The conversation around China will take a minute, so I'll skip ahead to your second paragraph and circle back to do your statement justice.
The people you describe as "tankies" do not exist in any reasonable number. You are extending a belief in some aspects of anti-western sources as full blind dogmatism. Secondly, in order to even consider oneself a Communist in a western-dominated website means exposure to constant western-narrative, the idea that eastern propaganda is much more effective is more of a smokescreen to avoid discussing hard topics than anything else.
As for the PRC, they absolutely aren't Anarchist. They are, however, Marxist-Leninist, and Socialist. They have a Socialist Market Economy. Their Public Sector has supremacy over the direction of the Private Sector as key heavy industries the Private Sector relies on are entirely State Owned, and the Private Sector itself is trapped in a "birdcage model" whereby the CPC increases ownership and control as Markets naturally form monopolist syndicates.
This is entirely in line with Marxism. Marxists believe that markets naturally centralize and form monopolist syndicates ripe for central planning, and thus are more efficient vectors for growth at earlier stages in development, but that as they centralize this becomes less efficient and public ownership and central planning takes priority.
I recommend the article Socialism Developed China, Not Capitalism.
