China to be part of Xinjiang, contains an important road link that connects the Chinese regions of Tibet and Xinjiang. China’s construction of this road was one of the triggers of the conflict. Arunachal Pradesh (called South Tibet by China) is also claimed by both nations — although it is roughly the size of Austria.
hroughout most of the 19th century the expanding British and Russian empires were jockeying for influence in Central Asia, and Britain decided to hand over Aksai Chin to the Chinese administration as a buffer against a Russian invasion. The newly-created border was known as the MacCartney-MacDonald Line, and both British-controlled India and China now began to show Aksai Chin as Chinese. In 1911 the Xinhai Revolution resulted in power shifts in China, and by 1918 (in the wake of the Russian Bolshevik Revolution) the British no longer saw merit in China’s continuing possession of the region. On British maps, the border was redrawn as the original Johnson Line.
1954, India published new maps that included the Aksai Chin region within the boundaries of India (maps published at the time of India’s independence did not clearly indicate whether the region was in India or Tibet). When an Indian reconnaissance party discovered a completed Chinese road running through the Aksai Chin region of the Ladakh District of Jammu and Kashmir, border clashes and Indian protests became more frequent and serious. In January 1959, PRC premier Zhou Enlai wrote to Nehru, rejecting Nehru’s contention that the border was based on treaty and custom and pointing out that no government in China had accepted as legal the McMahon Line, which in the 1914 Simla Convention defined the eastern section of the border between India and Tibet. The Dalai Lama, spiritual and temporal head of the Tibetan people, sought sanctuary in Dharmsala, Himachal Pradesh, in March 1959, and thousands of Tibetan refugees settled in northwestern India, particularly in Himachal Pradesh. The People’s Republic of China accused India of expansionism and imperialism in Tibet and throughout the Himalayan region. China claimed 104,000 km² of territory over which India’s maps showed clear sovereignty, and demanded “rectification” of the entire border.
British India gained a common border with China after the British wrested control of Manipur and Assam from the Burmese, following the First Anglo-Burmese War of 1824–1826. In 1847, Major J. Jenkins, agent for the North East Frontier, reported that the Tawang was part of Tibet. In 1872, four monastic officials from Tibet arrived in Tawang and supervised a boundary settlement with Major R. Graham, NEFA official, which included the Tawang Tract as part of Tibet. Thus, in the last half of the 19th century, it was clear that the British treated the Tawang Tract as part of Tibet. This boundary was confirmed in a 1 June 1912 note from the British General Staff in India, stating that the “present boundary (demarcated) is south of Tawang, running westwards along the foothills from near Ugalguri to the southern Bhutanese border.
Kolkata, then known as Calcutta, was the capital of British India from 1772 to 1911. It was also geographically the easiest accessible metropolitan area from China by land. The first person of Chinese origin to arrive in Calcutta was Yang Tai Chow who arrived in 1778. He worked in a sugar mill with the eventual goal of saving enough to start a tea trade. Many of the earliest immigrants worked on the Khidderpore docks. A police report in 1788 mentions a sizeable Chinese population settled in the vicinity of Bow Bazaar Street.
The foreign secretary of the British Indian government, Henry McMahon, who had drawn up the proposal, decided to bypass the Chinese (although instructed not to by his superiors) and settle the border bilaterally by negotiating directly with Tibet. According to later Indian claims, this border was intended to run through the highest ridges of the Himalayas, as the areas south of the Himalayas were traditionally Indian. However, the McMahon Line lay south of the boundary India claims.
