Prince Abdul Mateen’s appointment as Brunei’s foreign minister is among the most significant decisions in Sultan Hassanal Bolkiah’s latest cabinet reshuffle, which he announced on June 4.

Mateen, who has never held a formal cabinet portfolio before, takes charge of a ministry that was once synonymous with his uncle, Prince Mohamed Bolkiah. Following Brunei’s independence in 1984, Prince Mohamed became the country’s first minister of foreign affairs and trade, and remained one of the kingdom’s most influential figures for more than three decades before being dropped from the cabinet in October 2015.

In the age of social media, Mateen has emerged as the most recognizable member of the Brunei royal family, with more than 3 million followers on Instagram. Despite his parents’ divorce, he followed in his father’s footsteps by pursuing a military career. He attended the Royal Military Academy Sandhurst in the United Kingdom in 2010 and was commissioned into the Royal Brunei Air Force after graduation. He was later transferred to the Royal Brunei Armed Forces, where he currently serves as a Lieutenant Colonel.

Like his father, Mateen is an avid polo player. A supporter of English Premier League club Arsenal, he also owns a football team in Brunei known as AM Gunners. Once widely described by international media as Asia’s most eligible bachelor, Mateen ended his bachelorhood when he married his longtime fiancée, Yang Mulia Anisha Rosnah, in January 2024. Their lavish 10-day wedding celebration in Bandar Seri Begawan attracted global attention and reinforced his growing public profile.

After removing Prince Mohamed from the foreign ministry portfolio in 2015, Sultan Hassanal Bolkiah personally assumed the position. His recent decision to hand the ministry to Mateen, rather than another senior royal or career diplomat, is widely seen as a sign of the Sultan’s confidence in his son and his readiness to entrust him with one of the country’s most important portfolios.

The other royal newcomer to the cabinet is Prince Abdul Malik, who joins the cabinet for the first time as minister in the Prime Minister’s Office. Crown Prince Al-Muhtadee Billah, meanwhile, has retained his position as senior minister at the Prime Minister’s Office.

Taken together, the appointments carry a broader political message. The exclusion of Prince Mohamed and the elevation of three of the Sultan’s sons suggest that key positions of state are increasingly being concentrated within the Sultan’s direct line of succession rather than among his siblings. While Al-Muhtadee Billah remains the undisputed heir apparent, Malik and Mateen are now being given valuable experience in government, reinforcing perceptions that the next generation of the Bolkiah dynasty is being prepared to take on greater responsibilities

Another notable feature of the reshuffle is the creation of three coordinating ministers, a move that has drawn comparisons with Singapore’s governance model. Brunei has close ties with Singapore as the Brunei dollar and the Singapore dollar are pegged at a 1:1 par value under the two nations’ longstanding Currency Interchangeability Agreement.

In Singapore, coordinating ministers oversee policy areas that cut across multiple ministries and help ensure better coordination across government agencies.  These appointments reflect a similar emphasis on policy integration as the country enters a crucial final decade in implementing Wawasan Brunei 2035. Launched in 2007, this long-term national development plan aims to transform the country into a globally recognized nation led by a skilled workforce, a high quality of life, and a highly diversified, sustainable economy by the midpoint of the next decade.

The move also addresses a practical challenge. Achieving the goals of Wawasan 2035 requires close cooperation among the ministries responsible for the economy, education, manpower, investment, digitalization, infrastructure, and social development. Although Brunei has long advocated a “whole-of-government” approach, implementation has often been fragmented across agencies. The new coordinating ministers appear to be intended to bridge these gaps and accelerate decision-making.

The reshuffle also marks a milestone for women in government. The inclusion of four female ministers represents the highest number since Brunei’s independence, signaling a gradual expansion of women’s representation at the highest levels of government.
