India follows the policy of Mahatma Gandhi. We don't want to quarrel with any of our neighbours including Pakistan. Unfortunately Pakistan has developed an enmity with India which is totally unwarranted.
As far Srilanka, it is a time tested democracy believing in rule of Law. If the Sinhalese leaderships shows maturity and take all the ethnic minorities with them, it can prosper very well.
India is on the verge of finding a solution of the border dispute with China and once it is done, we may not have any problem with China. Already China has recognized Sikkim merger with India which is a great development.
Future belongs China, India and other nations in Asia. A prosperous Asia is good for the entire world.
All the best
