Settle the border dispute peacefully, demarcate LAC properly, stop frequent incursions, recognize AP as integral part of India, start issuing proper stamped visas to the Indians from AP and Kashmir...............and then you have a peaceful neighbour cooperating with you in business & politics.
Or else, be prepared for India to stir up your issues in all international forums, first Tibet, then Xinjiang, soon expect us to de-recognize Tibet & Xinjiang as part of China, expect us to issue stapled visas to the people of Tibet & Xinjiang, and also kiss goodbye to the massive business/investment opportunities in India that you are pressing for a decade.
The way China is going, soon you will be finding us in your opposite camp and you guys sitting alone with two of your rogue poodles.
