Thailand's military has closed border crossings into Cambodia to almost all travellers, including tourists and traders, citing security concerns as tensions between the two Southeast Asian neighbours remain escalated over a simmering border dispute.

Thailand is imposing new border restrictions including blocking tourists from entering Cambodia as the two countries engage in retaliation in their border dispute.

The reescalation of conflict was sparked on May 28, when a Cambodian soldier was killed in an early morning clash between both nations’ troops, in an area called the Emerald Triangle—the shared border between Thailand, Cambodia, and Laos. The area remains disputed as both Thailand and Cambodia lay claims to parts of the region.
