I think we should do the opposite, increase your relation with neighboring countries especially when you have somewhat good economy and influence on world scenario. Why let China make their seaport as naval base where we can do that?
We are investing $ 2 billion in Afghanisthan which is too far and Pakistan lies in between, where as there are countries like Nepal, Bhutan, Bangladesh and Myanmmar.
Lets offer so much assistance to them they remain as our satellite(additional) states. It will increase our influence. At least we have to learn to become a leader of these country than as for permanent membership in UN. Mauritius is giving two islands, take it, develop it, establish base in Maldives, you will have another "unsinkable aircraft carriers" like Andaman and Nicobar near to Africa (near Arabian Sea).
Its the only way we can establish over influence on Indian Ocean which is going to be major factor in 21st century. We are churning out so many ships and aircrafts that by 2030, we may have 2-3 additional defense forces of size of small country like Bangladesh.
