Vientiane in the context of "Belt and Road Initiative"

Laos, officially the Lao People's Democratic Republic (LPDR), is the only landlocked country in Southeast Asia. Located on the Indochinese Peninsula, it is bordered by Myanmar and China to the northwest, Vietnam to the east, Cambodia to the southeast, and Thailand to the west and southwest. Having a population of approximately 8 million, its capital and most populous city is Vientiane.

The country traces its historic and cultural identity to Lan Xang, a kingdom which existed from the 13th to 18th centuries. Through its location, the kingdom was a hub for overland trade. In 1707, Lan Xang split into three kingdoms: Luang Prabang, Vientiane, and Champasak. In 1893, these kingdoms were unified under French protection as part of French Indochina. Laos was under Japanese administration during World War II, gaining independence in 1945 before returning to French administration until achieving autonomy in 1949. The country regained full independence in 1953 as the Kingdom of Laos, with a constitutional monarchy under Sisavang Vong. A Civil War from 1959 to 1975 saw the communist Pathet Lao, supported by North Vietnam, China and the Soviet Union, oppose the Royal Lao Armed Forces, backed by the United States. The war ended with the establishment of the Lao People's Democratic Republic in 1975 that aligned with the Soviet Union until the latter's dissolution in 1991.

The Mon (Mon: ဂကူမန်listen; Thai Mon: ဂကူမည်; Burmese: မွန်လူမျိုး‌, pronounced [mʊ̀ɰ̃ lù mjó]; Thai: มอญ, pronounced [mɔ̄ːn] listen) are an ethnic group who inhabit Lower Myanmar's Mon State, Kayin State, Kayah State, Tanintharyi Region, Bago Region, the Irrawaddy Delta, and several areas in Thailand (mostly in Pathum Thani province, Phra Pradaeng and Nong Ya Plong). The native language is Mon, which belongs to the Monic branch of the Austroasiatic language family and shares a common origin with the Nyah Kur language, which is spoken by the people of the same name that live in Northeastern Thailand. A number of languages in Mainland Southeast Asia are influenced by the Mon language, which is also in turn influenced by those languages.

The Mon were one of the earliest to reside in Southeast Asia, and were responsible for the spread of Theravada Buddhism in Mainland Southeast Asia. The civilizations founded by the Mon were some of the earliest in Thailand as well as Myanmar and Laos. The Mon are regarded as a large exporter of Southeast Asian culture. Historically, many cities in Myanmar, Thailand, and Laos today, including Yangon, Pathum Thani, Lamphun, Lampang, and Vientiane were founded either by the Mon people or Mon rulers.

The Laotian Civil War was waged between the Communist Pathet Lao and the Royal Lao Government from 23 May 1959 to 2 December 1975. The Kingdom of Laos was a covert theater during the Vietnam War with both sides receiving heavy external support in a proxy war between the global Cold War superpowers. The fighting also involved the North Vietnamese, South Vietnamese, American and Thai armies, both directly and through irregular proxies. The war is known as the Secret War among the American CIA Special Activities Center, and Hmong and Mien veterans of the conflict.

The Franco–Lao Treaty of Amity and Association (signed 23 October 1953) transferred remaining French powers to the Royal Lao Government (except control of military affairs), establishing Laos as an independent member of the French Union. However, this government did not include representatives from the Lao Issara anti-colonial armed nationalist movement. The following years were marked by a rivalry between the neutralists under Prince Souvanna Phouma, the right wing under Prince Boun Oum of Champassak, and the left-wing Lao Patriotic Front under Prince Souphanouvong and half-Vietnamese future Prime Minister Kaysone Phomvihane. Several attempts were made to establish coalition governments, and a "tri-coalition" government was finally seated in Vientiane.
