ASEAN Haze Crisis Highlights Limits of Regional Cooperation and Implications for Japan

In a recent interview with CNA’s Asia Now programme, Helena Varkkey, associate professor at the Department of International and Strategic Studies, Universiti Malaya, warned that the Association of Southeast Asian Nations (ASEAN) continues to rely on diplomatic engagement rather than decisive action to address the ongoing trans‑boundary haze. Her assessment, recorded on 8 October 2026, underscores the structural constraints that shape ASEAN’s collective response and raises questions about how Japan, as a major regional stakeholder, might adjust its own policy and diplomatic posture toward the environmental and health challenges posed by the haze.

ASEAN’s Diplomatic Framework and Its Inherent Limitations

Varkkey emphasized that ASEAN’s response to the haze crisis remains largely confined to diplomatic channels and voluntary cooperation among member states. This approach reflects the organization’s foundational principle of non‑interference, which, while preserving national sovereignty, often hampers the ability to enforce binding environmental standards. The expert noted that the current mechanisms rely on consensus‑building and peer pressure rather than any supranational authority capable of imposing sanctions or mandatory remediation measures.

In practice, this diplomatic orientation translates into periodic ministerial meetings, joint statements, and the occasional coordination of fire‑fighting resources. However, Varkkey observed that these efforts have not evolved into a robust, enforceable framework capable of addressing the root causes of the haze, such as illegal land‑clearing and peatland degradation. The reliance on goodwill and mutual assistance, she argued, leaves the region vulnerable to recurring episodes whenever climatic conditions become conducive to large‑scale burning.

From a Japanese perspective, the limited scope of ASEAN’s diplomatic toolkit presents both challenges and opportunities. Japan’s Ministry of Foreign Affairs (MOFA) has traditionally supported ASEAN’s regional integration agenda, but the haze crisis tests the depth of that support. As Varkkey’s comments suggest, the effectiveness of diplomatic engagement alone may be insufficient, prompting Japanese policymakers to consider complementary avenues such as technical assistance, capacity‑building, and targeted investment in sustainable land‑use practices.

The Role of El Niño in Amplifying the Haze Situation

In the interview, Varkkey linked the intensity of the current haze to the broader climatic phenomenon of El Niño. She explained that El Niño’s impact on regional weather patterns, particularly the reduction of rainfall in parts of Indonesia and Malaysia, creates conditions that are highly conducive to forest and peatland fires. The expert’s analysis aligns with the scientific consensus that El Niño can exacerbate fire risk by extending the dry season and lowering soil moisture.

The El Niño connection adds a layer of complexity to ASEAN’s diplomatic response. Because the climatic driver is external and largely uncontrollable, member states must contend with an environmental stressor that can trigger cross‑border pollution even when domestic fire‑prevention policies are in place. Varkkey highlighted that this reality complicates the attribution of responsibility and, consequently, the willingness of governments to adopt stricter measures that might be perceived as punitive.

Japan, which monitors El Niño’s influence on regional weather through the Japan Meteorological Agency (JMA), can leverage its scientific expertise to support ASEAN’s early‑warning systems. By providing real‑time climate data and predictive modelling, Japan could enhance the region’s preparedness and potentially reduce the scale of fire outbreaks before they become trans‑boundary hazards. Such cooperation would fit within the broader framework of Japan‑ASEAN science and technology collaboration, a pillar of Japan’s foreign policy in the Asia‑Pacific.

Challenges to Imposing Stronger Measures Within ASEAN

According to Varkkey, the principal obstacle to stronger regional action lies in the divergent economic interests and governance capacities of ASEAN member states. Countries with extensive peatlands, such as Indonesia, face a tension between short‑term economic gains from land conversion and the long‑term environmental costs of haze. The expert noted that imposing uniform regulations would require consensus on issues that are politically sensitive and economically consequential.

Furthermore, Varkkey pointed out that enforcement mechanisms are uneven across the region. While some nations possess robust forest‑monitoring agencies, others lack the institutional capacity to detect and penalize illegal burning effectively. This disparity weakens the collective ability to implement coordinated fire‑prevention strategies and undermines the credibility of ASEAN’s diplomatic declarations.

Japan’s own experience with rigorous environmental regulation, overseen by the Ministry of the Environment (MOE) and the Ministry of Economy, Trade and Industry (METI), offers a comparative lens. Japanese policy often combines strict legal standards with substantial fiscal incentives to promote sustainable practices. In dialogues with ASEAN, Japan could share best practices on regulatory design, monitoring technology, and incentive structures, thereby supporting capacity‑building without imposing a one‑size‑fits‑all solution.

Economic and Health Implications for Japan

The trans‑boundary haze carries direct implications for Japan’s public health and economic sectors. Air quality monitoring stations across Japan have recorded elevated particulate matter levels during previous haze episodes, prompting public health advisories and affecting vulnerable populations. Varkkey’s interview, while focused on ASEAN dynamics, implicitly underscores the cross‑border nature of the problem, reminding regional partners that pollution does not respect political boundaries.

Economically, the haze can disrupt supply chains that involve ASEAN‑based manufacturers supplying components to Japanese firms. While Varkkey did not quantify the impact, the expert’s emphasis on the limited regional response suggests that prolonged haze events could increase logistical delays and raise operational costs for Japanese companies operating in the region.

In response, Japan’s Ministry of Health, Labour and Welfare (MHLW) has previously issued health guidelines for citizens during haze events, and the Ministry of Economy, Trade and Industry (METI) has encouraged firms to develop contingency plans. Varkkey’s analysis reinforces the need for these domestic measures to be complemented by proactive diplomatic engagement aimed at reducing the frequency and severity of haze incidents at their source.

Potential Pathways for Enhanced Japan‑ASEAN Collaboration

Building on Varkkey’s observations, several avenues emerge for Japan to deepen its engagement with ASEAN on haze mitigation. First, Japan could expand its technical assistance programmes under the Japan‑ASEAN Integration Fund, focusing on satellite‑based fire detection, real‑time data sharing, and the deployment of unmanned aerial vehicles for rapid assessment of fire hotspots. Such technology transfer would align with Japan’s strategic interest in promoting digital transformation and resilience in the region.

Second, Japan might consider joint research initiatives with ASEAN universities and think‑tanks to explore alternative land‑use models that balance economic development with environmental stewardship. By supporting pilot projects that demonstrate sustainable agriculture and peatland restoration, Japan could help create viable alternatives to slash‑and‑burn practices that fuel the haze.

Third, diplomatic channels could be leveraged to advocate for a more binding ASEAN agreement on fire management. While Varkkey highlighted the current reliance on diplomacy, Japan’s influence within the East Asia Summit and its longstanding partnership with ASEAN could be instrumental in encouraging member states to adopt a framework that includes clear reporting obligations, mutual assistance protocols, and, where feasible, compliance‑based incentives.

Long‑Term Outlook and the Need for Regional Resilience

Varkkey’s interview concluded with a sober reminder that the haze crisis is likely to recur as long as underlying drivers—such as land‑use change, weak enforcement, and climate variability—remain unaddressed. The expert’s emphasis on the limited scope of ASEAN’s current response suggests that without a shift toward more substantive collective action, the region will continue to experience periodic health and economic disruptions.

For Japan, the long‑term outlook calls for a balanced strategy that combines domestic preparedness with sustained regional engagement. Strengthening early‑warning systems, supporting capacity‑building, and fostering policy dialogue are all consistent with Japan’s broader objectives of promoting a stable, prosperous, and environmentally sustainable Asia‑Pacific.

In sum, the insights offered by Helena Varkkey illuminate both the constraints of ASEAN’s diplomatic approach and the opportunities for Japan to play a constructive role. By aligning technical expertise, policy experience, and diplomatic outreach, Japan can help transform the haze from a recurrent nuisance into a catalyst for deeper regional cooperation on environmental resilience.
