Qing dynasty [SEP] Territorial administration
In the early 20th century, Britain sent an expedition force to Tibet and forced Tibetans to sign a treaty. The Qing court responded by asserting Chinese sovereignty over Tibet, resulting in the 1906 Anglo-Chinese Convention signed between Britain and China. The British agreed not to annex Tibetan territory or to interfere in the administration of Tibet, while China engaged not to permit any other foreign state to interfere with the territory or internal administration of Tibet. Furthermore, similar to Xinjiang which was converted into a province earlier, the Qing government also turned Manchuria into three provinces in the early 20th century, officially known as the "Three Northeast Provinces", and established the post of Viceroy of the Three Northeast Provinces to oversee these provinces, making the total number of regional viceroys to nine.
