The People`s Liberation Army crossed the Jinsha River on October 6 or 7, 1950 and defeated the Tibetan army on October 19.   Instead of continuing the military campaign, China asked Tibet to send representatives to Beijing to negotiate an agreement. The Dalai Lama believes that the draft agreement was written by China, and Tibetan representatives were not allowed to propose changes. China did not allow Tibetan representatives to communicate with the Tibetan government in Lhasa. The Tibetan delegation was not allowed to sign by Lhasa, but eventually came under pressure from the Chinese to sign anyway using specially crafted seals for this purpose.  The head of the Tibetan delegation Ngapoi Ngawang Jigme said he had the power to sign an agreement.  The Tibetan delegation initially objected to the reference #1 to the «aggressive imperialist forces of Tibet», but then acknowledged that there might be forces they did not know. Points #2 and #3 were asked about the importance of «local government», although the importance of «national regional autonomy» was not discussed, as the Tibetan delegation felt that things would continue as before. The Delegation of Ngapois attempted to eliminate the guarantees of power for the Panchen Lama in points #5 and #6, but the Chinese delegation replied that the Panchen Lama and the Dalai Lama should be treated in the same way; Either they have guaranteed their power, or not. The Tibetans recognized the point. Fundamental differences over the #8, the dissolution of the Tibetan army, led to a promise to renegotiate the subject later.
The most controversial point was #15 with regard to the creation of a military and administrative committee, with the Tibetan delegation believing that it disagreed with the position #11 on the Tibetan local government, which is itself carrying out reforms. Most of the other points were accepted without comment or with minor translation adjustments. In order to avoid embarrassing problems for the Chinese delegation, agreements with the Tibetan delegation on issues such as the maintenance of the Tibetan army should then be concluded in separate and secret agreements.  Did you know that one of the signatories who participated in the birth of Nagaland is nothing less than the former governor of Odhisa, Dr. SC Jamir? The signing of the agreement on the seventeenth points was then challenged as invalid in the Tibetan community in exile, which accused Tibetan delegates of signing under duress and that the Chinese allegedly used false Tibetan government seals. The exiled community and its supporters continue to assert that Tibetan representatives were not allowed to propose changes and that the Chinese government did not allow Tibetan representatives to communicate with Lhasa.  As the only living signatory to the agreement, Mr. Jamir said that the NPC has always strived to create a favourable political environment in the region in order to clearly and unequivocally emphasize the basis of the Nagas` legitimate claims and protracted political aspirations before the Indian government.
