The Convention of Calcutta

Calcutta, India.[3]
The Convention recognized a British protectorate over Sikkim and demarcated the Sikkim–Tibet border.

China is said to have negotiated the treaty without consulting Tibet, and the Tibetans refused to recognize it.[2] China's inability to deliver on the treaty eventually necessitated a British expedition to Tibet in 1904, setting in motion a long chain of developments in the history of Tibet. Modern international law jurists state that the convention exposed the Chinese 'impotence' in Tibet.[4]

The boundary established between Sikkim and Tibet in the treaty still survives today, as part of the

China–India border.[5] It has an impact on the modern day Doklam dispute between China, India and Bhutan.[6]

Background

The British imperative in North East India was to open the markets of Tibet and by extension China to their manufactured textiles, tobacco, grain, tools and tea.[7]

Provisions

Under Article 1, the boundary of Sikkim and Tibet was defined as the crest of the mountain range separating the waters flowing into the Teesta River in Sikkim and its tributaries from the waters flowing into the Tibetan Mochu River and northwards into other rivers of Tibet. The line commenced at Mount Gipmochi on the Bhutan frontier, and followed the above watershed to the point where it met Nepali territory.

Aftermath

A protocol was added to the original convention in December 1893. "Regulations Regarding Trade, Communications, and Pasturage to Be Appended to the Sikkim-Tibet Convention of 1890" allowed for the establishment of a British trading post in Old Yatung, Tibet as well as laid down regulations concerning pasturage and communication.[8][9]

The 1904 Convention of Lhasa states "The Government of Thibet engages to respect the Anglo-Chinese Convention of 1890 and to recognize the frontier between Sikkim and Thibet, as defined in Article I of the said Convention, and to erect boundary pillars accordingly."[2]
