In the late 1800s, in order to facilitate trade between the Indian subcontinent and Tarim Basin, the British attempted to promote a caravan route via the Chang Chenmo Valley as an alternative to the difficult and tariffed Karakoram Pass. The Maharaja Ranbir Singh at the request of the British made improvements to the trails and facilities of the campsites in Chang Chenmo Valley. Unfortunately, in addition of being longer and higher elevation than the traditional route, this route also goes through the desolate desert of Aksai Chin. By 1890s, traders have mostly given up on this route. At the time, Chang Chenmo valley was also a popular hunting spot for British officers on leave.
