Thailand and Cambodia agreed to an “immediate” ceasefire on Saturday, the two countries said in a joint statement, pledging to end border clashes that killed dozens of people.
UN Secretary-General Antonio Guterres welcomed the announcement “as a positive step towards alleviating the suffering of civilians… and creating an environment conducive to achieving lasting peace”, spokesman Stephane Dujarric said.
At least 47 people were killed and more than a million displaced in three weeks of fighting with artillery, tanks, drones and jets, according to official tallies.
The conflict spread to nearly every border province on both sides, shattering an earlier truce for which US President Donald Trump took credit.
US Secretary of State Marco Rubio on Saturday welcomed the ceasefire, calling on both sides to “immediately honor this commitment”.
