Bolikhamsai (also Borikhamxay, Lao ບໍລິຄໍາໄຊ) is a province of Laos, located in the middle of the country. Pakxanh, Thaphabath, Pakkading, Borikhan, Viengthong and Khamkheu are its districts and Paksan is its capital city. The province is also home to Nam Theun 2 Dam, the country's largest hydroelectric project.
Bolikhamsai Province, one of the provinces of Laos, covers an area of 14,863 square kilometres (5,739 sq mi). Bolikhansai Province borders Xiangkhouang Province to the northwest, Vietnam to the east, Khammouan Province to the south, and Thailand to the west. The province includes the Annamite Range, stretching east to Vietnam, while to the west are the Mekong River and Thailand. At 3,700 square kilometres (1,400 sq mi), the Nakai–Nam Theun National Biodiversity Conservation Area in Bolikhamsai and Khammouane Provinces is the third largest protected area in Laos.
The province faced many invasions from the Siamese throughout its history. The foundation of Paksan dates from the late nineteenth century. In 1836, the Siamese assumed suzerainty over Laos. After 1865, the invasions of "Hos", Chinese gangs from southern China, affected the provinces of Xieng Khouang and Bolikhamsai (Borikhane). In 1876, the King of Siam, Rama V, ordered the creation of the Muong Borikhane with the last survivors of the Ho invasion of 1874. The Muong of Borikhane was placed under the authority of Kha Luang Nong Khai.
In the 1890s, Christian missionaries of the Missions étrangères de Paris arrived on the Mekong River, a few miles from the mouth of the Nam Sane. They built a church at Paksan. By 1911, the Muong Borikhane had about 61 villages housing a population of about 4000 inhabitants. Paksane had grown to several thousand in 1937. On 14 April 1958, the soldiers of Muong Kao Post (Borikham district) under the command of sergeant May arrested Thao Am of Ban Boky.
The modern province was formed in 1986 from parts of the Vientiane Province and Khammuan. In recent times, religious tension has been apparent in the province, and local authorities have evicted Christian communities from numerous villages. In February 2005, 100 villagers were forced to sell their possessions and prepare to be evicted in Kok Poh village in Borikham district.  As a result, numerous churches have been destroyed and rebuilt in the province, reflecting the tension.
Bolikhamsai Province covers an area of 14,863 square kilometres (5,739 sq mi). Bolikhamsai Province borders Xiangkhouang Province to the northwest, Vietnam to the east, Khammouan Province to the south, and Thailand to the west. Notable settlements include Pakse (Muang Pakxam), Borikham, Lak Sao, Muang Bo, Ban Hatkham, Ban Thana, Ban Thasi, Ban Hai, Ban Don, Ban Soppanga, Ban Pak Ham, Ban Naxon, Ban Kengbit, Ban Pakha, Ban Phayat, Ban Sopchat, Ban Muangcham and Ban Nap. The province includes the Annamite Range, stretching east to Vietnam, while to the west are the Mekong River and Thailand.
Bolikhamsai Province has a very rugged terrain, with large bolders and streams. The altitude ranges from 140–1,588 metres (460–5,210 ft). The principal river is the Nam Kading, meaning "Water like a bell", a tributary of the Mekong River; its catchment covers about 92% of the provincial area. The other main rivers are the Nam Muan, Nam Sat, and the Nam Tek. Waterfalls of note include the Tad Leuk, Tad Xay and Tad Xang. The longest mountain range in the province is the Phou Louang range, running to the southwest, the Phou Ao range to the southeast; the Thalabat range to the northwest, and the Pa Guang range to the northeast. In Khamkheuth district, there is picturesque karst limestone scenery, which is allegedly the largest formation of its type in Southeast Asia. The many rock pinnacles have formed stone forest similar to limestone outcrops in southern China.
At 3,700 square kilometres (1,400 sq mi), the Nakai–Nam Theun National Biodiversity Conservation Area in Bolikhamsai and Khammouane Provinces is the third largest protected area in Laos. It comprises mixed semi-tropical forests (reported in large areas of Indochina. The wetlands of the Nam Kading National Protected Area and the Phou Khao Khouay National Protected Area attract numerous migratory birds, and also has some 13 globally and 12 regionally endangered mammals such as the Asiatic black bear, clouded leopard, elephant, giant muntjac, gaur, sun bear, and tiger and both northern and southern white-cheeked crested gibbon. The Saola (spindle horn) or Vii Quang Ox (Pseudoryx nghetinhensis) was discovered in neighbouring Vietnam in 1992 and sighted since then in this conservation area. In 1996, the Saola was discovered in the adjoining Khammouane Province, in a living condition.
Under the WWF Greater Mekong Lao PDR Country Programme studies have been carried out in the two forest areas in the province to assess the degree of sustainable Rattan harvest and production as its provides significant income in whole of the Mekong region to rural villages. The forest areas covered are 349ha of forest area in Ban Soupphouan (Nong Kan and Phu Sangnoy villages) and 364ha in Phonthong. The species sampled were Mak Naeng (cardamom), Bamboo shoots of many species, All year San (Lao lady palm), mushrooms, Pak van, Kha (Galangal), Wai Houn (D.jenkinsiana rattan species), Phak kout (Vegetable fern), Wai khom (C.viminalis rattan species), Ya houa and Ka don nam.
Mammals include tiger, Malayan sun bear, guar, giant muntjac, Malayan sun bear, elephant, clouded leopard, and Asiatic black bear. The mammal species protected under the Nam Kading National Protected Area are four Critically Endangered and Endangered primate species of the Northern White-cheeked Gibbon, the Southern White-cheeked Gibbon, Red-shanked Douc Langur and two Leaf-monkey species. Bird species recorded in the province are Bulbuls (Pycnonotidae), Bare-faced Bulbul (Pycnonotus hualon), Thrushes (Turdidae) and Green Cochoa (Cochoa viridis). Four species of hornbills are also reported.
The province is made up of the following districts:
Laos's largest hydroelectric project, Nam Theun 2 Dam (NT2), began operation in March 2010. The scheme diverts water from the Nam Theun, a tributary of the Mekong River, to the Xe Bang Fai River, enabling a generation capacity of 1,070 MW, from a 350 m (1,148 ft) difference in elevation between the reservoir and the power station. At the time of signing in 2005, NT2 was the largest foreign investment in Laos, the world's largest private sector cross-border power project financing, the largest private sector hydroelectric project financing, and one of the largest internationally financed IPP projects in Southeast Asia. The dam also marked a return by the World Bank to funding large-scale infrastructure, after a decade-long hiatus. The dam also exports energy to neighboring Thailand, thus is important to the regional economy. Along with Khammouane and Savannakhet provinces, it is one of the main tobacco producing areas of Laos, and also one of the main producers of sugar cane and oranges.
Wat Phabath and Wat Phonsanh temples are important pilgrimage centres located between Vientiane and Pakxan. Wat Phabath is said to have a very large “footprint” of Lord Buddha and numerous murals. The location provides vistas of the Mekong River. Lak Sao, on the border, has the Nampao Checkpoint, crossing into Vietnam.
