Rinchengang[1][2][a] (Tibetan: རིན་ཆེན་སྒང, Wylie: rin chen sgang, THL: rin chen gang, ZYPY: Rinqêngang)[9] or Renqinggang[10][11] (Chinese: 仁青岗村; pinyin: Rén qīng gǎng cūn) is a town in the Chumbi Valley and the headquarters of the Xia Yadong Township of Yadong County, Tibet region of China.

[15][16] The town has one of the largest tracts of flat land in the Chumbi valley covering around 580 sq km of grasslands and forests.

Archibald Campbell, the Deputy Commissioner of Darjeeling, wrote in 1848 that the people of all three countries, Sikkim, Bhutan and Tibet, traded here.

In December 1903 Laurence Waddell passed through Rinchengang on his way to Lhasa and described it as follows:[21] Craggy mountains rise on either side into jagged snow-streaked peaks banded by dark pines, and between, the clear green waters of the Mo river...

The meadow here is a quarter of a mile broad, and its turfy terraces, sprinkled with the frosted remains of last year’s wild-flowers... are dotted freely over with fine large houses, two- and three-storeyed in the Swiss chalet style, with widely-projecting eaves and wooden balconies carved and gaudily painted.

Being on the route from the Jelep La pass, it participated in the trade between Tibet and the Indian towns Kalimpong and Darjeeling as well as Sikkim's Gangtok.

[25] Ekai Kawaguchi, a Japanese Buddhist monk who travelled in Tibet, chronicled the usage of mules to transport wool from Tomo-Rinchen-gang to Kalenpong.

[8][better source needed] After the Younghusband Expedition (1903–1904), the British moved the trade mart to (new) Yatung and also opened the Nathu La pass for travel from Sikkim.

[28][29] Before the construction of Rinchengang as a market, according to a trader from Sikkim, Motilal Lakhotia,[30] "Richengang was just a small settlement with some houses and cultivated fields and something they would just pass by on their tedious journey.
