India is irrelevant to China. It is not even worth the title of "enemy"This is why balancing is problematic, India is mortal enemies of china which Russia use to counter china.
What really fundamental are friendly relations with north Korea and Pakistan which is unlikely to change at any circumstances while having Russia nearby is like living near the tiger.
Just think about when reunification achieved and energy surplus( or autarky achieved) happened altogether, would china really need Russia?
