Thailand has released 18 Cambodian soldiers who were captured during deadly border clashes in July, following a ceasefire agreement reached between the two countries.
The handover marked a significant step in easing weeks of tension that escalated into widespread violence along the disputed border.
Thai officials said the release was delayed by a day due to concerns over alleged violations of the ceasefire agreement.
The transfer eventually went ahead after sustained diplomatic pressure from China aimed at ensuring the truce remained intact.
Fighting between Thailand and Cambodia intensified earlier this month after simmering tensions erupted into open conflict.
The clashes forced nearly one million civilians to flee their homes in border regions as security conditions deteriorated.
Under the ceasefire deal agreed on Saturday, both sides committed to freezing front lines and banning reinforcements.
The agreement also allowed displaced civilians living near the border to begin returning home as soon as possible.
The 18 Cambodian soldiers were escorted across a border checkpoint and formally handed over to Cambodian authorities.
The soldiers had been held since July, when an earlier round of fighting caused significant casualties on both sides.
