Introduction

On May 7-8, 2026, the 48th ASEAN Summit centered on reaffirming the 11-member bloc’s role in addressing traditional and non-traditional security issues and further strengthening ASEAN’s regional resilience (ASEAN, 2026, para.1). Throughout these discussions, the bloc continued operating through the ASEAN Way of consensus and non-interference. Held in Cebu, Philippines, here are the four developments that stood out as key results of the said summit in anticipation of the 49th ASEAN Summit in November 2026.

1. Responding to the Middle East Crisis

ASEAN Member States (AMS) had expressed strong concerns over the attack made by Israel and the United States against Iran on February 28, 2026, and the retaliatory attacks from Iran on Gulf Cooperation Council (GCC) countries (ASEAN, 2026, para.182). AMS perceived this as a major threat to the safety of citizens and the peace and stability of the region and the world. To counter this problem, ASEAN issued the ASEAN Leaders' Statement on the Response to the Middle East (ASEAN, 2026, para.183).

The crisis has threatened Southeast Asia’s energy, food security, and public well-being. Consequently, ASEAN urged all countries to respect international law and the United Nations Charter to protect civilians and resolve conflicts peacefully. Apart from this, the leaders also reiterated ASEAN's balanced support for the right of Palestinians' self-determination and a two-state solution in line with international law (ASEAN, 2026, para.183-184).

2. Push for Code of Conduct (COC) in the South China Sea

AMS agreed to maintain restraint to avoid worsening of tensions in the South China Sea. The leaders affirmed peaceful resolution in accordance with international laws, notably the 1982 UN Convention on the Law of the Sea (UNCLOS) (ASEAN, 2026, para. 174). 

In terms of maritime trade, AMS adopted the Declaration on Maritime Cooperation of the ASEAN Leaders. The leaders also took note of Cambodia's ratification of UNCLOS in February 2026. Additionally, they welcomed plans to set up an ASEAN Maritime Centre in the Philippines (ASEAN, 2026, para.31).

3. A Decade of “One ASEAN, One Response” in Disaster Management

To mark the 10th anniversary of the “One ASEAN, One Response” declaration, leaders have embarked on efforts to transform the disaster response system in the face of frequent and challenging calamities. The adoption of the ASEAN Strategic Protocol for Emergency and Comprehensive Transformation Framework (ASPECT) has been welcomed by them (ASEAN, 2026, para.21). This was aimed at improving how the ASEAN’s response to emergencies with the help of better coordination and information sharing. It is expected that this would facilitate logistics and reduce customs and immigration procedures. This framework will complement the ASEAN Agreement on Disaster Management and Emergency Response (AADMER), and the 2026–2030 Work Programme (ASEAN, 2026, paras. 22, 130).

4. Youth Empowerment in Climate Action and Disaster Resilience

With nearly half of the total 700 million population of ASEAN comprising youths less than 30 years old, the leaders have declared the ‘ASEAN Declaration on the Empowerment of Youth in Climate Action and Disaster Resilience’ (ASEAN, 2026, para.87). Through this declaration, AMS commit themselves to ensuring that youth will be an integral part of climate action and disaster resilience initiatives. The leaders consider this imperative for the development of youth leadership in policymaking, capacity building, and community-based resilience-building programs (ASEAN, 2026, para.91).

5. Cebu Protocol and the Admission of Timor-Leste as the 11th Member

AMS have signed the Cebu Protocol, which is an amendment to the ASEAN Charter adopted in 2007. This was done to officially induct Timor-Leste as the 11th member of the organisation. The flag and emblem of ASEAN are due to be unveiled at the 49th ASEAN Summit following the completion of processes in all member countries (ASEAN, 2026, para.142).
