Cambodia confirmed Tuesday that Thailand has unilaterally closed all border crossings between the two Southeast Asian nations, escalating tensions amid a dispute over cross-border crime prevention measures. The abrupt closure, announced by Thai Prime Minister Paetongtarn Shinawatra on Monday, marks a significant shift in regional diplomacy and trade dynamics.
Unilateral Closure Announced
Cambodian immigration chief Sok Veasna stated that authorities received formal notification of Thailand’s border shutdown on June 24, with all checkpoints now restricted to essential travel. The move follows Thailand’s pledge to combat transnational crime through tightened controls on vehicles, individuals, and commercial activities.
Economic and Security Measures
Thailand’s new restrictions include suspending fuel and electricity exports suspected of supporting illegal operations in Cambodia, along with internet service cuts to Cambodian government and military entities. Prime Minister Paetongtarn emphasized these measures aim to disrupt criminal networks operating across the 798-kilometer shared border.
Cambodia responded by halting fuel imports from Thailand and advising against non-essential travel to its western neighbor. The reciprocal measures highlight growing friction between the ASEAN members, whose bilateral trade exceeded $6 billion in 2023.
Humanitarian Exceptions
Both nations have maintained exemptions for students, medical patients, and critical goods transportation. However, the closure of seven provincial border crossings has already disrupted cross-border commerce and raised concerns among businesses reliant on the Thailand-Cambodia supply chain.
Analysts suggest the dispute could test ASEAN’s conflict resolution mechanisms while impacting regional economic integration efforts. The developments come as Southeast Asia faces increased scrutiny over cross-border crime and cybersecurity challenges.
