Supply chain concerns may have been a major factor in pausing the recent conflict.

Thailand’s army warned that it may have to “exercise the right of self-defense” in response to continuing incidents it blames on Cambodia, in which Thai soldiers patrolling along the two countries’ border have been wounded by land mines.

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.
