[5] The 830 kilometre long ceasefire line established in the agreement started from a southernmost point just west of the Chenab river in Jammu.
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.
[7] U.N. document number S/1430/Add.2[8] (which is the second addendum to the 1949 Karachi Agreement) shows the Cease Fire Line (CFL) marked on the Map of the State of Jammu and Kashmir.
Title of this addendum reads: Map of the State of Jammu and Kashmir showing the Cease Fire Line as Agreed Upon in the Karachi Agreement, Ratified by the Governments of India and Pakistan on 29 and 30 July Respectively.
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.
