A potential China-India-Pakistan tripoint at Karakoram Pass is referenced in a 1963 boundary treaty between China and Pakistan concerning the Trans-Karakoram Tract, but India was not party to that treaty nor any tripoint agreement. The entire Siachen Glacier, with all major passes and heights of the Saltoro Ridge (including Sia La, Bilafond La, Gyong La, Yarma La (6,100m), and Chulung La (5,800m).), has been under the administration of India (currently as part of the union territory of Ladakh) since 1984. The current de facto tripoint is about 100 km west of the pass near Indira Col in the Siachen Muztagh, where the Actual Ground Position Line between Indian and Pakistani forces meets the border with China.
