Both Chinese and Indian land forces still get relatively little money vs other branches of the military but both also have huge numbers of men in service. I think both countries can be compared since despite all the claims about modernization it seems they still rely on throwing big numbers to the game.
It would be interesting to see what both countries landforces would look like if they dropped numbers to 400-500k... i'd imagine that at lest in PLA all obsolete equipment would disappear as they would have more money per unit.
It's not even comparable at all.
India had a giant standing army where everyone is assumed to be used at anytime, it's similar to US army except India is more backwards.
China meanwhile is similar to SK and has a short conscription system and a professional volunteer service system. The latter would be used for conflicts such as confrontation with border intruders or anti terrorism mission. The former are around as a failsafe so that the army can grow hugely if a world war starts, and also they do national guard jobs like forest fire fighting, disaster relief etc.
