And honestly speaking I'm not sure myself if "tankie" should apply to China, seeing how most of their bad shit happend internally with the notable exceptions of Taiwan and Hong Kong, which are a stretch. There is a distinctive difference between Russia and China, despite both belonging to same political alliance and both have a dictatorial leaderships. Hating west/USA and loving either of them would make one a campist, but I'm not sure about that qualifyng as tankie. Naturally, most campists support both, so by that definition it would make them tankies.

While your definition does describe tankies as well, I always understood it to be a derogatory term for the general authoritarian communist/pseudo-communist block more so than applying to all national supermacists.
