Trans-Karakoram Tracts is a territory of India
The Trans-Karakoram Tract is an area of approximately 5,300 km² that was transferred by a border agreement from the Pakistani-administered Northern Areas to China in 1963 with the proviso that the settlement was subject to the final solution of the Kashmir dispute. Pakistan says that it was a no-man's undemarcated border land, hence no question arises of its being transferred. It is claimed by India as part of the state of Jammu and Kashmir. [...] The Tract is one of the most inhospitable areas of the world, with some of the highest mountains including Broad Peak, Gasherbrum and Masherbrum, and is adjacent to the highest battlefield in the world at Siachen Glacier.
