Chinese military planes delivered weapons to Cambodia in late June, weeks before a five-day border clash erupted with Thailand, according to Thai intelligence documents reviewed by The New York Times.
The Y-20 transport aircraft, nicknamed “Chubby Girls” for their wide bodies and heavy-lift capacity, made six flights to Sihanoukville, carrying rockets, artillery shells, and mortars packed into 42 containers. The shipments were stored at Ream Naval Base before being moved north to Cambodia’s disputed border with Thailand, near the Preah Vihear temple.
Cambodia and Thailand blamed each other for initiating the conflict in late July, which killed at least 40 people and displaced hundreds of thousands. Analysts said Cambodia’s arms buildup gave it a more assertive posture along the boundary than previously seen. Independent monitors confirmed that many of the rockets used by Cambodia were of Chinese origin, striking civilian areas in four Thai provinces.
Thailand’s Armed Forces confirmed the authenticity of the intelligence documents, while Cambodia acknowledged the shipments but described reports as misleading. Lt. Gen. Rath Dararoth, Cambodia’s secretary of state for defense, said the deliveries coincided with the conclusion of annual joint military exercises with China, although the exercise had ended weeks before the June shipments. China’s Defense Ministry did not comment.
Analysts noted that Cambodia’s rapid resupply likely extended its operational capacity during the border skirmish, even as Thailand quickly retaliated with F-16 airstrikes and superior firepower. The Thai intelligence reports detailed shipments of nearly 700 rounds for Soviet-era BM-21 rocket launchers, Type 90B and PHL-03 multiple launch rocket systems, and artillery for self-propelled and anti-aircraft systems.
The conflict centers on a centuries-old temple claimed by both nations. Cambodia had constructed a military base and roads near the temple, which analysts say reflects a deliberate militarization strategy. While China publicly denies supplying weapons for combat, the shipments highlight Beijing’s strategic influence in the region and complicate its role as a supposed neutral mediator.
