The village of Santikhiri , formerly known as Mae Salong , is in the Thai highlands on Doi Mae Salong mountain of the Daen Lao Range, in Mae Fa Luang District, Chiang Rai Province, the northernmost province of Thailand. The area has an alpine-like landscape and climate, and is known for its hill tribe villages, tea plantations, and cherry blossoms.
Santikhiri's early history centered on the Golden Triangle's opium trade, in which its distinctive population – the "lost army" of the Republic of China Army's 93rd Division – became involved. At the conclusion of the Chinese Civil War in 1949, some remnants of the anti-communist Kuomintang (KMT) forces refused to surrender, including 278th Regiment of the 93rd Division and 709th Regiment of the 237th Division (led by General Li Kuo-hui). The troops fought their way out of Yunnan in south-western China, and its soldiers lived in Burma's (now Myanmar) jungles. The army grew and part of it returned to Taiwan under international pressure. The remaining troops were led by Gen Tuan Shi-wen (also known as Chiwan Khamlue) and sought asylum in Mae Salong later. In exchange for their asylum, they fought for Thailand until 1982, helping to counter the communist insurgency on the Thai frontier. In reward, the Thai government granted citizenship to most of the KMT soldiers and their families.
Cash crops, especially tea, have now replaced the growing of opium poppies, and Santikhiri today is a tourist attraction known as "Little Switzerland".
