ASEAN’s Response to South China Sea Clashes

ASEAN found itself at a strategic crossroads in July 2025 as flare-ups in the South China Sea tested the limits of its unity and diplomatic resolve. As tensions escalated between claimant states and China, ASEAN leaders gathered for their annual summit with the task of balancing national interests, regional cohesion, and relations with Beijing. The summit concluded with carefully crafted language, signaling intent to uphold international law and accelerate the maritime Code of Conduct, yet fell short of robust mechanisms to deter aggressive maneuvers. This article examines ASEAN’s collective response, providing insight into the summit’s outcomes, the historical framework that shaped its stance, the latest developments influencing its posture, and the broader implications for regional security and global geopolitics.

ASEAN’s engagement in the South China Sea traces back to diplomatic initiatives in the early 1990s, culminating in the 2002 Declaration on the Conduct of Parties (DOC) with China. That pact intended to promote safe and peaceful coexistence pending a formal Code of Conduct (CoC). Despite repeated promises, including high-profile statements in 2018 and a 2019 framework agreement, progress has been slow and multipolar tensions have overtaken confidence-building measures. While some ASEAN members pursued bilateral deals with China—accepting coercive fishing zones or investment incentives—others, like the Philippines and Vietnam, pushed back through legal claims, coast guard deployments, and international arbitration. These divides have frequently stymied collective action and prevented ASEAN from presenting a firm front during maritime crises.

In the first half of 2025, Chinese patrol vessels continued to operate aggressively around Scarborough, Reed Banks, and the Spratlys, triggering multiple standoffs with Philippine and Vietnamese vessels. These incidents increased pressure on ASEAN representatives to respond. By May, IISS analysts warned that ASEAN needed a robust crisis-response mechanism to preserve credibility and regional order. The June ASEAN–China informal dialogue produced little beyond a joint statement emphasizing adherence to UNCLOS and support for the CoC’s accelerated conclusion, but offered no timetable or enforcement arrangements to prevent future standoffs. As a framework, this exemplified ASEAN’s traditional norm of consensus above action, even as regional actors faced growing coercion.

When ASEAN leaders met in July 2025, the summit outcome reflected the bloc’s habitual balance between principle and pragmatism. The final chairman’s statement reaffirmed the imperative of ASEAN unity, respect for international law, and resumption of CoC negotiations. Philippine President Marcos Jr. was the summit’s most vocal critic, urging a firmer stance, citing harassment of Filipino vessels and inadequate deterrence. He called for a CoC with enforcement teeth and formal crisis-management protocols. Yet Cambodia and Laos, closely aligned with China, resisted efforts to define intrusive behavior, limiting ASEAN’s statement to urging "self-restraint" and "resumption of dialogue" without reference to specific incidents or sanctions.

Meanwhile, Vietnam and Malaysia quietly engaged in a strategy of simultaneous deterrence and diplomacy. Vietnam, backed by coast guard modernization and recent island upgrades, refrained from unilateral provocation but lobbied for clause-based alerts under the ASEAN-China joint working group. Malaysia, hosting trilateral coast guard exercises with Indonesia and Australia in June, worked behind the scenes to expand that track through ASEAN frameworks. Yet, the absence of explicit commitment to regional patrols or a surveillance network highlighted the limitations of ASEAN’s consensus-driven approach.

The implications of ASEAN’s outcome are far-reaching. On one level, the summit reinforced a persistent gap between ASEAN’s diplomatic rituals and the realities of power projection in contested waters. The bloc’s lack of tangible crisis-response architecture raised concerns among external partners in the US, EU, and Japan, potentially inviting deeper security engagement outside ASEAN-led structures. At the same time, ASEAN members appeared to acknowledge the need for functional cooperation, as indicated by emerging support for trilateral exercises and maritime domain awareness initiatives. Although formal enforcement measures remain absent, infrastructural and technological foundations are being laid for future collective deterrence.

From a broader geopolitical perspective, ASEAN’s July 2025 posture illustrates the limits of soft power diplomacy in waters increasingly defined by hard power. With respect for UNCLOS and calls for restraint remaining central to the narrative, ASEAN risks diminishing relevance unless it transitions toward operational follow-through. The growing involvement of external actors like Australia, Japan, and the United States is likely to intensify if ASEAN fails to demonstrate internal coherence. Simultaneously, ASEAN’s maintenance of dialogue mechanisms—despite criticism—reflects its enduring role as a critical diplomatic convenor, even as its functional capacity is tested.

If the Code of Conduct remains stalled, ASEAN may find itself forced to adapt incrementally, enhancing cooperation through ad hoc security arrangements before formal agreement is reached. Already, maritime awareness partnerships driven by Vietnam and Malaysia involving Australia and Japan could anchor ASEAN’s informal crisis protocols, complemented by back-channel dialogues with China. ASEAN’s future in the maritime domain may thus be shaped less by declarations and more by practical coalitions built beneath the formal summit table.

The success of ASEAN’s response in July 2025 may hinge less on rhetoric than on implementation. To maintain regional relevance, ASEAN must operationalize its foundations: invest in maritime domain awareness systems across member states, deploy coast guard cooperation under ASEAN law enforcement frameworks, and elevate the CoC process to include staged commitments and dispute prevention tools. External partners must encourage these steps while respecting ASEAN’s centrality, allowing the bloc to evolve without eclipsing its diplomatic identity.

ASEAN’s response to the July 2025 South China Sea clashes reflects enduring paradoxes. It remains diplomatically agile but institutionally fragile, principled yet reactive, and consultative while lacking enforcement means. As long as ASEAN preserves its convening power, dialogue advantages, and symbolic relevance, it also risks losing strategic credibility if it fails to slow competitive escalation. In the dynamic geopolitics of the Indo-Pacific, the bloc’s next moves—whether covert patrols, joint surveillance, or renewed pressure on CoC negotiations—will determine whether ASEAN evolves into a governing actor or remains a forum of empty statements.
