evidence: Limbang is a small town in northern-most part of Sarawak. It is the capital of the division of the same name. [...] Limbang is geographically peculiar as it is sandwiched between two parts of Brunei. This situation was created in 1890 when the White Rajahs of Sarawak forced the Sultan of Brunei to cede the Limbang district. Till today, the Sultanate continues a not-much-heard-of territorial claim over Limbang. Because of the undeveloped interior of the district, most transportation links between Limbang and the rest of Sarawak have to go through Brunei. Limbang is the most culturally diverse and distinct part of Sarawak. It is a melting pot of many cultures, including Malay, Kedayan, Chinese, Iban and various Orang Ulu ethnic groups such as Lun Bawang, Bisaya, Murut, Kelabit and Penan. It has one of the highest concentration of Orang Ulu people in Sarawak.
