I definitely think that India embraces multipolarity because India also sees itself as a great power. They understand that they will always be second class in a US dominated world.

India not wanting to adopt yuan for payments is more of India not wanting Chinese currency to become stronger since they have a somewhat tense relationship. My expectation is that BRICS countries will figure out something along the lines of Bancor sooner than later, and that will solve the problem of moving away from the dollar as a trade currency. The other advantage will be that it will create a huge incentive for more countries to join BRICS.
