evidence: Brunei, [lower-alpha 2] officially Brunei Darussalam, [lower-alpha 3] [lower-alpha 4] 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 2023 [update] , the country had a population of 455,858, [11] of whom approximately 180,000 resided in the capital and largest city of Bandar Seri Begawan. Its official language is Malay and Islam is the state religion of the country, although other religions are nominally tolerated. The government of Brunei is a constitutional absolute monarchy ruled by the Sultan, and it implements a fusion of English common law and jurisprudence inspired by Islam, including sharia. [...] Brunei is one of many nations to lay claim to some of the disputed Spratly Islands. [128] The status of Limbang as part of Sarawak has been disputed by Brunei since the area was first annexed in 1890. [128] The issue was reportedly settled in 2009, with Brunei agreeing to accept the border in exchange for Malaysia giving up claims to oil fields in Bruneian waters. [129] The Brunei government denies this and says that their claim on Limbang was never dropped. [130] [131]
