 Though there is no clear historical record of the development of the town, it is said to have developed as a result of the construction of the Samdrup Jongkhar-Tashigang national highway in the 1960s.In the past the Sharchops of Tashigang, Dundsan, Orong and Yangtse used to trade in a small Indian border town in Assam called Gudama (current day Daranga or Darranga Mela, better known as Mela Bazar).Today it is one of the most important trading towns for the eastern districts of Bhutan.
