Well, China, Russia, Iran, and North Korea seem to have a (fairly loose) "alliance of convenience" at the moment. "The enemy of my enemy", more or less.
Bartering some e-scooters for oil is hardly an alliance. Other than China, you just have a list of outcast countries on America, Europe, or the Middle East's sh*t list.
Hmm, I'm not sure trading is an alliance.
I doubt NK sent anything to Russia without payment in hard currency (gold).
NK was getting some reactor hardware from Russia. 'Unfortunately' the ship that was deliveing it, Ursa Major, went under in the Mediteranean.
