Vietnam

Vietnam, officially the Socialist Republic of Vietnam (SRV), is a country at the eastern edge of Mainland Southeast Asia. With an area of about 331,000 square kilometres (128,000 sq mi) and a population of over 100 million, it is the world's 15th-most populous country. One of two communist states in Southeast Asia, Vietnam is bordered by China to the north, Laos and Cambodia to the west, the Gulf of Thailand to the southwest, and the South China Sea to the east; it also shares maritime borders with Thailand, Malaysia, and Indonesia to the south and southwest, the Philippines to the east, and China to the northeast. Its capital is Hanoi, while its largest city is Ho Chi Minh City.

Vietnam was inhabited by the Paleolithic age, with states established in the first millennium BC on the Red River Delta in modern-day northern Vietnam. The Han dynasty annexed northern and central Vietnam, which were subsequently under Chinese rule from 111 BC until the first dynasty emerged in 939. Successive monarchical dynasties absorbed Chinese influences through Confucianism and Buddhism, and expanded southward to the Mekong Delta, conquering Champa. During most of the 17th and 18th centuries, Vietnam was effectively divided into two domains of Đàng Trong and Đàng Ngoài. The Nguyễn—the last imperial dynasty—surrendered to France in 1883. In 1887, its territory was integrated into French Indochina as three separate regions. In the immediate aftermath of World War II, the Viet Minh, a coalition front led by the communist revolutionary Ho Chi Minh, launched the August Revolution and declared Vietnam's independence from the Empire of Japan in 1945.

Vietnam went through prolonged warfare in the 20th century. After World War II, France returned to reclaim colonial power in the First Indochina War, from which Vietnam emerged victorious in 1954. As a result of the treaties signed between the Viet Minh and France, Vietnam was also separated into two parts. The Vietnam War began shortly after, between the communist North Vietnam, supported by the Soviet Union and China, and the anti-communist South Vietnam, supported by the United States. Upon the North Vietnamese victory in 1975, Vietnam reunified as a unitary communist state that self-designated as a socialist state under the Communist Party of Vietnam (CPV) in 1976. An ineffective planned economy, a trade embargo by the West, and wars with Cambodia and China crippled the country further. In 1986, the CPV launched economic and political reforms similar to the Chinese economic reform, transforming the country to a socialist-oriented market economy. The reforms facilitated Vietnamese reintegration into the global economy and politics.

Vietnam is a developing country with a lower-middle-income economy. It has high levels of corruption, censorship, environmental issues and a poor human rights record. It is part of international and intergovernmental institutions including the ASEAN, the APEC, the Non-Aligned Movement, the OIF, and the WTO. It has assumed a seat on the United Nations Security Council twice.

The name Việt Nam (pronounced [viə̂tˀ nāːm], chữ Hán: 越南), literally "Viet South", means per Vietnamese word order "Viet of the South"; meanwhile, per Classical Chinese word order, "Việt Nam" ambiguously means either "South of the Viet" or "Viet people's Southern country".

A variation of the name, Nanyue (or Nam Việt, 南越), was first documented in the 2nd century BC. The term "Việt" (Yue) (Chinese: 越; pinyin: Yuè; Cantonese Yale: Yuht; Wade–Giles: Yüeh⁴; Vietnamese: Việt) in Early Middle Chinese was first written using the logograph "戉" for an axe (a homophone), in oracle bone and bronze inscriptions of the late Shang dynasty (c. 1200 BC), and later as "越". At that time, it referred to a people or chieftain to the northwest of the Shang. In the early 8th century BC, a tribe on the middle Yangtze were called the Yangyue, a term later used for peoples further south.

Between the 7th and 4th centuries BC, 'Yue'/'Việt' referred to the State of Yue in the lower Yangtze basin and its people. From the 3rd century BC, the term was used for the non-Chinese populations of southern China and northern Vietnam, with particular ethnic groups called Minyue, Ouyue, Luoyue (Vietnamese: Lạc Việt), etc., collectively called the Baiyue (Bách Việt, Chinese: 百越; pinyin: Bǎiyuè; Cantonese Yale: Baak Yuet; Vietnamese: Bách Việt; lit. 'Hundred Yue/Viet').

The term 'Baiyue'/'Bách Việt' first appeared in the book Lüshi Chunqiu compiled around 239 BC. By the 17th and 18th centuries AD, educated Vietnamese apparently referred to themselves as người Việt (Viet people) or người Nam (southern people).
