a trade-market of Tibet, situated in the mouth of the Chumbi valley near the Indian frontier. According to the Convention of 1890-93, the market at Yatung was opened to India, and the conduct of the Tibetans in building a wall across the road between Yatung and Tibet was one of the incidents that led up to the British mission of 1904. According to the treaty of that year, a British trade-agent was to be maintained at Yatung.
