The Singapore Institute of International Affairs (SIIA) is a non-profit and independent think tank dedicated to the research, analysis and discussion of regional and international issues. Founded in 1962, the institute is Singapore’s oldest think tank. Through policy research and dialogue, we aim to bridge the gap between policymakers, private sector decision-makers and experts to shape public influence as well as impact policy and social responses.
The SIIA is a membership-based organisation and our individual members are admitted from among the most prominent figures in our society who have made a positive contribution to their sector and profession. Our corporate members include leading Singaporean and multinational companies with regional businesses. The SIIA is also a founding member of the ASEAN Institutes of Strategic and International Studies (ASEAN-ISIS), a regional alliance of think tanks and plays a key role in Track II diplomacy, supplementing official dialogue between governments.
Since 2012, the SIIA has been consistently ranked as one of the top think tanks in Southeast Asia and the Pacific, in the Global Go-To Think Tank Index done by the University of Pennsylvania. In 2017, the SIIA was ranked the no. 1 independent think tank in Asia and in the top 50 globally (excluding USA).
