Saharat Thai Doem was an administrative division of Thailand. It encompassed parts of the Shan States of British Burma annexed by the Thai government after the Japanese conquest of Burma.

Shan State is a state of Myanmar. Shan State borders China (Yunnan) to the north, Laos to the east, and Thailand to the south, and five administrative divisions of Myanmar in the west. The largest of the 14 administrative divisions by land area, Shan State covers 155,800 km2, almost a quarter of the total area of Myanmar. The state gets its name from Burmese name for the Tai peoples: "Shan people". The Tai (Shan) constitute the majority among several ethnic groups that inhabit the area. Shanland is largely rural, with only three cities of significant size: Lashio, Kengtung, and the capital, Taunggyi. Taunggyi is 150.7 km northeast of the nation's capital Naypyitaw.
