In July 1972, India and Pakistan signed an agreement establishing a line of control in Kashmir, which, with slight differences, followed the same course as the ceasefire line established in 1949 by the Karachi Agreement. India considered that unMOGIP`s mandate had expired, as it specifically concerned the ceasefire line under the Karachi Agreement. However, Pakistan did not accept this position. From the point of the NJ9842 map, it must pass north of the international border with China, at a distance of about 60 to 65 km. Since there were no troops in this area of inaccessible glacial sites, no effort was made to extend the ceasefire line between the NJ9842 and the Chinese border. This area, the Siachen Glacier, eventually became a bone of contention between India and Pakistan.  C. The ceasefire line described above is drawn on a one-inch map (if available) and then checked by local commanders on either side, with the help of UN military observers, to eliminate no man`s land. If local commanders are unable to reach an agreement, the matter is referred to the Commission`s military adviser, whose decision is final. After this verification, when a ceasefire came into effect on 17 December 1971, a number of positions on both sides of the 1949 ceasefire line had changed ownership. The Security Council met on 12 December and adopted Resolution 307 (1971) on 21 December, calling for a permanent ceasefire to be in effect in all conflict zones until all armed forces have withdrawn from their territory and in positions that fully respect the Jammu-and-Kashmir ceasefire line. , as monitored by MINMOGIP.
The first team of unarmed military observers, which eventually formed the nucleus of the United Nations military observer group in India and Pakistan (UNMOGIP), arrived in the mission area in January 1949 to oversee the ceasefire between India and Pakistan in Jammu and Kashmir and to support the UNCIP military adviser. The observers` missions, defined by the military adviser, consisted of accompanying local authorities in their investigations, gathering as much information as possible and making it as complete, accurate and impartial as possible.
