as mentioned before, if india truly believed highly discounted russian oil was not durable, then might as well get it free until its gone.
( i do not rule out that putin may give trump a stern phone call that changes things)
china a bit trickier , given its exports to russia are where its profits are at a premium.

on a somewhat related note, india seems the country most ambitious to straddle the america\china polarization of trade, and i believe they will have\use\increase their gold reserve massively towards this ambition.
india will increase their naval power for one reason only, which is to have strategic leverage over china via a blockade (as needed) of middle east fossil fuel. as such, they could also extract huge favors from america in case of a china blockade of taiwan.
