The release of the soldiers, who were captured by Thailand in July this year, is being carried out as a show of "goodwill and to build trust," according to a statement from the Thai Foreign Ministry.
The ceasefire between Thailand and Cambodia officially came into effect on Saturday after months of unrest. The countries have previously agreed to two ceasefires, both of which have broken down.
In recent weeks of fighting between the two countries, at least 47 people have been killed and more than a million people have been forced to leave their homes.
