Cambodia Halts Fuel Imports from Thailand Amid Border Dispute Escalation

PHNOM PENH: In a significant move reflecting escalating tensions over a border dispute, Cambodia’s Prime Minister Hun Manet announced on June 22, 2025, that the country would cease all fuel imports from neighboring Thailand. This decision follows a series of confrontations between Cambodian and Thai troops in a contested area known as the Emerald Triangle, where the borders of Cambodia, Thailand, and Laos converge.

The announcement was made via a Facebook post from Hun Manet, stating, “Starting from midnight tonight, all fuel and gas imports from Thailand will be halted.” He reassured the public that energy companies would be able to source adequate supplies from alternative markets to meet domestic demands.

This halt in imports comes after a Cambodian soldier was killed in May during clashes along the border, escalating tensions between the two nations. In retaliation to ongoing disputes, Cambodia closed two border crossings on the same day, while Thailand imposed restrictions on various checkpoints, citing national security concerns.

According to the World Bank, Thailand was Cambodia's third-largest trading partner in 2022, with total imports amounting to approximately $3.8 billion, of which fuels constituted 27%. The economic ramifications of this decision could be profound, impacting not only fuel supply but also broader trade relations.

Additionally, political turmoil has ensued in Thailand following the leakage of a phone call between Prime Minister Paetongtarn Shinawatra and former Cambodian leader Hun Sen. This incident has led to calls for Shinawatra’s resignation, and her ruling party’s largest coalition partner withdrew support in light of the controversy.

In a further sign of the deteriorating diplomatic relations, Cambodia's Foreign Ministry urged its citizens to avoid unnecessary travel to Thailand, while Thailand’s consular department advised its citizens in Cambodia to steer clear of protest areas.

Military tensions were exacerbated by Cambodia’s defense ministry accusing the Thai army of violating an agreement by escorting approximately 150 cyclists to a disputed temple in the border region. The Thai military has rejected these claims, attributing the situation to a misunderstanding.

Experts suggest that the cessation of fuel imports could have long-lasting effects not only on the economic stability of Cambodia but also on regional diplomatic relations. Dr. Emily Chan, a political analyst at the Institute of Southeast Asian Studies, commented, “This decision by Cambodia may serve as a tactical maneuver to assert its sovereignty, but it risks exacerbating tensions and could lead to further retaliatory measures from Thailand.”

As both nations navigate this complex geopolitical landscape, the future of their bilateral relations remains uncertain. Observers are keenly watching how this conflict will unfold, particularly as both governments face internal pressures and public scrutiny. With the situation evolving rapidly, the potential for further diplomatic strain looms large, making it imperative for both countries to seek a resolution to avoid further escalation.
