Coast Quad and the Wilmington Declaration: Quad’s New Maritime Strategy in the Indo-Pacific -

The 6th Quad Foreign Ministers’ Summit, held in Washington D.C. in July 2025, marked a pivotal expansion of the Quad’s Indo-Pacific strategy. While military cooperation has long defined the security posture of the Quadrilateral Security Dialogue (Quad), this summit elevated a new frontier: civilian maritime law enforcement. The term “Coast Quad”—informally coined by analysts now refers to the joint efforts of the four nations’ coast guards: the U.S. Coast Guard, Japan Coast Guard, Australia Border Force, and the Indian Coast Guard. Their aim: to uphold maritime rules and counter non-traditional threats across the Indo-Pacific.

This move to formalize coast guard-level collaboration stems from growing concerns over illegal fishing, maritime piracy, human trafficking, and coercive behavior in disputed waters. The Coast Quad introduces a more inclusive, non-provocative arm of Quad cooperation one that prioritizes rule of law, maritime domain awareness, and regional capacity building over military deterrence.

Wilmington Declaration: The Foundation of the Coast Quad

To understand the Coast Quad’s significance, one must trace it back to the Wilmington Declaration, issued during the 5th Quad Leaders’ Summit in Wilmington, Delaware (September 2024). This landmark declaration laid out the Quad’s renewed commitment to a “free, open, inclusive, and resilient Indo-Pacific”, explicitly identifying non-military maritime cooperation as a strategic priority.

Among its major announcements:

The launch of a Quad-at-Sea Ship Observer Mission, enabling each nation’s coast guards to monitor key maritime zones collectively.
The expansion of MAITRI (Maritime Initiative for Training in the Indo-Pacific), which now includes civilian law enforcement drills and capacity building.
A commitment to strengthen the Indo-Pacific Maritime Domain Awareness (IPMDA) initiative, using satellite and open-source tracking tools to monitor vessels, especially in regions vulnerable to IUU (Illegal, Unreported, Unregulated) fishing.

This marked the first time the Quad formally prioritized coast guard coordination, elevating it to a recurring feature of their multilateral strategy. The Wilmington Declaration thus serves as the strategic blueprint for the Coast Quad—a tool of “non-provocative deterrence” in maritime diplomacy.

Coast Quad in Action: 6th Summit Announcements

At the July 2025 Summit, the Coast Quad concept was operationalized. The joint statement issued by the foreign ministers reaffirmed their dedication to upholding freedom of navigation, protecting marine ecosystems, and resisting any unilateral attempts to change the status quo at sea.

Key developments included:

Official activation of the Quad-at-Sea Observer Mission, with deployments set to begin in the Indian Ocean, South China Sea, and Pacific Island waters by the end of 2025.
Expansion of joint training exercises under MAITRI, focusing on maritime search and rescue, disaster relief, oil spill response, and transnational crime enforcement.
Increased information-sharing through IPMDA, giving small Indo-Pacific nations access to real-time tracking of foreign vessels in their Exclusive Economic Zones (EEZs).

Why Coast Guard Collaboration Matters

Unlike naval exercises that often raise tensions with China, the Coast Quad offers a law-enforcement alternative—a mechanism to:

Combat “gray-zone” coercion, such as China’s use of fishing militias and water cannons.
Promote transparent maritime governance through shared patrols and vessel tracking.
Build trust with ASEAN nations, many of whom hesitate to participate in military-centric initiatives but are willing to engage in non-military patrols.

This layered approach reflects the Quad’s shift toward soft security and inclusive diplomacy, reinforcing a rules-based maritime order without escalating military confrontation.

India’s Role in the Coast Quad

India, with its strategic location in the Indian Ocean, has emerged as a cornerstone of Quad’s maritime strategy. The Indian Coast Guard will host one of the inaugural Quad-at-Sea exercises near the Andaman and Nicobar Islands in early 2026. India’s leadership in humanitarian assistance, such as during the 2004 tsunami and Cyclone Mocha (2023), makes it a natural anchor for regional safety and disaster coordination.

Challenges and Chinese Response

Unsurprisingly, the Coast Quad has drawn sharp criticism from Beijing. Chinese foreign ministry statements labeled the initiative a “thinly veiled attempt to militarize law enforcement,” even though the operations are civilian-led. However, maritime experts argue that the Quad’s coast guard strategy is both legal and necessary in regions facing increased surveillance gaps and rising maritime tensions.

Looking Ahead: The Future of the Coast Quad

The Coast Quad may soon expand its scope:

Observer status to ASEAN coast guards, such as Vietnam and the Philippines.
Collaboration with regional multilateral forums like the Indian Ocean Rim Association (IORA).
Use of digital maritime maps, powered by artificial intelligence, to forecast illicit activity.

With the next Quad Leaders’ Summit scheduled in India in 2026, the world will watch how this civilian maritime partnership continues to evolve—potentially becoming the Quad’s most successful and unifying initiative.

Conclusion: Toward a Civilian Shield in Troubled Waters

The Coast Quad, rooted in the Wilmington Declaration, reflects the Quad’s pivot toward soft maritime power. In an era of rising sea-based competition, its emphasis on coast guard collaboration, law enforcement training, and shared intelligence sends a powerful message: peace at sea can be achieved not only through warships but through coordination, capability building, and collective vigilance.

As the Indo-Pacific navigates turbulent waters, the Coast Quad emerges as both a stabilizer and a symbol of democratic resilience.
