Kazakstan would probably follow Russia, Indonesia and Malasia would follow China most likly because they like being nt invaded.
However some other questions or what about Australia., I personaly think they would follow America's example. Most likly so would Africa . South Korea and Japan may decide to go along with Russia or they may stay Nuetral.
Then you have Pakistane wich would go with China, not cause they like um but because they hate India. The whole of the Middle East(Iran,Saudi Arabia,Israel and all of them) would most likly be involved since it is on basicly thier continant ( if you want to use that phrasing) However I am not sure what side they would claim.
