Eurasian so-called brotherhood is an ideology driven policy-making model and little short of a vivid dream on Kremlin's part. It's typical for Russians to push this argument into every other international talk. Infamous for being the vanguard, Dugin himself personally led talks to a number of countries such as Hungary, Bulgaria, Serbia, Turkey and Iran, over such vague promises, only to be disregarded by being irrelevant of today's norms.
Suggesting a brotherhood of such between Russia and China while in its' nature, describing China as a near-hostile nation gives way to an existential paradox on itself as China is what kept Russia afloat after 2014. But eurasianism won't mention such details. In any case, I can hardly believe India has a definitive place on that dream. One day, should India decide to be more than whatever it is today, it would need to stay non-aligned and innovate indigenous political and economy models as such reforms take decades to implement and being aligned to either parties would give way to foreign interventionism.
