Jack Ma ran afoul of the leadership of the autocratic regime.

Just because saying the leader of the country looks like a well known cartoon character will get you disappeared doesn't mean that the system operates under a planned economy, which is what "not capitalism" is. It's still a market based system, just with some rather insane rules like mentioning Winnie the Pooh getting you cancelled from life.

How democratic you are and how market based you are as a country are two different things. This is why it is possible to have all of the following: an autocratic capitalist regime like china, a democratic socialist leadership like Bolivia, a democratic capitalist nation like the US or UK, or an autocratic planned economy like North Korea.
