I should probably get to writing a post.

EDIT - As a minor correction Byrd, I'd like to toss in China has only really traded weapons out with those it considers allies, usually those who ended up in the former ASB or the current Third International. And in those cases it's usually been "last year's model", although the CP1960 hasn't been updated in fuck-a-long time so it's stopped being relevant to that rule. The only exception to the Chinese rule in so far has been the Ethiopians.

If we're rolling on the presumption the US was briefly a member of the Chinese socialist club and then left for unexplored reasons in this new vision of the US then it's likely anything sold to them as surplus likely stopped coming the moment they left the International (at around that time enough people were pissy at the US for their annexation of the Cascade territories they were going into a trial of sorts). So they'd be dumped back into having to provide for their own.

I just wanted to throw that out since I noticed that in your post. I'll have to read it in earnest in a moment.
