At the 7th Ho Rih Hwa Leadership in Asia Public Lecture organised by SMU, Prime Minister Mr Lee Hsien Loong argued that Singapore’s key challenge will change with time. Over a 10-year horizon, it will be the economy; in 25 years, demography; and in 50 years, identity. PM Lee said that ultimately, Singapore’s ability to confront these challenges would depend not only on policies or circumstances, but responsible and committed leaders who can win the support of the people and rally the country together.
