Khamber Jong, also called Gamba, Kampa, or Khampa Dzong, is a Tibetan hamlet north of Sikkim. In June 1903, Colonel Francis Younghusband, serving as British commissioner to Tibet, led a diplomatic mission consisting of five officers and five hundred troops through Nathu La to Khamber Jong. The objective of the mission was to meet Chinese and Tibetan representatives and discuss mutual non-aggression and trade agreements.
