while I agree with your point,but see,USA tried and failed to drag India into this NATO thing.I don't think India is going to join in this grouping,atleast not until some open hostility by China against India.but I disagree with your comment on red.European NATO didn't get started with some European Countries which could evenly match SU.actually,none of Europe could stand against SU in conventional warfare.but they formed an alliance that could deter SU.same kind of concept is applicable here too.Japan,which presently lies as Pacifist,could form such a group if needed.though they're just a shadow of what they actually were,but even then,it is a formidable opponent.add it with might of USA,SK(which now seems kind of impossible,but see,even clash existed between NATO countries itself on various matter) and Vietnam,and you'll get enough power to deter China.nobody has to match one on one in every sector.they just have to make any Conflict beyond what we say,"Economic Feasibility",too costly that is unacceptable for opponent.that is the key.in present form,China can simply invade Philippines without much headache as their military is too weak and gain substantial amount of their land mass.but if you consider a group like mentioned,it can't.
