evidence: Soon after the Chinese occupied western Tibet in the early 1950s, they started claiming Barahoti as theirs. The IB recommended to the Government of India that it was essential that Delhi "should make it clear to the Government of Tibet and its Dzongpon that the Hoti Plain is Indian territory and the Tibetans have no right to establish any customs post there; nor can they exercise any authority in the area." [...] Though Barahoti was well inside India’s frontiers (clearly south of Tunjun-la, the watershed), arguments about the new ‘dispute’ continued with the exchange of hundreds of notes during the following months …and years. [...] Mehta explained that India made it clear that Barahoti was a small pasture ground south of Tunjun-la: "during the talks we specified the relevant coordinates and pointed out that the area involved was 2 miles in length and ¾ of a mile in breadth. The Chinese did not agree to our suggestion for the complete neutralisation of this area and hinted that they would continue to send civil officials, where upon we also informed them that we were reserving the right to send our own revenue officials to this area."
