Science before diplomacy

Erywan Yusof’s route into diplomacy began with scientific training. He completed an honours degree in genetics and biophysics at Leeds in 1988 and an MSc in Genetics and Its Applications at University College Swansea in 1991. His civil-service career began as a veterinary chemist in 1989.

Within the Ministry of Industry and Primary Resources, he later headed the Miscellaneous Crop Unit. From 1994, his responsibilities included ASEAN agricultural matters and coordination for regional agriculture and forestry ministers’ meetings. These technical and administrative duties preceded the trade negotiations and ministerial appointments for which he later became better known.

Economic diplomacy and senior administration

A transfer to the foreign ministry’s Department of International Trade in 2005 brought Erywan into economic diplomacy. He participated in the Brunei–Japan Economic Partnership Agreement negotiations and led Brunei’s negotiating work on the ASEAN–Australia–New Zealand Free Trade Agreement. The negotiating period should not be mistaken for the agreement’s later signing date.

He became deputy permanent secretary in January 2008 and permanent secretary later that year. That progression connected regional technical coordination with senior foreign-ministry administration. Swansea subsequently awarded him an honorary Doctor of Letters in December 2018, a separate recognition from his earlier earned science qualifications.

The second-minister office

Erywan became Deputy Minister of Foreign Affairs and Trade on 22 October 2015 and Minister of Foreign Affairs and Trade II on 30 January 2018. Later in 2018, the title became Minister of Foreign Affairs II. The change in portfolio wording was not the beginning of his ministerial service.

Brunei’s cabinet appointments effective 4 June 2026 retained him as Second Minister of Foreign Affairs. The same announcement appointed Prince ‘Abdul Mateen as Minister of Foreign Affairs. These are separate offices: Erywan’s title does not make him the sole head of the ministry, and older references to the Sultan’s concurrent foreign portfolio are not descriptions of the new cabinet.

The Myanmar assignment and its limits

On 4 August 2021, Erywan was appointed Special Envoy of the ASEAN Chair on Myanmar following the military coup and ASEAN’s Five-Point Consensus. His mandate concerned dialogue and humanitarian access. It was separate from the United Nations envoy’s office, even though the UN welcomed his appointment.

International partners supported his intention to meet all parties. The planned October mission was cancelled after access to Aung San Suu Kyi and other parties was not granted. His appointment did not give him control over Myanmar’s authorities or guarantee access. Cambodia’s ASEAN chairmanship brought a different envoy, Prak Sokhonn, in 2022.
