NK yes, China no.
Yes, more corruption than what is possible in India, although you will not know it.
You don't have communal riots in NK because no momins present, all NK walas were earlier buddhist or korean shamanists, and now they worship the Kim Jong clan
TLDR in authoritarian govts you don't have to fear left liberals, momins, commies, NGOs etc, you fear the almighty and omnipotent state apparatus.
secret police, normal police, your neighbors spying on you for govt, you spying on your neighbors for govt, for high tech places like China there are algorithms that will put you on some kind of list of the govt for objectionable jhumlas you put on your SM or Chat.
I am all for authoritarian govts and controlled media, heavy police presence, and subduing of momins and other anti india groups btw.
Provided i am a part of the state apparatus
