China–Tajikistan border


The China–Tajikistan border is in length and runs from the tripoint with Kyrgyzstan following a roughly north-south line across various mountain ridges and peaks of the Pamir range down to the tripoint with Afghanistan. The border divides Murghob District, Gorno-Badakhshan Autonomous Region in Tajikistan from Akto County, Kizilsu Kyrgyz Autonomous Prefecture and Taxkorgan Tajik Autonomous County, Kashgar Prefecture in Xinjiang Uygur Autonomous Region, China.

History

The origins of the border date from the mid-19th century, when the Russian empire expanded into Central Asia and established control over the Lake Zaysan region. The establishment of the border between the Russian Empire and the Qing Empire, not too different from today's Sino-Kazakh/Kyrgyz/Tajik border was provided for in the Convention of Peking of 1860; the actual border line pursuant to the convention was drawn by the Treaty of Tarbagatai and the Treaty of Uliassuhai, leaving Lake Zaysan on the Russian side. The Qing Empire's military presence in the Irtysh basin crumbled during the Dungan revolt. After the failure of the rebellion and the reconquest of Xinjiang by Zuo Zongtang, the border between the Russian and the Qing empires in the Ili River basin was further slightly readjusted, in Russia's favour, by the Treaty of Saint Petersburg and a series of later protocols. In 1915 an agreement was signed more precisely delimiting the border between the Ili Valley and the Dzungarian Alatau region.
The southern-most section of the frontier remained undemarcated, owing partly to the ongoing rivalry between Britain and Russia for dominance in Central Asia known as the Great Game; eventually the two agreed that Afghanistan would remain an independent buffer state between them, with Afghanistan’s Wakhan Corridor being created in 1895. China was not a party to these agreements and hence the southern-most section of the China-Russia boundary remained undefined. When Tajikistan became independent in 1991 it inherited a section of the China-USSR frontier. That boundary followed the drainage basin divide between the Amu Darya and the Yarkand River until reaching Markansu.
In 2011, Tajikistan ratified a 1999 deal to cede and respectively of land in the Pamir Mountains to the People's Republic of China, ending a 130-year dispute. In the treaty, China also relinquished claims to over of Tajikistani territory. The Republic of China had historically made similar claims in the area. Tajik attitudes toward the boundary treaty varied significantly among different interest groups, ranging from overt opposition to overt support.

Geography

A point north of the Markansu River on the China–Tajikistan border is the westernmost point of China.
The border's southern terminus is found at the Afghanistan-China-Tajikistan tripoint on Povalo-Shveikovskogo Peak / Kokrash Kol Peak which is also the eastern end of the Afghanistan-Tajikistan border and the northern end of the Afghanistan-China border as well as the easternmost point of Afghanistan.

Border crossings

The Karasu Port of Entry at the Kulma Pass is the only modern day border crossing between China and Tajikistan. Historically, two passes further south along the border, Nezatash Pass and Beyik Pass, have also been traversed. Northwest of Kulma Pass is the Uzbel/Kyzyl-Dzhiik Pass.
