Excellent perspectives from Mr. Chavda. Folks like PKN need to be made aware of Chinese arguments.
Chinese do not bring in Marxian mumbo-jumbo to butress their claims, they do so on the basis of Chinese history. Sovreign India is the legal inheritor of British India and it is legal for Indian Govt to abide by all British agreements. China does not accept British treaties on Tibet and has deployed force or threatened to do so.
Tibet is the fountainhead of most of water flowing into India. China are fast acquiring capability to dam and alter the water flow pattern. Reestoring the rights of Tibet to be atleast autonomous is a great Indian imperative.
