Karachi Agreement

The Karachi Agreement of 1949 was signed by the military representatives of India and Pakistan, supervised by the United Nations Commission for India and Pakistan, establishing a cease-fire line in Kashmir following the Indo-Pakistani War of 1947. It established a cease-fire line which has been monitored by United Nations observers from the United Nations since then.
Background.
The Security Council Resolution 39 of April 1948 established a UN Commission (United Nations Commission for India and Pakistan — UNCIP) to mediate between India and Pakistan in order to bring about a cessation of fighting in Kashmir and to make arrangements for a popular plebiscite. After negotiations with the two sides, the Commission passed a three-part resolution in August 1948 and subsequently added a 'supplement'. The three parts dealt with ceasefire, terms for truce, and procedures for negotiation regarding the plebiscite. Both the countries accepted the resolution and a ceasefire was achieved on 31 December 1948.
Agreement.
The Karachi Agreement, formally called the "Agreement Between Military Representatives of India and Pakistan Regarding the Establishment of a Cease-Fire Line in the State of Jammu and Kashmir," was signed on 27 July 1949, supervised by the Truce Subcommittee of the UNCIP.
The signatories were:
The other members of the Indian delegation were Maj. Gen. K. S. Thimayya, Brig. Sam Maneckshaw, Maj. S. K. Sinha (who acted as the "aide-de-camp" for Gen. Srinagesh), and the secretaries of the Defence Ministry and the Ministry of Kashmir Affairs. The Pakistani delegation included Maj. Gen. Nazir Ahmed and Brig. Sher Khan and civil servants M. Ayub and A. A. Khan. The military representatives of the two sides negotiated for a week starting 18 July to demarcate the positions under their control.
S. K. Sinha stated that the Prime Minister Jawaharlal Nehru briefed the Indian delegation before the Karachi meeting, wherein he informed them that the UN Resolution conceded the legality of Kashmir's accession to India and, so, any "no man's land" would belong to India. The Pakistani delegation would need to produce proof to the UN Commission of factual positions of their control for all the territory they claim. Sinha stated that, based on this principle, the agreement demarcated several hundred square miles of territory on the Indian side even though there were no Indian troops in that territory.
The 830 kilometre long ceasefire line established in the agreement started from a southernmost point just west of the Chenab river in Jammu. It ran in a rough arc northwards and then northeastwards to the map coordinate NJ9842, about 19 km north of the Shyok river.
From the map point NJ9842 it was said to run due north to the international boundary with China, at a distance of about 60–65 km. Since there were no troops in that area of inaccessible glacial terrain, no effort was made to extend the ceasefire line between NJ9842 and the China border. This area, of the Siachen Glacier, eventually became a bone of contention between India and Pakistan.
Another anomaly arose at the southern end of the ceasefire line in Jammu. From the terminus of the ceasefire line to the international boundary between Indian and Pakistani Punjab, there was a gap of over 200 km, which was covered by a recognised "provincial boundary" between Pakistani Punjab and the princely state of Jammu and Kashmir. India generally referred to this boundary as the "international border", whereas Pakistan referred to it as the "border" or the "working border".

The Karachi Agreement between India and Pakistan established a cease-fire line to be supervised by the military observers. These observers, under the command of the Military Advisor, formed the nucleus of the United Nations Military Observer Group in India and Pakistan (UNMOGIP). On 30 March 1951, following the termination of the United Nations Commission for India and Pakistan (UNCIP), the Security Council, by Resolution 91 (1951) decided that UNMOGIP should continue to supervise the cease-fire line in Kashmir. UNMOGIP's functions were to observe and report, investigate complaints of cease-fire violations and submit its findings to each party and to the Secretary General.
