Brunei Darussalam shares a common border with Sarawak, an East Malaysian state, which divides the country into two: the Temburong District makes up the eastern part, while the western portion consists of the Brunei-Muara, Tutong and Belait Districts.
The 570-sq-km Brunei-Muara District, where the capital Bandar Seri Begawan is located, is the smallest but most important and populous of the four districts.
The 1,166-sq-km Tutong District, the third largest, is home to indigenous groups such as Tutong, Kedayan, Dusun and Iban.
The Belait District, the heart of the oil and gas industry, is situated roughly 100km from the capital. Hilly lowlands, swampy plains and alluvial valleys dominate the Brunei-Muara, Tutong and Belait districts in the larger western portion of the country.
Mountainous terrain abounds in the eastern district of Temburong, which has a land area of 1,288-sq-km.
