Tha Ton
Tha Ton, also spelled Thaton, is a sub-district of Mae Ai District in the far north of Chiang Mai Province, Thailand. In 2014 it had a population of 19,902. The sub-district is on the Kok River near the border with Myanmar, about a three hour drive north of Chiang Mai. The central village of the subdistrict is Ban Tha Ton.
History
The river forms part of the border and consequently the village has changed hands numerous times in the turbulent history of the area with the latest change happening in the early-20th century when the border was moved 3.2 km upstream leaving the north bank, previously part of Burma, to Thailand. This part of Tha Ton, known in Thai as Ban Rom Thai, is inhabited by the Shan ethnic group. The area around Tha Ton is populated by various hill tribes including Yao, Lisu, Lahu, Karen, and Akha. Tha Ton is also home to Chinese nationalists forced to flee from their home-in-exile after the coup in Burma.Administration
