[2] Much of the township's area comprises disputed territory: the township spans an area of 204.7 square kilometres (79.0 sq mi), excluding disputed territory,[3] and 650.88 square kilometres (251.31 sq mi) including it.The township straddles the disputed Bhutan-China border, near the sites of the 2017 China-India border standoff.The township's center is the village of Rinchengang, on the bank of the Amo Chu valley, which also receives the track from Sikkim's Jelep La pass.In addition to Rinchengang, the township also includes the Geling, Chema and Pipitang villages upstream along the Amo Chu, and Assam-Rotsa (or Asamthang) downstream.[4] In addition, the Township includes large territories in Bhutan that China claims.These claims however do not find historical support in the testimony of British Indian officials.
