What is ADMM-Plus JCA?

ADMM-Plus JCA refers to a Joint Cooperation Activity conducted under the ASEAN Defence Ministers’ Meeting-Plus framework. It enables participating armed forces to undertake coordinated professional activities and improve their ability to operate together. The programme can include harbour interactions and sea-phase activities designed around communication, coordination and maritime procedures.

ADMM-Plus connects the ten ASEAN Member States with Australia, China, India, Japan, New Zealand, South Korea, Russia and the United States. These eight states are collectively called the Plus Countries. The mechanism encourages practical defence cooperation while retaining ASEAN’s central role in the regional security architecture.

Why is ADMM-Plus JCA in News?

Indian naval ships INS Sahyadri and INS Kulish reached Subic Bay in the Philippines to participate in ADMM-Plus JCA. Maritime forces from ASEAN members and the eight partner countries joined professional harbour and sea-phase engagements. The activity aims to enhance interoperability, build mutual understanding and deepen regional maritime cooperation.

Subic Bay is an embayment of the South China Sea on the western coast of Luzon Island. Its location gives the activity wider strategic relevance amid concerns about safe navigation, maritime incidents and regional stability. The official PIB release outlines India’s participation and the cooperation objectives.

Key Features

The activity combines operational engagement, confidence building and ASEAN-led multilateralism within one practical defence framework.

• Broad regional participation: ADMM-Plus JCA brings together maritime forces representing Southeast Asian states and major Indo-Pacific powers with varied naval capabilities.
• Harbour-phase engagement: Professional interactions allow participating personnel to discuss procedures, exchange operational knowledge and establish working relationships before sea activities.
• Sea-phase cooperation: Coordinated maritime activities help naval forces understand common procedures and communicate effectively during complex multinational operations.
• ASEAN-led framework: The activity reinforces ASEAN centrality by placing the regional organisation at the centre of wider defence cooperation.
• Practical capacity building: Participation helps defence establishments improve coordination for maritime security, emergency response and other shared regional challenges.

Challenges

Defence cooperation must navigate strategic competition, different national capabilities and unresolved maritime disagreements across the Indo-Pacific.

• Divergent strategic interests: Participating countries hold different positions on regional disputes, military partnerships and the wider balance of power.
• Trust deficit: Competition among major powers can restrict information sharing and reduce the ambition of multinational defence activities.
• Capability differences: Unequal technology, training and logistical capacity can complicate the design of activities suitable for every participating force.
• Operational compatibility: Different communication systems, command structures and professional procedures may limit coordination during time-sensitive maritime situations.
• Consensus requirements: ASEAN-led mechanisms depend on consultation and gradual agreement, which can slow responses to rapidly developing security concerns covered under international relations developments.

Way Forward

Future ADMM-Plus JCA programmes should adopt clear operational objectives, standard communication procedures and regular post-activity assessments. Members can expand cooperation around maritime domain awareness, search and rescue, humanitarian assistance and disaster response. Repeated professional interaction can gradually strengthen trust without forcing countries into formal military alignments.

India should continue supporting an open, inclusive and ASEAN-centred architecture through sustained naval engagement and capacity-building partnerships. Practical cooperation must complement diplomatic efforts to preserve peace, freedom of navigation and respect for international law. The official ADMM-Plus platform identifies maritime security among its seven areas of defence cooperation.
