Despite its remote location and relatively small size, Mae Sot (แม่สอด) is among the most culturally diverse cities in Thailand. Walking down the town's streets you’ll see a fascinating ethnic mixture of Burmese men in their longyi (sarongs), Hmong and Karen women in traditional hill-tribe dress, bearded Muslims, Thai army rangers and foreign NGO workers. Burmese and Karen are spoken as much as Thai, shop signs along the streets are in Thai, Burmese and Chinese, and much of the temple architecture is Burmese. Mae Sot has also become the most important jade and gem centre along the border, with much of the trade controlled by Chinese and Muslim immigrants from Myanmar.
