Months after the Simla agreement, China established border markings south of the McMahon Line. T. O`Callaghan, an official from the eastern sector of the northeastern border, moved all these markers to a location just south of the McMahon Line, then visited Rima to confirm with Tibetan officials that there was no Chinese influence in the area.  At first, the Indian government rejected the Simla agreement as incompatible with the 1907 Anglo-Russian agreement, which stipulated that neither party should negotiate with Tibet “except on the Chinese government.”  The British and Russians repealed the 1907 agreement in 1921, with mutual agreement.  It was not until the late 1930s that the British began using the McMahon line on official maps of the area. Thag La`s occupation operation was flawed as Nehru`s instructions were not clear and, for this reason, began very slowly.   In addition, each man had to carry 35 kilograms during the long hike, which greatly slowed the reaction.  When the Indian battalion reached the point of conflict, Chinese units controlled both sides of the Namka Chu River.  On 20 September, Chinese troops threw grenades at Indian troops and a shootout developed, triggering a long series of skirmishes for the rest of September.   Following the war, the Indian government commissioned an investigation that led to Henderson Brooks-Bhagat`s classified report on the causes of the war and the reasons for the failure. India`s performance in the 1962 altitude combat led to a review of the Indian army in terms of teaching, training, organization and equipment.
Neville Maxwell claimed that India`s role in international affairs was greatly diminished after the border war, even after the war, and that India`s position in the non-aligned movement suffered.  For decades, the Indian government has tried to keep the Hendersen-Brooks-Bhagat report secret, although some of them were recently disclosed by Neville Maxwell.  750,000 $US by the agreement managed by the CDC`s Center for Prevention and Response In 1911, the Xinhai Revolution led to power changes in China, and at the end of World War I, the British officially used the Johnson Line. They did not take steps to establish outposts or maintain on-site control.  According to Neville Maxwell, the British had used up to 11 different borders in the region because their demands had changed with the political situation.  From 1917 to 1933, the Chinese government`s “Postal Atlas of China” in Beijing had drawn the Aksai Chin border along the Johnson Line that runs along the Kunlun Mountains.   The Peking University Atlas, published in 1925, also brought the Aksai Chin to India.  After independence in 1947, the Indian government used the Johnson Line as the base for its official western border, Aksai Chin.  On 1 July 1954, Jawaharlal Nehru, India`s first prime minister, definitively declared the Indian position and affirmed that Aksai Chin was part of the Indian region of Ladakh for centuries and that the border (as defined by the Johnson Line) was not negotiable.
