The June 2026 defense dialogues in Hanoi, paired with concurrent US Navy and Army cooperation missions in Central Vietnam, signal that the US-Vietnam security relationship has moved beyond symbolic gestures. What began as cautious tactical engagement is now a vital anchor for regional stability under the Comprehensive Strategic Partnership.
As Vietnam's Ministry of National Defense prepares for the Third Vietnam International Defense Expo in Hanoi this December, policymakers in both capitals face a key question: how to convert political momentum into durable, structured capabilities. Real partnerships depend on continuous adaptation, requiring Hanoi and Washington to broaden their defense architecture while respecting the strategic boundaries that define Vietnam's foreign policy.
Trust built on war legacy remediation
Decades of joint initiatives—from the Bien Hoa dioxin cleanup to unexploded ordnance clearance in provinces like Quang Tri—have served as the bedrock of the relationship. This cooperation is reciprocal: Vietnam's long-standing dedication to accounting for missing US personnel is matched by expanded Washington assistance in deploying advanced DNA analysis to identify fallen Vietnamese soldiers.
As this historic post-war reconciliation nears completion, it should no longer be treated as a standalone achievement but leveraged as a launchpad for modern security cooperation. To catalyze this next strategic phase, Washington and Hanoi should prioritize four decisive steps.
Deepening maritime security and domain awareness
The volatile security environment in the East Sea demands that maritime cooperation transcend basic hardware handovers. While past transfers of Hamilton-class cutters enhanced patrolling, the priority should shift toward real-time intelligence integration and secure, shared data networks.
Elevating Hanoi's capacity to counter gray-zone threats and monitor its exclusive economic zone secures Vietnamese waters and empowers the Vietnam Coast Guard to act as a resilient provider of humanitarian assistance, disaster relief, and search-and-rescue operations across critical international sea lanes. This aligns with broader regional efforts, such as Manila-Tokyo security ties, which also aim for stability rather than containment.
Catalyzing defense industry cooperation and tech transfer
December's Defense Expo in Hanoi provides the prime catalyst for US defense firms to pivot from a traditional vendor-purchaser model toward genuine industrial partnerships. Establishing maintenance, repair, and overhaul facilities on Vietnamese soil and co-producing dual-use technologies will accelerate Vietnam's goal of forging a self-reliant defense industry.
Realizing this vision requires Washington to dismantle lingering bureaucratic impediments, notably by streamlining International Traffic in Arms Regulations export controls and creating flexible statutory waivers under the Countering America's Adversaries Through Sanctions Act for legacy Russian hardware transitions. A reevaluation of Vietnam's market economy status and relaxation of outdated export controls are also necessary.
Crucially, such co-development unlocks a vital bilateral loop: US technology expands local capabilities, while Hanoi helps Washington secure and diversify critical technology supply chains through its expanding semiconductor and critical mineral sectors. This mirrors the kind of defense cooperation quietly bolstering deterrence seen between India and the Philippines.
Engaging regional actors and multilateral frameworks
Bilateral defense ties are most resilient when they reinforce, rather than bypass, regional architecture. US-Vietnam defense initiatives should therefore lock step with mechanisms from the Association of Southeast Asian Nations (ASEAN), particularly the Defense Ministers' Meeting Plus. At the same time, Washington and Hanoi should harmonize capacity-building efforts with shared regional partners like Japan and Australia.
Focusing on functional coordination—such as joint coast guard training and maritime law enforcement seminars—advances a free, open, and lawful Indo-Pacific without forcing rigid bloc politics or feeding zero-sum rivalries with Beijing. This approach echoes the debate in Japan over nuclear submarines, where defense consensus is being tested.
Investing in next-generation thinkers and doers
Strategic partnerships live and die by human networks, so both capitals should insulate the relationship by formalizing strategic dialogues designed for rising scholars and young military officers. Scaling up joint training and logistical funding for United Nations Peacekeeping Operations is another priority, especially given Vietnam's recently enacted Law on Participation in UN Peacekeeping Operations, which underscores Hanoi's desire to act as a responsible global security contributor outside the friction of major-power rivalries.
Expanding military education exchanges—such as sending more Vietnamese officers to US staff colleges—and building joint research pipelines for emerging tech talent will forge the resilient institutional tissue required to sustain cooperation over the long term.
This multifaceted expansion of defense cooperation is aligned with Vietnam's independent foreign policy. Adhering to the sovereign "Four No's" doctrine—which rules out military alliances, backing one country against another, hosting foreign bases, or using force in international relations—is not a barrier to engagement. Rather, it provides a predictable framework within which Washington and Hanoi can build a mature, resilient partnership that contributes to regional stability.
