engaging in capitalist practises through state owned or controlled enterprises. Saying that the state owns companies in china is like… perpendicular to the argument to whether China engages in state capitalism. These links are mostly irrelevant to the question.
State capitalist does not imply such a thing. State capitalism is whem the state does capitalism ehich it is perfectly possible to do in a way where it is attenpting to forward a communist aim. This was the case in the ussr.
