Wakhan Corridor
The Wakhan Corridor (, ) is a narrow strip of territory located within the Badakhshan province of Afghanistan. This corridor stretches eastward, connecting Afghanistan to Xinjiang, China. It also separates the Gorno-Badakhshan Autonomous Region of Tajikistan in the north from the northern Pakistan in the south. This high mountain valley serves as the source of both the Panj and Pamir rivers, which converge to form the larger Amu River. For countless centuries, a vital trade route has traversed this valley, facilitating the movement of travelers to and from East, South, and Central Asia. The corridor was formed after an 1893 agreement between Mortimer Durand of the British Raj and Emir Abdur Rahman Khan of Afghanistan, creating the Durand Line. This narrow strip acted as a buffer zone between the Russian Empire and the British Empire (the regions of Russian Turkestan, now in Tajikistan, and the northern part of British Raj, now in Pakistan). Its eastern end bordered China's Xinjiang region, then claimed by the Qing dynasty. The corridor is in the Wakhan District of Afghanistan's Badakhshan province. As of 2020, it had 17,167 residents. The northern part of the Wakhan, populated by the Wakhi and Pamiri people, is also referred to as the Pamir. The closest major airport for the residents to use is Fayzabad Airport in the city of Fayzabad to the west, which can be reached by a road network. Geography

At its western entrance, near the Afghan town of Ishkashim, the corridor is  wide. The western third of the corridor varies in width ()  and widens to  in the central Wakhan. At its eastern end, the corridor forks into two prongs that wrap around a salient of Chinese territory, forming the  boundary between the two countries. The Wakhjir Pass, which is the easternmost point on the southeastern prong, is about  from Ishkashim. The easternmost point of the northeastern prong is a nameless wilderness about  from Ishkashim. On the Chinese side of the border is the Tashkurgan Tajik Autonomous County of Xinjiang Uyghur Autonomous Region. The northern border of the corridor is formed by the Pamir River and Lake Zorkul in the west and the high peaks of the Pamir Mountains in the east. To the north is Tajikistan's Gorno-Badakhshan Autonomous region. To the south, the corridor is bounded by the high mountains of the Hindu Kush and Karakoram. Along the southern flank of the corridor, there are two mountain passes that connect the corridor to its neighbours. The Broghol pass offers access to the Khyber Pakhtunkhwa region of Pakistan, while the Irshad Pass connects the corridor to Gilgit-Baltistan. The Dilisang Pass, which also connects to Gilgit-Baltistan, is disused. The easternmost pass, as indicated above, is the Wakhjir Pass, which connects to China and is the only border connection between that country and Afghanistan. The corridor is higher in the east than in the west; (the Wakhjir Pass is  in elevation) and descends to about  at Ishkashim. The Wakhjir River emerges from an ice cave on the Afghan side of the Wakhjir Pass and flows west, joining the Bozai Darya near the village of Bozai Gumbaz to form the Wakhan River. The Wakhan River then joins the Pamir River near Kala-i-Panj to form the Panj River, which then flows out of the Wakhan Corridor at Ishkashim. The Chinese consider Chalachigu Valley, the valley east of Wakhjir Pass on the Chinese side connecting Taghdumbash Pamir, to be part of the Wakhan Corridor. The high mountain valley is about  long. This valley, through which the Tashkurgan River flows, is generally about  wide and less than  at its narrowest point. This entire valley on the Chinese side is closed to visitors; however, local residents and herders from the area are permitted access. History
Although the terrain is extremely rugged, the Corridor was historically used as a trading route between Badakhshan and Yarkand. It appears that Marco Polo came this way. The Portuguese Jesuit priest Bento de Goes crossed from the Wakhan to China between 1602 and 1606. In May 1906, Sir Aurel Stein explored the Wakhan and reported that at that time, 100 pony loads of goods crossed annually to China. There were further crossings in 1874 by Captain T.E. Gordon of the British Army, in 1891 by Francis Younghusband, and in 1894 by Lord Curzon. Early travellers used one of three routes:
 A northern route led up the valley of the Pamir River to Zorkul Lake, then east through the mountains to the valley of the Bartang River, then across the Sarikol Range to China. A southern route led up the valley of the Wakhan River to the Wakhjir Pass to China. This pass is closed for at least five months a year and is only open irregularly for the remainder. A central route branched off the southern route through the Little Pamir to the Murghab River valley. From a non-Afghan point of view, the corridor is in part a political creation from The Great Game between British India and Russian Empire. In the north, an agreement between the empires in 1873 effectively split the historic region of Wakhan by making the Panj and Pamir Rivers the border between Afghanistan and the then-Russian Empire. In the south, the Durand Line Agreement of 1893 marked the boundary between British India and Afghanistan. This left a narrow strip of land ruled by Afghanistan as a buffer between the two empires, which became known as the Wakhan Corridor in the 20th century. The corridor has been closed to regular traffic for over a century and there is no modern road. There is a rough road from Ishkashim to Sarhad-e Broghil built in the 1960s, but only rough paths beyond. These paths run some  from the road end to the Chinese border at Wakhjir Pass, and further to the far end of the Little Pamir. Jacob Townsend has speculated on the possibility of drug smuggling from Afghanistan to China via the Wakhan Corridor and Wakhjir Pass, but concluded that due to the difficulties of travel and border crossings, it would be minor compared to that conducted via Tajikistan's Gorno-Badakhshan Autonomous Province or through Pakistan, both having much more accessible routes into China. The remoteness of the region has meant that, despite the long-running wars of Afghanistan since the late 1970s, the region has remained virtually untouched by conflict, and many locals, mostly composed of ethnic Pamir and Kyrgyz, are not aware of the wars in the country. The Islamic Republic of Afghanistan asked the People's Republic of China on several occasions to open the border in the Wakhan Corridor for economic reasons or as an alternative supply route for fighting the Taliban insurgency. The Chinese resisted, largely due to unrest in its far western province of Xinjiang, which borders the corridor. , it was reported that the United States had asked China to open the corridor. In July, 2021, the area came under the Taliban control for the first time during the group's summer offensive. It was reported that hundreds of ethnic Kyrgyz nomads along with their livestock attempted to flee north into Tajikistan. It is patrolled by forces of the Islamic Emirate of Afghanistan, which took over responsibility from the previous NATO-trained Afghan National Security Forces. As of June 2023, there have been discussions between foreign ministers of China and Afghanistan to the opening of the strategically significant corridor to enhance the trade ties between Beijing and Kabul. Afghanistan's Foreign Minister Amir Khan Muttaqi and Chinese Foreign Minister Wang Yi both met on the sidelines in Tibet during the third Trans-Himalaya Forum for International Cooperation, to discuss the possibilities of improving trade ties.
