By the mental gymnastics they have applied to make Stalins brand of communism into their ideal they have actually learned to embrace authoritarianism.
They think that the only way that communism can be manifested is by first destroying the western capitalist society and they think Putin and Xi will help in this endeavor.
It’s quite delusional (as both are openly embracing capitalism) and quite the opposite of how Marx thought communism would take place, but that’s what they seem to think.
