They are absolutely doing capitalist exploitaition. It's more a question of "is it worth it?" and "will they stop?". They have billionaires as a result of their liberalism, yes, but at least their billionaires can get prison sentences or death sentences for their crimes. Compare that to the US where billionaires have near-impunity.

I wouldn't call Chinese foreign policy "imperialistic" myself, you can see what a western liberal who directly worked with Chinese diplomats has to say about the issue, if you'd like. I would consider them to go to far in a non-interventionist direction, personally. They don't seem to have very much concern for international socialist movements, which makes them bad comrades (though we are also discussing whether they are comrades at all). I am posting in parallel, but to add to my other post in this thread, the CCP is not homogeneous either. It's very opaque, so it's difficult to get a fix on how things work, but there are both neo-Maoists and liberals inside the party (among others).
