Commanding the second-highest GDP per capita of all ASEAN nations, at $40,979 in 2014, Brunei Darussalam remains one of the most advanced economies in the South-east Asian region. This is in large part due to the Sultanate’s well-developed energy sector; however, with oil and gas prices falling substantially from mid-2014, new efforts are being made to increase the efficiency of production and diversify the economy to ensure future stability and sustainability.
