Not even that, even China is holding on to a large piece of Kashmir which they captured during India-China war in 1962. The dispute between India and China is so old, that it is not possible that it will get under shelves just because of the change in government. I am sure during this new Indian government, the war is bound to happen. Either China or Pakistan or both of them will attack India for sure.
Well... the Sino-Indian conflict occurred more than 50 years ago, and the tensions seems to have cooled down. I hate to say this, but actually it was the incompetence of the Indian rulers at that time (esp. Jawaharlal Nehru), which cost India some 40,000 sq.kms of Aksai Chin. He foolishly trusted the Chinese, and refused to strengthen the border posts along the Johnson Line.
