The Kingdom of Thailand, covering an area of 514,000 square kilometres, lies in the heart of Southeast Asia, roughly equidistant between India and China. It shares borders with Myanmar to the west and north, Lao P.D.R. to the north and northeast, Cambodia to the east and Malaysia to the south. Thailand lies within the humid tropics and remains hot throughout the year. Average temperatures are about 29 oC , ranging in Bangkok from 35 oC in April to 17 oC in December. Ethnic Thais form the majority, though the area has historically been a migratory crossroads, and thus strains of Mon, Khmer, Burmese, Lao, Malay, Indian and most strongly, Chinese stock produce a degree of ethnic diversity.
Integration is such, however, that culturally and socially there is enormous unity.
The people of Thailand share a rich ethnic diversity consisting of Thai, Mon, Khmer, Laotian, Chinese, Malay, Persian and Indian descendants. As a result, it is not possible to speak of a typical Thai physique. The Thais are, on the whole, a group of people who believe that life should be enjoyed, but no one should infringe on others' rights. The Thais are tolerant and hospitable, and it is easy to get along with them. Good manners, common sense and a smile are necessities in Thailand.
