It's an odd situation. They'll tell you they are but that's just a matter of "face" mainly. The Communists won the post WW2 Civil War sending Chaing Kai Shek's nationalist KMT off to Taiwan and slowly starved the population by trying to make city dwelling intellectuals into rice growing peasants and starving the country. Great Leap Forward my hairy arse. But even in the late 80s they were still all wearing Mao hats and scratchy coats and driving everywhere on bicycles and rural peasants were still regularly starving.Whatever they call themselves, they're not communists in any meaningful way.
So, eventually, the people went "f*** this" and Tiananmen Square happened. Just around the time the Berlin Wall was coming down and the USSR was breaking up and Romania was chucking out Ceausescu. Communism was collapsing.
With the KMT doing rather well in Taiwan manufacturing the world's crap the appearance of Communist victory on the mainline had to be maintained, and it is today in the Party's structure. There was no way the Communist name was disappearing.
The Economic philosophy was gone at that point though but, as per my earlier post on here, an authoritarian government is absolutely crucial to running a place as large as China. You can't do it without control. And with control comes zero freedom of speech and lots of disappearing people. And with the replacement of economic socialism with taking over the crap manufacture from Taiwan comes destroying the planet.
It's just slightly disappointing that @Swansman who has in the past been supposedly a socialist, ecologist and humanist is now defending a regime that is destroying the planet and human beings at an astonishing speed and who has in the past derided lockdown is defending a government that is still locking down. I guess the World Cup writing must have dried up.
