True countries interests often change with time and situations. In fact there was a time Japan was our nemensis in Asia(farrrr more than like China today) and China was our best friend/main ally in Asia back then. Same with the U.S.S.R , we,france, U.S were actually allies with Russia against Nazis germany during world war II, and there were even lots of weapons sales/help from the west to Russia during this period. Just google it and you wil see the west helped Russia with weapons/euipment against Nazis germany. China became buddies with Russia after the war and Japan became best buddies with the U.S/west after they lost. China also split with Russia later(fought a border war wih Russia, and it almost even went nuclear when Russia threatened to nuke China, it was ironically the U,S who warned Russia against any such move.lool)) and became buddies with the U.S(still under Mao i must stress), then after the fall of the U.S.S.R chin again became buddies with Russia until today and a rival to the U.S/west again, we dont yet know when/if China will again become rival with Russia(depends on how things play out in future and how their interests change), you can never rule anything out in geo politics. There ARE NO PERMANENT FRIENDS JUST PERMANENT INTERETSTS.
Thats why i LMAO when some chinese members here claim Russia is their ' iron brother and long time friend'.
Old boy how naive they are.
