Brunei Darussalam, with a population of around 421,300 in 2017, is the smallest country in the ASEAN region, both in terms of area and population. The country is independent from energy import, due to its vast domestically available oil and gas reserves. Brunei Darussalam has the ninth largest Liquefied Natural Gas (LNG) reserve in the world as well as the fourth largest oil producer in South East Asia region. In 2017, the GDP of Brunei accounted is around 12.2 billion USD, of which 52.6% came from the oil and gas industry. This sector also accounts for more than 90% of the total national export. Hence the declination of oil prices and drop in fossil energy production causes Brunei’s GDP to decline over the past few years (-1.3% as of 2017). Bandar Seri Begawan is the city of the state. Malay is the official language, while english is widely spoken among the population.
