I don’t want to be rude but the way you phrase your questions sounds a lot like you have a certain opinion about Russia and China that you want us to confirm.
I don’t think we have an expert on Russian and Chinese law here so all we can do is google stuff for you.
From the Wikipedia article it seems like at least Russia has a functional legal system (though one that works slightly differently from the ones we might be used to). The expectation that the government decides who is guilty regardless of the truth sounds like an exaggeration born out of an „us vs. them“ argument, similar to „democrats kill babies“. I‘m not an expert though, so don’t listen to me and instead look for independent sources.
I guess one of my subquestions is do they ever really need to dismiss or is an acquittal they don’t want actually possible?
