The meetings brought together senior defense officials from ASEAN member states and officials responsible for defense from the ADMM-Plus partner countries. Dato’ Astanah Abdul Aziz, ASEAN’s deputy secretary-general for the Political-Security Community, represented the ASEAN Secretariat, according to the ASEAN Secretariat.

What officials reviewed

The ASEAN Defence Senior Officials’ Meeting, or ADSOM, reviewed progress under the ASEAN Defence Ministers’ Meeting work program for 2023 through 2026. Officials also discussed newly proposed initiatives under the ADMM and external engagements by the defense sector.

In the separate ADSOM-Plus discussions, officials reviewed progress by the ADMM-Plus expert working groups and exchanged views on regional security issues and recent developments. The ASEAN statement described those discussions in broad regional terms and did not identify a specific new South China Sea measure.

Philippine officials stress ASEAN’s role

Philippine defense officials framed the meeting around preserving ASEAN solidarity, centrality and strategic autonomy as the regional security environment becomes more complex, according to Philippine News Agency reporting.

That language reflects the host government’s public framing, not a documented consensus on a new operational initiative. The videoconference brought senior officials together for coordination and preparation; the public record does not say that it created a joint force, operational command structure or new enforcement arrangement.

October meetings are the next checkpoint

ASEAN’s 2026 public notional calendar lists the 20th ASEAN Defence Ministers’ Meeting for October 28, 2026, in Metro Manila, Philippines. It lists the 13th ADMM-Plus for October 29.

Because the calendar is explicitly notional and was issued as of January 8, the dates should be treated as planned rather than irrevocably fixed. The August officials’ meetings discussed preparations for those ministerial sessions, which are the next scheduled opportunity for governments to announce concrete initiatives or additional political positions.

What the meeting did not decide

The public ASEAN account does not report a new maritime patrol, binding defense pact, South China Sea code-of-conduct result or other specific maritime mechanism. It also does not say that the territorial disputes were resolved or materially advanced.

A separate ASEAN-China working-group meeting on the South China Sea took place in Manila from August 19 through 21 to continue consultations on the Code of Conduct, according to China’s Foreign Ministry. That was a distinct diplomatic track from the August 26-27 defense officials’ meetings.

Why it matters

The immediate result of the ADSOM and ADSOM-Plus meetings was procedural and diplomatic: officials reviewed existing work, considered proposals, discussed regional developments and prepared the October agenda. That kind of institutional coordination can keep communication open among governments with different security interests, even when it does not produce a new operation or agreement.

For U.S. readers, the meetings signal that ASEAN and its dialogue partners continue to use formal channels to discuss regional security as South China Sea tensions and wider Indo-Pacific pressures persist. They do not, by themselves, change military commitments, navigation rules or the balance of forces. The clearest next test will be what governments publicly adopt or announce in Metro Manila in October.

The ASEAN Defence Senior Officials’ Meeting, known as ADSOM, and ADSOM-Plus are both scheduled for Aug. 10–14. The calendar also lists preparatory meetings for the ASEAN Ministerial Meeting on Transnational Crime, along with related consultations, across Aug. 10–15. The 20th ASEAN Ministerial Meeting on Transnational Crime is listed within that period.

The meetings bring ASEAN members and dialogue partners together on security and transnational crime as the region faces heightened maritime and geopolitical tensions. The calendar identifies several activities as virtual and lists selected venues, with some arrangements marked tentative or still to be confirmed.

The schedule does not establish that the meetings will produce a security agreement or adopt new anti-crime measures. Those outcomes would depend on later official decisions or statements. The next known step is the opening of the scheduled meetings on Aug. 10.

Separately, ASEAN’s calendar lists the ASEAN Socio-Cultural Community Coordinating Conference for Aug. 11–13 in Tagaytay, Philippines.

The transition is significant because Colombia is a major South American power. Its decisions can affect regional security, migration, trade, relations with Washington and ties with neighboring governments. The new administration’s direction will therefore be watched beyond the country’s borders, particularly as it responds to drug-trafficking groups and competition over ports and trafficking routes.

A new political direction

De la Espriella’s inauguration is part of what the AP described as a sequence of conservative governments gaining ground across Latin America. The Congressional Research Service has also documented major recent and upcoming leadership transitions across Latin America and the Caribbean, providing broader context for the region’s changing political landscape.

Colombia’s shift is notable in a country long associated with center-left and liberal coalitions. That does not mean every government in the region is moving in the same direction, or that Colombia has automatically abandoned earlier policies. The confirmed change is the transfer of power to a conservative president and the policy direction his administration has begun to establish.

The inauguration also creates a test for how political change will translate into government action. A conservative label identifies the broad orientation of the administration, but its lasting effect will depend on decisions made on security, regional diplomacy and other areas of public policy.

Security pressures at home

The new government inherits security problems involving drug gangs, coastal cities, ports and trafficking routes. The AP linked the presidential transition to conditions in coastal communities affected by drug gangs and to competition over routes and infrastructure used by trafficking groups.

De la Espriella has given Colombia’s military a more prominent role in security operations. That is an important policy direction, but it is not the same as a change in Colombia’s form of government. The available evidence establishes an expanded operational role for the military, not military rule.

The security challenge is also tied to geography. Coastal cities and ports can become points of competition when trafficking groups seek control of routes. Those pressures give the administration a domestic test with an international dimension: the movement of drugs, people and commercial goods can connect Colombian security decisions to conditions elsewhere in the region.

For residents of affected cities, the central question will be whether the government’s security approach changes conditions on the ground. The administration must address the activity of drug gangs while managing the consequences of competition over routes and ports. The inauguration marks the start of that responsibility, not a resolution of the problem.

Regional consequences

Colombia’s political change could influence regional security and diplomacy. A government that gives the military a more prominent role in security operations may affect how Colombia works with neighboring governments and international partners, although the inauguration itself did not establish a new regional agreement.

Relations with Washington will be an important part of that broader picture. Colombia’s security policies, its approach to trafficking routes and its position as a major South American power all make the country relevant to U.S. policy. The same issues can matter to neighboring governments because security networks, migration patterns and trade relationships cross national borders.

The regional conservative movement likewise has implications beyond electoral politics. It may shape debates over public security, the role of the military and relations among governments. But the durability and extent of that movement remain questions for future developments rather than settled conclusions.

What comes next

The immediate task for de la Espriella’s administration is to turn its stated security direction into action while confronting drug gangs and competition over coastal ports and trafficking routes. Those choices will help define the government’s relationship with Colombia’s military, affected communities, neighboring countries and international partners.

The August 7 inauguration is the confirmed political development. Its wider consequences will depend on how the new government handles domestic security and regional diplomacy, and whether the conservative shift produces durable changes in Colombia’s policies. For now, de la Espriella begins his presidency with both a new political mandate and a security challenge that reaches beyond Colombia’s borders.

The meeting was held in Manila, Philippines, under the Philippines’ 2026 chairship of the Association of Southeast Asian Nations. Participants also discussed strengthening the forum’s regional role and exchanged views on regional issues, according to the available ASEAN summary.

A long-term framework during a volatile period

The plan arrives as governments in Southeast Asia and the wider Indo-Pacific face overlapping pressures, including maritime disputes, major-power rivalry and energy shocks. Those issues have made regional communication and security cooperation more consequential, even as the available record does not list every provision of the new plan.

The forum’s adoption of a document covering 2026–2036 is the central decision from the Manila meeting. It establishes a stated framework for regional dialogue and cooperation over the next decade. The source material does not establish whether the plan creates binding commitments, and it should not be described as a treaty or a legally binding security pact.

That distinction matters for readers trying to assess what changed. The adoption records a diplomatic agreement among participants on a framework, but the available sources do not show that it settles individual territorial disputes or resolves disagreements in the South China Sea.

Energy security was part of the wider diplomacy

The regional discussions took place alongside concern about energy and price shocks affecting Southeast Asia. In reporting published before the meeting, the Associated Press said Southeast Asian ministers were expected to call for the reopening of the Strait of Hormuz during talks in Manila.

That report linked the planned diplomatic appeal to energy and price pressures in Southeast Asia. The report described what ministers were expected to call for; it does not establish that the call became a provision of the Manila Plan of Action. The available sources likewise do not establish the outcome of any specific discussion about the strait.

The energy issue illustrates the broader setting for the forum’s work: regional diplomacy was taking place while governments addressed security concerns and economic exposure beyond Southeast Asia. The adopted plan provides the longer-term framework, while the available record does not identify detailed implementation measures.

ASEAN’s wider regional outreach

ASEAN ministers also met with New Zealand in Manila on July 22, one day before the forum adopted the plan. The parties issued a joint statement on strengthening regional resilience, according to the ASEAN Secretariat’s record of the 2026 ministerial meetings.

The meeting also followed a significant change in ASEAN’s membership. ASEAN’s official portal identified Timor-Leste as the organization’s 11th member after its admission in October 2025. That membership figure provides current institutional context for the Philippines’ 2026 chairship and the regional diplomacy conducted in Manila.

Together, the forum’s plan, the ASEAN–New Zealand resilience statement and the organization’s expanded membership show a regional diplomatic agenda operating across security, resilience and institutional engagement. They are separate developments in the available record, rather than evidence that every participating government agreed on individual disputes.

What happens next

The Manila Plan of Action covers the period from 2026 through 2036. That is the next clear timeline supplied by the sources. The available ASEAN summary does not specify the plan’s full provisions, milestones or enforcement mechanisms, and the source packet does not identify a separate implementation deadline.

For now, the verified change is the adoption of the decade-long framework, not a settlement of the region’s disputes. Its practical significance will depend on how the forum uses the framework for future dialogue and security cooperation—an outcome that cannot yet be assessed from the available record.
