Aksai Chin
Aksai Chin is a region administered by China as part of Hotan County, Hotan Prefecture, Xinjiang and Rutog County, Ngari Prefecture, Tibet. It is claimed by India to be a part of its Leh District, Ladakh Union Territory. It is a part of the eastern portion of the Kashmir region and has been a subject of dispute between India and China since the late 1950s. Name. Aksai Chin () is first mentioned by Muhammad Amin, the Yarkandi guide of the Schlagintweit brothers. Amin's Aksai Chin was not a well-defined region, stretching indefinitely east into Tibet, south of  the Kunlun Mountains. Some sources interpret "Aksai" to be a word of Uyghur origin with the meaning "white stone desert", including several British colonial, modern Western, Chinese, and Indian sources. Some modern sources interpret it to mean "white brook" instead. At least one source interprets "Aksai" to mean "eastern" in the Yarkandi Uyghur dialect. The meaning regarding the word "Chin" is disputed. It is taken to mean "China" by some Chinese, Western, and Indian sources. At least one source takes it to mean "pass". Other sources omit "Chin" in their interpretations. History. Because of its elevation, the desolation of Aksai  Chin meant that it had no human importance other than as an ancient trade route, which provided a temporary pass during summer for caravans of yaks between Xinjiang and Tibet. For military campaigns, the region held great importance, as it was on the only route from the Tarim Basin to Tibet that was passable all year round. The Dzungar Khanate used this route to enter Tibet in 1717. One of the earliest treaties regarding the boundaries in the western sector was signed in 1842. Ladakh was conquered a few years earlier by the armies of Raja Gulab Singh (Dogra) under  the suzerainty of the Sikh Empire. Following an unsuccessful campaign into Tibet in 1840, Gulab Singh and the Tibetans signed a treaty, agreeing to stick to the "old, established frontiers", which were left unspecified. The British defeat of the Sikhs in 1846 resulted in the transfer of the Jammu and Kashmir region including Ladakh to the British, who then installed Gulab Singh as the Maharaja under their suzerainty. British commissioners contacted Chinese officials to negotiate the border, who did not show any interest. The British boundary commissioners fixed the southern end of the boundary at Pangong Lake, but regarded the  area north of it as "terra incognita". The Johnson Line. William Johnson, a civil servant with the Survey of India proposed the "Johnson Line" in 1865, which put Aksai Chin in Kashmir. This was the time of the Dungan revolt, when China did not control most of Xinjiang, so this line was never presented to the Chinese. Johnson presented this line to the Maharaja of Kashmir, who then claimed the 18,000 square kilometres contained within, and by some accounts territory further north as far as the Sanju Pass in the Kun Lun Mountains. The Maharajah of Kashmir constructed a fort  at Shahidulla (modern-day Xaidulla), and had troops stationed there for some years to protect caravans. Eventually, most sources placed Shahidulla and the upper Karakash River firmly within the territory of Xinjiang (see accompanying map). According to Francis Younghusband, who explored the region in the late 1880s, there was only an abandoned fort and not one inhabited house at Shahidulla when he was there – it was just a convenient staging post and a convenient headquarters for the nomadic Kirghiz. The abandoned fort had apparently been built a few years earlier by the Kashmiris. In 1878 the Chinese had reconquered Xinjiang , and by 1890 they already had Shahidulla before the issue was decided. By 1892, China had erected boundary markers at Karakoram Pass. In 1897 a British military officer, Sir John Ardagh, proposed a boundary line along the crest of the Kun Lun Mountains north of the Yarkand River. At the time Britain was concerned at the danger of Russian expansion as China weakened, and Ardagh argued that his line was more defensible. The Ardagh line was effectively a modification of the Johnson line, and became known as the "Johnson-Ardagh Line". The Macartney–Macdonald Line. In 1893, Hung Ta-chen , a senior Chinese official at St. Petersburg, gave maps of the region to George Macartney, the British consul general at Kashgar, which coincided in broad details. In 1899, Britain proposed a revised boundary, initially suggested by Macartney and developed by the Governor General of India Lord Elgin. This boundary placed the Lingzi Tang plains, which are south of the Laktsang range, in India, and Aksai Chin proper, which is north of the Laktsang range, in China. This border, along the Karakoram Mountains, was proposed and supported by British officials for a number of reasons. The Karakoram Mountains formed a natural  boundary, which would set the British borders up to the Indus River watershed while leaving the Tarim River watershed in Chinese control, and Chinese control of this tract would present a further obstacle to Russian advance in Central Asia. The British presented this line, known as the Macartney–MacDonald Line, to the Chinese in 1899 in a note by Sir Claude MacDonald. The Qing government did not respond to the note. According to some commentators, China believed that this had been the accepted boundary. 1899 to 1947. Both the Johnson-Ardagh and the Macartney-MacDonald lines were used on British  maps of India. Until at least 1908, the British took the Macdonald line to be the boundary, but in 1911, the Xinhai Revolution resulted in the collapse of central power in China, and by the end of World War I, the British officially used the Johnson Line. However they took no steps to establish outposts or assert actual control on the ground. In 1927, the line was adjusted again as the government of British India abandoned the Johnson line in favor of a line along the Karakoram range further south. However, the maps were not updated and still showed the  Johnson Line. From 1917 to 1933, the "Postal Atlas of China", published by the Government of China in Peking had shown the boundary in Aksai Chin as per the Johnson line, which runs along the Kunlun mountains. The "Peking University Atlas", published in 1925, also put the Aksai Chin in India. When British officials learned of Soviet officials surveying the Aksai Chin for Sheng Shicai, warlord of Xinjiang in 1940–1941, they again advocated the Johnson Line. At this point the British had still made no attempts to establish outposts or control over the Aksai Chin, nor was the issue ever  discussed with the governments of China or Tibet, and the boundary remained undemarcated at India's independence. Since 1947. Upon independence in 1947, the government of India used the Johnson Line as the basis for its official boundary in the west, which included the Aksai Chin. From the Karakoram Pass (which is not under dispute), the Indian claim line extends northeast of the Karakoram Mountains through the salt flats of the Aksai Chin, to set a boundary at the Kunlun Mountains, and incorporating part of the Karakash River and Yarkand River watersheds. From there, it runs east along the Kunlun  Mountains, before turning southwest through the Aksai Chin salt flats, through the Karakoram Mountains, and then to Panggong Lake. On 1 July 1954 Prime Minister Jawaharlal Nehru wrote a memo directing that the maps of India be revised to show definite boundaries on all frontiers. Up to this point, the boundary in the Aksai Chin sector, based on the Johnson Line, had been described as "undemarcated." Despite this region being nearly uninhabitable and having no resources, it remains strategically important for China as it connects Tibet and Xinjiang. During the 1950s, the People's Republic of China built a 1,200  km (750 mi) road connecting Xinjiang and western Tibet, of which 179 km (112 mi) ran south of the Johnson Line through the Aksai Chin region claimed by India. Aksai Chin was easily accessible to the Chinese, but was more difficult for the Indians on the other side of the Karakorams to reach. The Indians did not learn of the existence of the road until 1957, which was confirmed when the road was shown in Chinese maps published in 1958. The construction of this highway was one of the triggers for the Sino-Indian War of 1962. The Indian position , as stated by Prime Minister Nehru, was that the Aksai Chin was "part of the Ladakh region of India for centuries" and that this northern border was a "firm and definite one which was not open to discussion with anybody". The Chinese minister Zhou Enlai argued that the western border had never been delimited, that the Macartney-MacDonald Line, which left the Aksai Chin within Chinese borders was the only line ever proposed to a Chinese government, and that the Aksai Chin was already under Chinese jurisdiction, and that negotiations should take into account the status quo. In June 2006 , satellite imagery on the Google Earth service revealed a 1:500 scale terrain model of eastern Aksai Chin and adjacent Tibet, built near the town of Huangyangtan, about southwest of Yinchuan, the capital of the autonomous region of Ningxia in China. A visual side-by-side comparison shows a very detailed duplication of Aksai Chin in the camp. The model was surrounded by a substantial facility, with rows of red-roofed buildings, scores of olive-coloured trucks and a large compound with elevated lookout posts and a large communications tower. Such terrain models are known to be used in military training  and simulation, although usually on a much smaller scale. Local authorities in Ningxia claim that their model of Aksai Chin is part of a tank training ground, built in 1998 or 1999. In August 2017, Indian and Chinese forces near Pangong Tso threw rocks at each other. On September 11, 2019, People's Liberation Army troops confronted Indian troops on the northern bank of Pangong Lake. A continued face-off in the 2020 China–India skirmishes of May and June 2020 between Indian and Chinese troops near Pangong Tso Lake culminated in a violent clash on 16 June 2020, with  at least 20 deaths from the Indian side and no official reported deaths from the Chinese side. In 2021, Chinese state media reported 4 Chinese deaths. Both sides claim provocation from the other. Geography. Aksai Chin is one of the two large disputed border areas between India and China. India claims Aksai Chin as the easternmost part of the union territory of Ladakh. China claims that Aksai Chin is part of the Xinjiang Uyghur Autonomous Region and Tibet Autonomous Region. The line that separates Indian-administered areas of Ladakh from Aksai Chin is known as the Line of Actual Control  (LAC) and is concurrent with the Chinese Aksai Chin claim line. Aksai Chin covers an area of approximately . The area is largely a vast high-altitude desert with a low point (on the "Karakash River") at about above sea level. In the southwest, mountains up to extending southeast from the Depsang Plains form the "de facto" border (Line of Actual Control) between Aksai Chin and Indian-controlled Kashmir. In the north, the Kunlun Range separates Aksai Chin from the Tarim Basin, where the rest of Hotan County is situated. According to a recent detailed Chinese map, no roads cross the  Kunlun Range within Hotan Prefecture, and only one track does so, over the Hindutash Pass. Aksai Chin area has number of endorheic basins with many salt or soda lakes. The major salt lakes are Surigh Yilganing Kol, Tso Tang, Aksai Chin Lake, Hongshan Lake, etc. Much of the northern part of Aksai Chin is referred to as the Soda Plains, located near Aksai Chin's largest river, the Karakash, which receives meltwater from a number of glaciers, crosses the Kunlun farther northwest, in Pishan County and enters the Tarim Basin, where it serves as one of the main sources of  water for Karakax and Hotan Counties. The western part of Aksai Chin region is drained by the Tarim River. The eastern part of the region contains several small endorheic basins. The largest of them is that of the Aksai Chin Lake, which is fed by the river of the same name. The region as a whole receives little precipitation as the Himalayas and the Karakoram block the rains from the Indian monsoon. The nearby Trans-Karakoram Tract is also the subject of ongoing dispute between China and India in the Kashmir dispute. Demographics and economics. Prior to the 1940s, the  inhabitants of Aksai Chin were, for the most part, the occasional explorers, hunters, and nomads from India who passed through the area. Prior to European exploration in the 1860s, there were some jade mining operations on the Xinjiang side of Aksai Chin. They were abandoned by the time European explorers reached the area. In the 1860s to 1870s, in order to facilitate trade between the Indian subcontinent and Tarim Basin, the British attempted to promote a caravan route via the western side of Aksai Chin as an alternative to the difficult and tariffed Karakoram Pass. The route, referred to as  the Chang Chenmo line after the starting point in Chang Chenmo River valley, was discussed in the House of Commons in 1874. Unfortunately, in addition of being longer and higher elevation than Karakoram Pass, it also goes through the desolate desert of Aksai Chin. By 1890s, traders had mostly given up on this route. In the 1950s, India collected salt from various lakes in Aksai Chin to study the economic feasibility of salt mining operations in the area. By the end of the 1950s, in addition to having constructed a road, numerous PLA Ground Force outposts were constructed in a  few locations, including at Tianwendian, Kongka Pass, Heweitan and Tianshuihai. The road was later upgraded to the China National Highway 219. In the modern day, there are a few businesses along the highway serving motorists. In the 2010s, geological surveys were conducted in the Western Kunlun region, which Aksai Chin is part of. Huoshaoyun, a major lead-zinc deposit, and numerous smaller deposits were discovered in the region. Huoshaoyun is a mountain located in Aksai Chin near the Tibetan border. The mining development for Huoshaoyun started in 2017. Transportation. China National Highway 219 runs through Aksai Chin connecting Lhatse County  (Lhazê, Lazi) and Xinjiang in the Tibet Autonomous Region.
