Calm down, all in due time. Until the U.S. and the West in general can no longer intervene in the break away countries that was India, it is not in China's interest to break up India. Otherwise there will be turmoil in their neighborhood that will divide their resources and attention from their ascend. In two decades, the U.S. will slip into number two. At that point, they will contemplate fracturing India into multiple countries. Until then, a single India draws the least amount of energy. Even with the Quad, India is not yet a protectorate like Japan, so no U.S. military base in India as yet. It is the best outcome for China now.
