Beijing’s Selective Fuel Exports Highlight Growing Energy Vulnerability in Southeast Asia

While Beijing officially locked its energy borders in mid-March to prioritise domestic reserves, select Chinese cargoes are quietly slipping through. Over the final weekend of March 2026, tankers carrying diesel and distillate fuels arrived at ports in the Philippines and Vietnam. 

Why Did China Impose Fuel Export Curbs in the First Place?

The Middle East conflict disrupted the Strait of Hormuz, threatening domestic fuel supplies across Asia. Beijing responded on March 12, 2026, with an unannounced ban on diesel, gasoline, and jet fuel exports to insulate its own economy before shortages hit.

The export curbs cut off a $22 billion supply chain, removing China as a major swing supplier and setting the stage for the regional scramble that followed.

Which Countries Are Receiving Chinese Cargoes and Seeking Help?

Bangladesh, the Philippines, Thailand, Malaysia, and Australia have turned to China for relief, as per Modern Diplomacy. Tankers Ding Heng 36 and Auchentoshan delivered over 260,000 barrels of diesel to the Philippines, while Great Ocean delivered 100,000 barrels of distillate fuels to Vietnam, according to Bloomberg. Dhaka asked China to honour existing fuel contracts and Malaysia warned the ban would worsen fertiliser rationing.

How Are the Export Curbs Pushing Southeast Asia Toward an Economic Crisis?

China's export curbs removed a critical buffer from regional energy markets. With the Strait of Hormuz disrupted and Chinese cargoes absent, governments are competing for shrinking fuel stocks and rising import costs. For energy-import-dependent economies across Southeast Asia, the double shock is accelerating a broader economic squeeze.

How Badly Are These Nations Affected by the Energy Shortage?

Diesel derivatives in Asia surged to $150 a barrel on March 17, jet fuel to $163, and gasoline to $139.80, up from pre-war levels of $79 to $92, according to Modern Diplomacy. The Philippines declared a national energy emergency after fuel prices doubled. China had supplied a third of Australia's jet fuel and half of the Philippines' and Bangladesh's fuel needs in 2024.

Will China Extend Fuel Exemptions Into April?

China is poised to extend its export curbs into April, five industry sources told Reuters. Discussions for limited diesel, jet fuel, and gasoline volumes to Southeast Asian countries are ongoing, with permitted Chinese cargoes potentially totalling up to 150,000 metric tons.

Where Is Southeast Asia Turning for Energy as Chinese Cargoes Fall Short?

With Chinese cargoes restricted, Southeast Asian nations are turning to Russia as a key alternative, with Singapore, Malaysia, the Philippines, and Indonesia among likely recipients of Russian fuel oil, according to Reuters. The Philippines and Thailand have also increased coal-fired power to reduce dependence on constrained LNG supplies.

What Does China's Selective Approach Mean for the Region?

Analysts expect China to resume energy exports selectively once domestic needs are secured. Matthew Biggin, a senior commodities analyst at BMI, told Agriculture of America: "This pattern is consistent. China restricts supplies rather than coming to the rescue." The region's dependence on Beijing for Chinese cargoes remains deep.
