The Trans-Karakoram Tract is an area of nearly 5,180/ 5,800 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.
