communist party of china is the preferred nomenclature, communist parties are usually "communist" first and whatever nation state second, see see pee is a western invention, maybe to scare boomers by reminding them of the CCCP but i'm not sure we have a memo or leak about why the switch was made.
people have mentioned older coverage when china was not the big scary enemy where capitalist media referred to the cpc correctly, but i don't have arbitrary 1990s newspaper articles at hand.
