The long running border dispute flared up again earlier this month, breaking a previous truce and leaving at least 47 people dead, according to official figures. Nearly one million people have also been displaced by the fighting.
In the statement, signed by the defence ministers of both countries, the two sides agreed to an immediate ceasefire effective from 12:00 noon local time on December 27, 2025. The ceasefire covers all types of weapons and prohibits attacks on civilians, civilian infrastructure and military targets in all affected areas.
Both sides also agreed to freeze troop movements and allow civilians living in border regions to return to their homes as soon as possible. The statement added that the two countries would cooperate on demining operations and efforts to combat cybercrime.
The ceasefire comes into force at 12:00pm local time, or 0500 GMT, bringing a halt to fighting over several ancient temples located in disputed areas along the shared border.
The agreement follows three days of border talks announced after a crisis meeting of foreign ministers from the Association of Southeast Asian Nations, of which both countries are members.
The United States, China and Malaysia also urged the two sides to restore the ceasefire.
Earlier, the three countries helped broker a truce in July to end five days of intense clashes, but that ceasefire later collapsed.
