Prime Minister Lee Hsien Loong will attend the three-day Commonwealth Heads of Government Meeting (CHOGM), with leaders keen to discuss common pressing concerns like balancing economic growth and social inclusion.
The theme of this year's summit, which takes place every two years and begins today, is "Growth with Equity: Inclusive Development."
Mr Lee is expected to share on Singapore's challenges in building an inclusive society and highlight some of its key early successes, such as equal education for all to avoid the creation of a permanent underclass.
Leaders of the 53-member Commonwealth, a voluntary association of independent states that were mostly former territories of the British Empire, are also expected to speak about issues of global and regional concern and the developmental challenges that small countries face.
Members span several continents and include Australia, Canada, India, the Bahamas, and Zimbabwe.
