India could offer to China that if they leave IOR to India, India will leave SCS to China.US is a declining power and if US wants to be happy being #2 then they might as well make a deal with China.
You cannot expect same support from Russia as from erstwhile USSR, a LOT of things have changed.
So you only have options, either 1) go solo or 2) go with US.
If incase 2) doesn't work then we have only 1), and we'll manage it now all thanks to recent developments.
India is pushing ahead with it's own interests in IOR and not US interests through the QUAD! You've got things horribly wrong! Stop reading propaganda!
