Long-simmering tensions between Thailand and Cambodia escalated to deadly violence on July 24, setting off five days of military clashes at multiple spots along the roughly 800-kilometer (500 mile) border.

The acrimonious dispute, which flared into violence last week, concerns much more than a few square kilometers of rugged territory.

Clashes on the Thailand–Cambodia border trigger martial law, disrupt trade flows, and raise investor risk across both economies.
