The Chinese government is not a monolith. Neither is the Chinese Communist Party (CCP). Both entities, which overlap a LOT, are millions of bureaucrats. Many of whom are very minor players in small towns and some of whom are very powerful.
The CCP does have complicated internal politics, with “politics” meaning how groups reach collective decisions. Chinese society, government, and business is heavily based on personal connections. Your brother’s uncle’s neighbor’s friend matters a lot to you, and the size and power of your own connection network determines a lot of how your life goes. As such, at the highest levels of power you end up with factional leaders, each of whom sits atop a pyramid of connections who, directly or indirectly, owe their success to the faction head. And the faction heads each have legitimate policy differences with the other, as well as simple competitive lust for more money and power than their near-peers.
A LOT of what goes on between factions is malicious, at least to the degree that term can be applied to a group. Wang Chung’s group is going to do X precisely because that harms the interests of Kung Pow’s group, while advancing their own. Whether it’s sound policy for the nation as a whole is not necessarily very important.
Right now, in the last couple of years and next couple of years, we are all watching the current supremo Xi Jinping working diligently to make himself into a Putin-like absolute ruler for life, and along the way, his faction into the permanent ruling sub-class of the ruling class. Much has been done, and not done, that can be described as malicious.
I wonder a bit if the OP isn't mixing malicious with vandalism. When a burgler breaks into a store and steals cash & stuff, they at least gain the money they stole. So there's an exchange of gain and loss. The store is poorer and the burgler is richer. The burgler definitely wasn't considering the store's interests while doing the deed. That's malice.
A lot of what seems to go on in US RW politics now seems to me more like vandalism. Like breaking the store’s windows, trashing the interior, but leaving all the merchandise sitting there. IOW, they’re not trying to gain some tangible value; they’re just having fun destroying something other people value. That’s a different sort of malice.
What does the word “Malice” mean to the OP?
