The ASEAN Summit is the regular meeting of the leaders of the Association of Southeast Asian Nations. The group was founded in 1967. It is a regional club for talking through trade, security, and the daily business of neighboring countries, not a parliament that can pass a law for the whole region.
ASEAN now has 11 members. The original and later members are Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand and Vietnam. Timor-Leste became the 11th member in late October 2025, at the 47th Summit in Kuala Lumpur.
The chair rotates among the members. The Philippines holds the chair for 2026. Myanmar, which would have come next in the usual order, did not take the chair because of the conflict there. Being chair means the host sets the year's calendar and welcomes the other leaders. It does not mean Manila runs ASEAN.
The country already hosted the 48th ASEAN Summit on May 6 to 8 in Lapu-Lapu City, Cebu, at the Mactan Expo, with President Ferdinand Marcos Jr. in the chair. The 49th Summit and related meetings are set for Nov. 16 to 18 in Metro Manila, with the Philippine International Convention Center in Pasay as the main venue. Some official remarks have also referred to related meetings on Nov. 15 to 17. The Palace holiday covers Nov. 16 to 18. Related forums listed for the same week include the ASEAN Maritime Forum on Nov. 17 and the Expanded ASEAN Maritime Forum on Nov. 18.
"Related summits" is the phrase to watch. The leaders of the 11 members are the core. Partner countries and organizations are often invited to separate meetings on the edges of the week. U.S. President Donald Trump is among the foreign leaders expected in Manila for this cycle. Guest lists can still shift. The Philippine government is the host, not the author of every bilateral photo.
For people who do not work in diplomacy, the practical meaning is simpler. For three days, a slice of Pasay becomes a secured meeting ground, Metro Manila gets a holiday, and a long list of official motorcades will move between hotels, the PICC, and the airport. The decisions taken inside the hall will be issued as statements. The traffic outside is what most of the city will actually feel.
