About Brunei
Brunei, officially Brunei Darussalam, is a country in Southeast Asia, situated on the northern coast of the island of Borneo. Apart from its coastline on the South China Sea, it is completely surrounded by the Malaysian state of Sarawak, with its territory bifurcated by the Sarawak district of Limbang. Brunei is the only sovereign state entirely on Borneo; the remainder of the island is divided between its multi-landmass neighbours of Malaysia and Indonesia. As of 2025, the country had a population of 466,330, being the least populated country in Asia of whom approximately 64,409 resided in the capital and largest city of Bandar Seri Begawan. Its official language is Malay, and Sunni Islam is the state religion of the country, although other religions are nominally tolerated. The government of Brunei is an absolute monarchy ruled by the Sultan, and it implements a fusion of English common law and jurisprudence inspired by Islam, including sharia.

Travel guide
The Sultanate of Brunei is a small but, thanks to natural gas and petroleum resources, very rich country on the island of Borneo in Southeast Asia. Although Brunei is not on most travellers' radar, it is a country of tranquil mosques, pristine jungles, and friendly inhabitants. Its full name is Negara Brunei Darussalam, with Darussalam appropriately meaning "Abode of Peace".
