On July 23, Thailand carried out airstrikes on Cambodian military positions near their long-disputed border, intensifying already high tensions between the two Southeast Asian nations. In response, Cambodia vowed to “respond decisively.

Cambodian border came to a halt Tuesday after military commanders from both countries met to enforce a ceasefire agreement reached a day earlier — a deal the Thai army accused Cambodia of violating.

The talks between commanders on both sides were seen as a crucial test of whether the cease-fire deal reached on Monday would result in a lasting peace.
