The 6th East Asia Summit in Bali marked two significant developments: 1) the enlargement of the EAS to include Russia and the US, expanding membership to 18 countries, and 2) the adoption of a declaration outlining principles for relations among EAS members. Going forward, the author argues the EAS will maintain its focus on strategic political and economic issues while strengthening implementation mechanisms. Priority areas of cooperation will continue across sectors such as finance, energy, education, health, and disaster management. Indonesia should seize the opportunity to promote Southeast Asian priorities within the EAS framework.
