This decision followed a land mine explosion on Monday that injured two Thai soldiers in the disputed border region.
Thai Prime Minister Anutin Charnvirakul stated that hostility had not decreased and that all truce actions would halt until Thailand's demands were met.
The ceasefire, signed last month after a five-day conflict, included Thailand releasing 18 Cambodian soldiers and both nations removing weapons and land mines.
Thailand will postpone the release of the captured Cambodian soldiers, accusing Cambodia of obstructing mine clearance and laying new mines, which Cambodia denies.
