Chiang Mai (Thai: เชียงใหม่[tɕʰiəŋ màj] ( listen), Northern Thai: ᨩ᩠ᨿᨦᩉ᩠ᨾᩲ᩵[tɕiəŋ màj]) sometimes written as "Chiengmai" or "Chiangmai", is the largest and most culturally significant city in northern Thailand. It is the capital of Chiang Mai Province, a former capital of the Kingdom of Lanna (1296–1768) and was the tributaryKingdom of Chiang Mai from 1774 until 1939. It is located 700 km (435 mi) north of Bangkok, among the highest mountains in the country. The city is along the Ping River, a major tributary of the Chao Phraya River. Chiang Mai means "new city" and was so-named because it was the new capital, founded in 1296, succeeding Chiang Rai (founded 1262) in the capital of the Lanna kingdom.
In recent years, Chiang Mai has become an increasingly modern city and has been attracting over 5 million visitors each year, of which between 1.4 million and 2 million are foreign tourists (depending on the year).
Chiang Mai gained prominence in the political sphere in May 2006, when the Chiang Mai Initiative was concluded here between the ASEAN nations and the "+3" countries (China, Japan, and South Korea). Chiang Mai was one of three Thai cities contending for Thailand's bid to host the World Expo 2020 (the others were Chon Buri and Ayutthaya). However, Ayutthaya was the city chosen by the Thai Parliament to register for the international competition.
