evidence: The crossing of the Shipki La Pass by the Chinese Army Personnel without visaed Passports violates the Sino-Indian Agreement of April 29, 1954, in which the Shipki La Pass has been recognised as the border between India and Tibet region of China at that place. The Government of India presume that the Chinese Army Personnel crossed into Indian territory by mistake and not deliberately. [...] Traders and pilgrims of both countries may travel by the following passes and route:The intrusions meant that for China, passes such as Shipki La were not border passes, but located within China’s territory. Beijing’s interpretation of Article IV was: ‘the passes are only an indication of the route through which traders could enter India". [...] The Indian Government reminded the Chinese of the Panchsheel Agreement: "Shipki La is clearly the border and is acknowledged as such in the Sino-Indian Agreement of 29th April 1954, the Government of India consider any crossing of this border pass by armed personnel as aggression which they will resist."
