The New Age of ‘Minilateralism’
In the world of geopolitics, the old model of sprawling, treaty-bound alliances is being supplemented by a new, more agile framework: the trilateral, or ‘minilateral’, security agreement. These are often three-way partnerships focused on specific threats
and shared objectives, allowing for deeper, more targeted cooperation without the institutional baggage of larger organisations. Unlike broad alliances that require consensus among many members, these smaller groups can move quickly to coordinate on defence technology, conduct joint military exercises, and share intelligence. This trend reflects a pragmatic response to the increasingly complex security dynamics of the Indo-Pacific, where a one-size-fits-all approach no longer suffices. These pacts create a web of overlapping security relationships, strengthening deterrence by making the region's power balance more resilient and networked.
Case Study: The US-Japan-Philippines Pact
A prime example of this new model is the burgeoning trilateral partnership between the United States, Japan, and the Philippines. Solidified in recent summits, this cooperation is aimed directly at enhancing security in the South China Sea and the broader Western Pacific. The agreement facilitates everything from joint naval patrols and military drills to enhanced intelligence sharing and Japanese-funded defence equipment for the Philippines. Recent joint exercises near the strategic Luzon Strait, which separates the Philippines and Taiwan, highlight the pact's operational focus. This trilateral arrangement connects two key US treaty allies in Asia, creating a more integrated security chain and a coordinated front. It represents a significant strategic alignment, institutionalizing a cooperative framework that allows for better planning and more effective joint operations in critical maritime domains.
The Dragon in the Room
The primary driver behind this surge in minilateral pacts is the need to create a credible counterweight to China's growing assertiveness. Beijing's expansive claims in the South China Sea, its militarization of reclaimed islands, and its increasingly aggressive behaviour toward Philippine vessels have prompted regional nations to seek new security arrangements. China has strongly criticised these developments, labelling them as “bloc politics” and attempts to form an “anti-China gathering” reminiscent of a Cold War mentality. Beijing views these pacts as external interference designed to contain its rise, arguing its actions in the region are lawful and appropriate. However, for the Philippines and Japan, this cooperation is a defensive measure to uphold international law and ensure freedom of navigation in vital sea lanes.
Recalibrating the Regional Power Balance
These three-way agreements are actively reshaping regional calculations. For countries like the Philippines, they provide a much-needed security backstop and access to advanced military technology and training, enhancing their ability to deter coercion. For the United States, these arrangements strengthen its hub-and-spokes alliance system by fostering stronger connections between its partners. This creates a more distributed and resilient security network that is less reliant solely on American power. These pacts also present a challenge to the traditional centrality of ASEAN, as some member states pursue security interests outside the consensus-based framework of the bloc. This proliferation of minilaterals, including others like AUKUS (Australia, UK, US), indicates a broader geopolitical rearrangement in the Indo-Pacific.
What This Means for India
For New Delhi, this trend presents both opportunities and challenges. India has historically championed a policy of “strategic autonomy,” avoiding formal military alliances while building issue-based partnerships. The rise of minilaterals aligns well with this flexible approach. India is already a key member of the Quadrilateral Security Dialogue (the Quad), alongside the US, Japan, and Australia, which operates on a similar principle of like-minded cooperation. This new web of security pacts in the Indo-Pacific can complement India’s own efforts to ensure a stable, rules-based order. However, it also increases pressure on India to define its role more clearly. While New Delhi has deepened its security ties with Quad members and other regional powers, it remains wary of being drawn into a rigid, anti-China coalition. Navigating this evolving landscape will require a delicate balancing act: contributing to regional security without compromising its long-held principle of independent foreign policy.
