In 1904, the British Empire launched an expedition to Tibet to counter perceived Russian influence in the region. The expedition, which initially set out with the stated goal of resolving border disputes between Tibet and Sikkim, quickly turned into an invasion of Tibet. The forces of the expedition invaded and captured Lhasa, with the 13th Dalai Lama fleeing to the countryside. After the British captured Lhasa, a treaty was signed between the two nations, known as the Convention Between Great Britain and Tibet, which gained for the British great economic influence in the region while ensuring that Tibet remained under Chinese control. Just two years later, however, the British signed a new treaty with the Qing government, known as the Convention Between Great Britain and China Respecting Tibet, which affirmed Chinese control of Tibet. The British agreed not to annex or interfere in Tibet in return for indemnity from the Chinese government, while China engaged "not to permit any other foreign state to interfere with the territory or internal administration of Tibet".
