Even crazier is the fact they still do the annual meet-up with all the other "Communist of..." parties. I can only imagine how surreal the meetings must be, with the delegations of the dwindling People's Republics bumping with various of-shots of people too Stalinist to stomach joining NewLeft organisations.
Do such meet ups mean anything though? If they're anything like those international affiliations of social democratic, liberal or conservative parties, then they're just useless talking shops who hold some annual convention, pass a bunch of meaningless resolutions that say "hey guys aren't our platforms the best? Yeah, we are so awesome!" and then adjourn and do nothing for a whole year.
Also I wouldn't call them as sold as the South African Communist Party. At least they support the party closer to their interests. The ANC went full neoliberal under Mbeki and is now effectively more anti-union than Scott Walker.
