[5] To attract both domestic and foreign investments, the BEDB develops policies, incentives, and strategies with a particular focus on advanced technology industries and specialised services that hold strong export potential.

Its responsibilities include encouraging foreign participation in priority industries, assisting with permits, clearances, public project tenders, and cost assessments, and assigning dedicated account managers to streamline the investment process.

However, with the establishment of the Ministry of Industry and Primary Resources (MIPR) and the Financial Institutional Division under the MoFE, some of the BEDB's responsibilities, such as tourism and insurance, were transferred to these entities.

[9] The Brunei Economic Development Board (Amendment) Order, 2001, effective from 1 June 2001,[10] restructured the agency, further solidifying its legislative framework for promoting domestic and foreign investments.

The board's primary role was to position Brunei as an attractive investment destination while fostering industries that could add value to hydrocarbons and support the development of non-oil and gas-related sectors.

[24] In 2004, the BEDB partnered with Halcrow Group on a US$1.7 billion deep-water port at Pulau Muara Besar (PMB), projected to save Brunei $43 million over two years while generating jobs.

[3] Aligned with Wawasan Brunei 2035, the BEDB partnered with the Ministry of Development and MIPR to promote e-business and ICT initiatives, fostering a knowledge-driven, paperless economy.

[28] The Sultan Haji Omar Ali Saifuddien Bridge, completed in 2019 for $1.6 billion, became Brunei's largest modernisation project, connecting the Brunei–Muara and Temburong districts, enhancing tourism, and unlocking new economic opportunities.

[30] Additionally, the BEDB partnered with Gulf News to release an eight-page report on 29 July 2024, highlighting FDI opportunities in Brunei's five priority sectors: downstream oil and gas, food, ICT, services, and tourism.
