I have any number of critiques of China (Yeah I'm a Dengist, for Little Deng.) But they're winning and despite occasional misgivings, they're doing pretty well since Xi came in at reigning in the capitalists.
Also I have met people who have met Xi, both decades ago and now, and dine with his family. And they swear up and down that he's a committed Marxist and takes building Socialism dead seriously, whatever other critiques they may have. But he needs to manage the Nationalists/ National Bourgoise/ and Neo Maoist/ultra factions carefully, and that usually means the ultras get shafted.
Its an open secret that Sixth Tone is personally protected by Xi.
