The Senate Military Committee is preparing to summon the Ministry of Energy and the Customs Department to explain the controls over oil shipments to Cambodia after discovering traders exploiting the war to smuggle fuel from Malaysia and Singapore to assist Cambodia.
On 22 December 2025, Senator Chaiyong Maneerungsakul, secretary of the Senate's Military and State Security Committee, stated that at the committee meeting on 23 December at 09:00, they will examine the Thailand-Cambodia disputes that have led to fighting along the border across seven provinces. General Sawat Tatsana, chairman of the committee, will invite the Permanent Secretary of the Ministry of Energy, the Director-General of the Customs Department, and the Secretary-General of the Marine Interests Protection Command Center (MPCC) to explain controls over the export of fuel and military supplies, interception of oil and military materials at sea in high-risk areas, and other risk factors related to sovereignty and national security. Natural routes still see smuggling of agricultural goods from Cambodia, with military supplies exported from Thailand to support Cambodia. There is also suspiciously large fuel shipments to Laos via the Chong Mek border checkpoint in Ubon Ratchathani province.
Reports indicate a smuggling network transporting illicit oil from Malaysia and Singapore to Cambodia by sea. The committee views these events as suspicious, suspecting that some traders and certain agencies may be exploiting the war for profit while ignoring irregularities, causing serious harm to national security.
