East Asia Summit

The East Asia Summit (EAS) is an annual leaders-led forum launched in Kuala Lumpur in December 2005, designed as a strategic dialogue on political, security, and economic issues facing the Indo-Pacific region. It is convened by ASEAN, which sits at the institutional core, and meetings are held alongside the annual ASEAN Summit under the chairmanship of the rotating ASEAN chair.

Membership began with 16 states: the ten ASEAN members (Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand, Vietnam) plus Australia, China, India, Japan, New Zealand, and South Korea. The United States and Russia joined in 2011, bringing the total to 18 participating states. Timor-Leste was admitted to ASEAN in principle in 2022, which will eventually expand EAS membership as well.

Unlike the ASEAN Regional Forum (ARF), which is a broader security dialogue, the EAS is explicitly a leaders' summit and covers a wider thematic span. Priority cooperation areas identified over successive summits include environment and energy, education, finance, global health and pandemics, disaster management, and ASEAN connectivity. The forum has also become a venue for discussing sensitive strategic issues — notably the South China Sea disputes, North Korea's nuclear program, and Myanmar's political crisis since the February 2021 coup.

The EAS operates by consensus and produces non-binding Chairman's Statements and thematic declarations rather than treaty instruments. Notable outputs include the 2011 Declaration of the East Asia Summit on the Principles for Mutually Beneficial Relations (the Bali Principles) and various statements on maritime cooperation and non-proliferation.

Critics note that the EAS lacks a permanent secretariat — administrative support is provided by the ASEAN Secretariat in Jakarta — and that consensus decision-making limits its ability to act on contentious issues. Supporters argue its value lies precisely in being the only regular forum where leaders of the US, China, Russia, India, and Japan sit at the same table under ASEAN's convening role, reinforcing the principle of ASEAN centrality in regional architecture.
