The ideal thing is Sino-Indian Cooperation. But the problem is the past imperialistic designs of China. Its motives are suspect. It has taken Aksai-Chin, earlier claimed Sikkim, now claiming Arunachal Pradesh. Earlier overran Tibet with brutal force. Made incursions into India in 1962 when we lost several thousands of our soldiers. Claiming Formosa (Taiwan). Its motives, even good, are always suspect to us.
