China is a socialist country run by a communist party, where the working classes have supremacy.
How do you believe this? In what way does the working class have supremacy over the capitalist elite in China?
Communism, as described by Marx, establishes a strong power to replace the elites, but then removes itself to give the power to the people. A powerful ruling class is not supposed to be maintained, as it is in China. China is largely capitalist, with a rich and powerful owner class who command businesses, and have more political influence than the average worker. This is not Communism. I don't know how you fail to understand this. Do you just listen to propaganda and not try to understand things for yourself?
