Thailand and Cambodia have signaled their readiness to negotiate a ceasefire after mediation by U.S. President Donald Trump.

The leaders of Cambodia and Thailand agreed to a ceasefire in a bid to bring an end to their deadliest conflict in more than a decade.

A ceasefire between Cambodia and Thailand appears to be holding, hours after it came into effect at midnight local time (1 p.m. ET Monday), following days of clashes across the two countries’ disputed border.
