I don't have to lie. Political Boundary and Government? could you clarify 'Government' ? Is it necesary that the government, by which i presume you mean the State should be a King or something equivalant, that exercises sovergnity over a territory? Is that some kind of gold standard? Let me ask you something. Can't an order exist without a monarch(or group of feudals) impose it on the people within a territory. Rule of law isn't a modern invention, you know. However inefficient the Law may be, Rule of law has been internalised by the Indian society from times immemorial. Its unique about India. Order and civility(with it's imperfections ofcourse). That should qualify as Political boundary or Government(whatever you meant) and hence, you don't need an entity to exercise sovergnity over the territory to call it a nation.
But chinese way claiming things is absurd by any standard. You can't claim a territory because, at some point in history the territory came under a monarch controlling Middle kingdom(or the other way around). it's plain BS.
Chinese Trolls here acting strangly. I think, they think they understood what they read., can't really blame them.
