Brunei became independent in 1984 and, that same year, diplomatic relations were established with Brazil. Brazil does not have resident Embassy in the country; hence, bilateral relations are concurrently monitored by the Embassy of Brazil in Kuala Lumpur (Malaysia).
Brazil and MERCOSUR have intensified their relations with the Association of Southeast Asian Nations (ASEAN), of which Brunei is a member. In 2008, the 1st MERCOSUR-ASEAN Ministerial Meeting was held in Brasília, at which Brunei was represented by the Permanent Secretary of the Ministry of Foreign Affairs and Trade, Pehin Dato Lim Jock Hoi.
In 2013, the then Political Under-Secretary General for Asia and Oceania of the Ministry of Foreign Affairs, Ambassador Maria Edileuza Fontenele Reis, visited Brunei. On the occasion of the Rio+20 Conference, in June 2012, the Ministry of Energy of Brunei, Pehin Dato Yasmin Haji Umar, visited Brazil.
The volume of trade between the two countries is relatively low: in 2012, it registered a little more than USD 1 million. Trade opportunities were identified in the areas of aeronautics and military material and there are possibilities for investments of Brunei in Brazil in the fields of oil and sports facilities.
