Thailand has closed all land border crossings with Cambodia following a sharp escalation in diplomatic tensions fueled by a growing dispute over transboundary scams and territorial control.

The sudden move has stranded numerous tourists and disrupted trade routes, prompting backlash from Cambodian officials, who accuse Bangkok of economic aggression.

Military authorities in Thailand have cited national security concerns for the closures, while Cambodian leaders warn of retaliatory measures if the standoff is not resolved diplomatically.
