BANGKOK, Thailand -- Thailand and Cambodia reaffirmed their shaky ceasefire violation after days of fighting along their border, as China stepped into negotiate with the two countries.

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.
