Brunei Darussalam

Brunei Darussalam, (pronounced /bruːˈnaɪ/ in English) officially the State of Brunei, Abode of Peace (Malay: Negara Brunei Darussalam, Jawi: بروني دارالسلام), is a country located on the north coast of the island of Borneo, in Southeast Asia. Apart from its coastline with the South China Sea it is completely surrounded by the state of Sarawak, Malaysia, and in fact it is separated into two parts by Limbang, which is part of Sarawak. This is odd in the fact that it is a separated country inside a separated country (the two parts of Malaysia).
Brunei, the remnant of a very powerful sultanate, regained its independence from the United Kingdom on 1 January 1984 and is a member of the Commonwealth of Nations.
