Nope. There are numerous existing and possible varieties of totalitarianism. Communism refers to the variety that is ideologically focused primarily on enforcing human social and economic equality. In theory, of course, not practice.
Here’s the Wikipedia definition: “Communism (from Latin communis - common, universal) is a revolutionary socialist movement to create a classless and stateless social order structured upon common ownership of the means of production, as well as a social, political and economic ideology that aims at the establishment of this social order.”
China has in the last few decades drifted so far from this definition that IMO it no longer fits in the least.
I’m not sure what you mean by “a single and self-perpetuating dictatorship,” but if you mean China has an autocratic dictator, this is just no longer the case. They have a collective dictatorship by the Party leaders, but no single individual with the power of Stalin or Mao.
YMMV
Perhaps you should look up the definition of communisum:
com·mu·nism noun
1. a theory or system of social organization based on the holding of all property in common, actual ownership being ascribed to the community as a whole or to the state.
2. A system of social organization in which all economic and social activity is controlled by a totalitarian state dominated by a single and self-perpetuating political party.

Since that definition defines 'communism' as "stateless" no nation would ever qualify. That definition also seems to require a perpetual revolutionary movement be in existence.
