also, communist party can't "partake in capitalism". little do you know about capitalism nor communism eh? go read some actual books, stop learning history from youtube and wikipedia, posting random sources copied from these so-called "objective" websides.
a socialist state means constant revolution, breaking down the system time after time like lenin and stalin's cccp (top-down) and mao's china (down-top). if they embrace the free market and base their administration on capital power, they either turn into a capitalist party or got cracked down and replaced by foreign power.
in ccp's case they've turned into a capitalist party since 1978. a clear evidence is that you can see some provinces declearing their bankrupcy.
