Viet Nam
Vietnam, officially the Socialist Republic of Vietnam, is a country in Southeast Asia. Located at the eastern edge of mainland Southeast Asia, it covers 311,699 square kilometres. With a population of over 96 million, it is the world's fifteenth-most populous country. Vietnam borders China to the north, Laos and Cambodia to the west, and shares maritime borders with Thailand through the Gulf of Thailand, and the Philippines, Indonesia, and Malaysia through the South China Sea. Its capital is Hanoi and its largest city is Ho Chi Minh City. Vietnam was inhabited as early as the Paleolithic age. The first known Vietnamese nation during the first millennium BC centred on the Red River Delta, located in modern-day northern Vietnam. The Han dynasty annexed and put the Vietnamese under Chinese rule from 111 BC, until the first independent dynasty emerged in 939.
