In recent years, his attention has increasingly turned towards social cohesion. Concerned by racial division, religious intolerance and polarising rhetoric, he began working through Dialog Rakyat for National Cohesion and Unity to revisit the spirit of the Rukun Negara.
From dialogues held between 2016 and 2019 emerged the Harmoni-Mesra framework – a practical approach centred on respect, trust, understanding, ethical conduct and opportunities for Malaysians of different backgrounds to interact meaningfully.
The Harmoni-Mesra Campus Programme, launched with UCSI University in 2022, seeks to bring these principles into university communities and nurture a new generation that values dialogue over division.
It is a fitting continuation of his earlier work. Whether building scientific institutions or strengthening community relationships, Tan Sri Omar has consistently focused on systems that outlast individuals.
His contributions have earned honorary doctorates from universities in Malaysia and abroad, alongside recognitions including the ASEAN Achievement Award in Science, the Tun Abdul Razak Award, Tokoh Akademik Negara and the KSI National Unity Leadership Award.
But at 94, he appears less interested in looking back at what he has accomplished than in asking what he can still contribute.
Tan Sri Omar’s journey reflects the spirit of the Merdeka Award Trust through sustained service, knowledge applied with purpose and leadership directed towards strengthening the nation for generations to come.
