I don't present China as universally positive, I have drawn a clear line between socialist countries that are generally working towards a better society, imperialist countries that have been declining and are a net drain on the world, and non-socialist countries in the periphery that ultimately are progressing, albeit not necessarily as much as they could be if they were socialist.
There's also the fact that we aren't at all on the same page when it comes to dialectical materialism as being the start point for any genuine analysis, and as such I tend to reject framing that involves metaphysics.
