Asia Centre started in early 2017 its third three-year cycle of the Observatory for Southeast Asia. It is now time to dive into Southeast Asia’s challenges, whether related to domestic or foreign policies on the one hand, or traditional or non-traditional security issues on the other hand. To this end, the Observatory for Southeast Asia relies on a network of young local researchers, who work as closely as possible to the field ; its director Eric Frécon is for instance based in Singapore. Lastly, in addition to the notes and roundtables, the Observatory for Southeast Asia releases every other month a Newsletter aiming at summarising the news and current affairs, to present the latest publications and to introduce the latest leading personalities.
