The SIIA features in a Straits Times article on think tanks in the region and in Singapore.
Professor Simon Tay, chairman of Singapore Institute of International Affairs, said the growing attention being paid to regional think-tanks is tied to the Obama administration's focus on this region.
'If you look at the American think-tanks - the Council of Foreign Relations, Carnegie Endowment, Brookings Institution - all have filled their gaps on South-east Asia,' he said.
The surveys reflect 'the perspective of the watcher'.
Indeed, US President Barack Obama is expected to travel to Indonesia sometime this year and Asean ministers may visit Washington to meet him.
Prof Tay noted that while South-east Asian think-tanks may not be known for their volume of output, they have been influential in shaping the views of regional governments and other policymakers.
