With CPEC, Chinese Strategic Goals are defined in a manner that it is in China's primary interest to ensure that Pakistan remains on a steady economic growth path free from any law & order and internal chaotic situation. Any disturbances within Pakistan will directly effect China's plans of having short, direct and economical access to arabian sea as well as having it's naval presence there.
Any misadventure by India, in the above situation, will not be tolerated by China. Even Russia, which is relying heavily on China in forming a strong eastern block to counter NATO and which has recently openly expressed its willingness to improve diplomatic and military relations with Pakistan, will not stand any such move by India towards Pakistan. India has no other option BUT to resolve its differences with Pakistan and reach an amicable solution to the Kashmir and Water issues. The alternative will be very detrimental to India as China will not tolerate anything which comes in the way of it's CPEC plans.
So, in the fast changing scenario, India has to play ball and either join the group that is forming Russia-China-India-Pakistan-Iran-Turkey, or be at the receiving end by the remaining members of the group. India has to make this choice. There's no akhand bharat happening in the above scenario, however, there can most certainly be a ghazwa-e-hind, if India doesn't behave like a good boy.
