I can not generalise at all. Chinese companies can be on both sides of the extreme.
But one thing is certain, there is much more natural selection involved with businesses. A factory producing low quality widgets will be evaluated incomparably more harshly by professional buyers than a customer facing brand selling them in the US.
There are bosses who learned to respect engineers, and there ones who didn't. The later keep loosing businesses, go from one master to another, until they hit the bottom, unless there is somebody who keeps bailing them, which is not rare.
I knew one dude who lost 3 businesses as an appointed director, but each time he failed, his well connected uncle was ready to refer him to then next "good friend."
In China, "the boss" is much more of a social/hereditary class than a job, much more than it is in USA. The majority of the economy is still kept by the people called "the first generation money," though they been slowly losing their dominance in the economy over decades. You can imagine, a lot of the first gen wealth were former party bosses themselves, or their relatives.
Out of that class of people, there are some good bosses who were taught by hard life experiences, and ones who weren't. I myself recommend people not to risk and try to find an employer whose boss is not coming from that social group.
