Trans-Karakoram Tract, Disputed mountain valley in Xinjiang, China
Trans-Karakoram Tract is a disputed mountain valley in Xinjiang, China, stretching between the Kunlun Mountains and the Karakoram peaks. The territory covers over 5000 square kilometers of high-altitude terrain with glaciers, narrow valleys, and steep rock walls shaping the landscape.
Pakistan transferred control over this territory to China in 1963 through the Sino-Pakistan Agreement. India continues to claim the valley and does not recognize the arrangement.
The names of peaks and passes in this territory come from the languages of Balti and Ladakhi communities who once lived here. Some of the highest mountain crossings still carry these old names, which travelers can spot on route markers.
Access to this territory requires special permits from Chinese authorities. Entry points are controlled through Taxkorgan and Yecheng counties, with travelers needing to arrange all documents in advance.
Francis Younghusband mapped parts of this territory in 1889 as the first European and called it Oprang. Some areas within the tract remain largely unexplored today and appear only roughly sketched on modern maps.
