The Sultanate of Brunei (Full name: Negara Brunei Darussalam) is a small but - thanks to natural gas and petroleum resources - very rich country located in Southeast Asia. It is surrounded by Malaysia and has two parts physically separated by Malaysia, almost being an enclave. Strategically located on the South China Sea, close to vital sea lanes linking Indian and Pacific Oceans, it has an exclusive economic fishing zone that extends as far as Louisa Reef in the southern Spratly Islands although it makes no public territorial claim to the offshore reefs.
A constitutional sultanate, with a hereditary monarch, it is a modern example of how this form of government has stood the test of time.
