Chiang Rai (Thai: เชียงราย, pronounced [t͡ɕʰīa̯ŋ rāːj]; Northern Thai: เจียงฮาย, Northern Thai pronunciation: [t͡ɕīa̯ŋ hāːj]) is the northernmost major city in Thailand, with a population of about 200,000 people. It is located in Mueang Chiang Rai District, Chiang Rai Province. Chiang Rai was established as a capital city in the reign of King Mangrai, in 1262 CE.
The average elevation of the province is 580 metres (1,903 ft). The north of the province is part of the so-called Golden Triangle, where the borders of Thailand, Laos and Burma converge, an area which prior to the rise of agricultural production of coffee, pineapple, coconuts, and banana plantations, was unsafe because of drug smuggling across the borders. The Mekong River forms the boundary with Laos, the Mae Sai and Ruak River with Burma. Through the town of Chiang Rai itself, flows the "Mae Kok" Kok River and south of it the Lao River, a tributary of the Kok.
