The actual India-Pakistan boundary is divided into four types of borders: disputed Sir Creek (SC) riverine border, mutually agreed India–Pakistan International Border (IB) from north of Sir Creek to north of Dhalan near Jammu, LoC across disputed Kashmir and Ladakh regions from north of Dhalan in India and west of Chicken's Neck in Pakistan to Point NJ9842, and Actual Ground Position Line (AGPL) across Siachen from Point NJ9842 to Indira Col West. Siachen lies south of the Shaksgam ceded by Pakistan to China via the 1963 Sino-Pakistan Agreement but also claimed by India and Aksai Chin held by China since 1962 but also claimed by India. The Shaksgam Tract, controlled by China, is located north of the Saltoro mountain range from the Apsarasas Kangri Range to northwest of K2.R Baghela and M Nüsserab, 2015, Securing the heights: The vertical dimension of the Siachen conflict between India and Pakistan in the Eastern Karakoram, Political Geography (journal), Volume 48, Pages 24–36.
