PRIME MINISTER’S OFFICESINGAPORE13 July 2026

His Majesty Sultan Haji Hassanal Bolkiah Mu’izzaddin Waddaulah ibniAl-Marhum Sultan Haji Omar ‘Ali Saifuddien Sa’adul Khairi WaddienSultan and Yang Di-Pertuan of Brunei DarussalamPrime Minister, Minister of Defence, and Minister of FinanceBrunei Darussalam

On behalf of the people of Singapore, I extend my warmest congratulations on Your Majesty’s 80thbirthday.

Under Your Majesty’s wise and far-sighted leadership, Brunei has enjoyed decades of peace, stability, and progress. Your Majesty’s enlightened vision for Brunei’s modernisation and development has uplifted the lives of generations of Bruneians.

Your Majesty has also played a pivotal role in fostering a special and enduring relationship between our two nations. It is a relationship that can be traced back to the friendship and camaraderie between the late Seri Begawan and Mr Lee Kuan Yew, and that has grown with the personal bonds that Your Majesty has forged with each and every Singapore Prime Minister.

I have had the privilege of interacting with Your Majesty on several occasions from early in the years when I was in politics and government, and personally witnessed how Singapore and Brunei have maintained a steady, mutually respectful and deepening relationship under your leadership.

Singapore is grateful for Your Majesty’s steadfast support for our bilateral ties, which has brought our partnership to new heights and will benefit generations to come.

My wife Jane and I wish Your Majesty and Her Majesty Duli Raja Isteri continued good health, and many more years of bliss, and happiness. We look forward to welcoming Your Majesties to Singapore again soon.

His Majesty Sultan Haji Hassanal Bolkiah Mu’izzaddin Waddaulah ibniAl-Marhum Sultan Haji Omar ‘Ali Saifuddien Sa’adul Khairi WaddienSultan and Yang Di-Pertuan of Brunei DarussalamPrime Minister, Minister of Defence, and Minister of FinanceBrunei Darussalam

My heartiest congratulations to Your Majesty on the joyous occasion of Your Majesty’s 80thbirthday. As a mark of respect to Your Majesty on this special occasion, Senior Minister Lee Hsien Loong and Minister of State for Home Affairs and Social and Family Development Goh Pei Ming will attend Your Majesty’s birthday celebrations on behalf of the Singapore Government.

Since Brunei’s independence in 1984, Your Majesty has adroitly steered the country through exceptional challenges in a rapidly changing world. Like Singapore, Brunei is a small country that must stand on its own feet and remain open to the rest of the world. That Bruneians from all walks of life enjoy peace, harmony, and prosperity today is truly a testament to Your Majesty’s distinguished stewardship.

With Your Majesty’s unwavering support over the years, the special relationship that our two countries share has withstood the test of time. Our strong bilateral defence and monetary cooperation have been a cornerstone of our robust relationship. I am glad that we are commemorating the 50thanniversary of defence ties in 2026 and the 60thanniversary of the Currency Interchangeability Agreement in 2027. I am confident that our collaboration, based on mutual trust and respect, will strengthen further in the years ahead and bring forth even more opportunities for our peoples’ development and well-being.

My wife and I send Your Majesty and Her Majesty Duli Raja Isteri our best wishes for the continued good health and happiness of Your Majesties.

His Majesty Sultan Haji Hassanal Bolkiah Mu’izzaddin Waddaulah ibniAl-Marhum Sultan Haji Omar ‘Ali Saifuddien Sa’adul Khairi WaddienSultan and Yang Di-Pertuan of Brunei DarussalamPrime Minister, Minister of Defence, and Minister of FinanceBrunei Darussalam

Please accept my heartfelt congratulations on the momentous occasion of Your Majesty’s 80thbirthday. This is a historic milestone and it is only fitting that all Bruneians come together to honour the Sultan whom they deeply love and respect.

My father cherished his ties with the Seri Begawan. Together, they laid the foundations for the special and trusted friendship between our two nations. It has been my distinct privilege to partner Your Majesty in continuing that endeavour, and I am heartened that the next generation of leaders on both sides fully appreciate the significance of our important relationship and are committed to growing it into the future.

Ho Ching and I wish Your Majesty and Her Majesty Duli Raja Isteri good health and much happiness. We are honoured to attend Your Majesty’s birthday celebrations in Brunei and look forward to celebrating the joyous occasion with Your Majesties.

His Majesty Sultan Haji Hassanal Bolkiah Mu’izzaddin Waddaulah ibniAl-Marhum Sultan Haji Omar ‘Ali Saifuddien Sa’adul Khairi WaddienSultan and Yang Di-Pertuan of Brunei DarussalamPrime Minister, Minister of Defence, and Minister of FinanceBrunei Darussalam

Please accept my best wishes on the auspicious occasion of Your Majesty’s 80thbirthday. You are now an esteemed octogenarian!

It was my privilege and good fortune to have worked closely with Your Majesty to enhance our bilateral ties. Our countries remain firm friends today. In the years ahead, I am confident that Singapore and Brunei will continue to seek new pathways of cooperation for the betterment of our people.

My wife, Choo Leng, joins me in wishing Your Majesty and Her Majesty Duli Raja Isteri the very best of health and happiness.
