Middle East shock tests ASEAN energy transition momentum

When Brent crude approached $120 per barrel, fuel stations in the Philippines paused operations and ASEAN leaders shortened summit scheduling to prioritize emergency energy coordination. Southeast Asia is now absorbing spillovers from a conflict unfolding thousands of kilometers away.

For ASEAN, the Middle East crisis is no longer a distant geopolitical headline. Higher fuel costs, disrupted logistics, inflationary pressure and food security risks are now filtering into households, factories and transport systems across the region.

At the 48th ASEAN Summit in Cebu, Philippines, the Middle East crisis dominated discussions. Leaders cautioned that heavy dependence on imported energy could leave Southeast Asia exposed to sustained economic pressure even if tensions cool. Member states discussed accelerating regional fuel coordination, diversifying import sources, expanding electric mobility and advancing the ASEAN Power Grid (APG).

The pressure is especially visible in the Philippines, where roughly 96% to 98% of oil supply originates from the Middle East. Recent shortages led to temporary shutdowns of hundreds of fuel stations and raised concerns over aviation fuel stability.

The crisis is also reshaping policy thinking. Energy security is gaining priority while geopolitical shocks are indirectly encouraging greater investment in renewables.

Lu Ruquan, president of the Economics and Technology Research Institute of China National Petroleum Corporation, has previously noted that rising geopolitical volatility is reshaping global energy trade patterns and accelerating diversification in supply chains and energy technologies.

This shift is increasingly visible across ASEAN. Indonesia, Thailand and Vietnam have expanded electric vehicle and battery investment plans to reduce exposure to fuel price volatility. Indonesia's business community has also linked stronger clean energy cooperation with long-term cost stability.

The APG is also gaining renewed urgency. Previously slowed by financing constraints and regulatory fragmentation, it is now increasingly seen as essential for regional resilience against external energy shocks.

ASEAN ministers said this week that regional energy integration and cross-border infrastructure will be central to strengthening resilience.

China is playing an increasingly visible role in this transition.

As Southeast Asian countries accelerate renewable deployment, Chinese firms are expanding investment in solar, wind, batteries and electric vehicles across the region.

One example is Goldwind's Kalayaan 2 wind project in the Philippines. The project, with 17 turbines and 100.8 MW capacity, is expected to generate around 300 million kWh annually and ease local power constraints. More than 60% of its workforce is locally hired.

China's EV and battery industries are also expanding rapidly in ASEAN, supported by policy incentives and growing regional demand for affordable electric mobility.

Another example is Chinese automaker Chery's newly opened NEV manufacturing plant in Thailand's Rayong province. Equipped with battery production lines and advanced manufacturing systems, the facility is designed to support Thailand's ambition of becoming a regional EV hub while strengthening local supply chains.

Analysts note that high oil prices are improving the competitiveness of electric mobility while fiscal pressure is pushing governments to prioritize domestic renewable energy development over costly fuel imports.

Zhai Kun, professor at the School of International Studies, Peking University, has argued that infrastructure connectivity and energy interconnection are becoming central pillars of China-ASEAN cooperation amid rising uncertainty.

Still, ASEAN's green transition faces significant constraints.

Renewable energy requires substantial upfront capital while many Southeast Asian economies face slowing growth, currency volatility and rising debt burdens.

Some economies also remain heavily dependent on fossil fuel revenues. Brunei, for example, continues to rely significantly on oil and gas exports for government income, making rapid transition more complex.

Regional disparities further complicate the picture. Singapore has stronger financing capacity and advanced grid systems, while countries such as Laos and Myanmar face infrastructure gaps.

There is also a geopolitical balancing act, as ASEAN states navigate energy cooperation with China, investment ties with the United States and broader major power competition.

Yet despite these constraints, the current crisis may mark an inflection point.

For decades, energy transition in Southeast Asia was framed largely in environmental terms. The Middle East crisis is reframing it in economic and strategic terms, where energy security, resilience and geopolitical risk management are becoming equally central.

In this sense, oil shocks are increasingly shifting from temporary crises into structural catalysts shaping the region's energy future.
