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 talks between commanders on both sides were seen as a crucial test of whether the cease-fire deal reached on Monday would result in a lasting peace.

Thailand’s military accused Cambodian forces on Wednesday of breaching a ceasefire agreement at three separate locations along the disputed border, warning that continued aggression could compel Thai forces to respond more decisively.
