BANGKOK — Thailand and Cambodia reaffirmed their shaky ceasefire on Wednesday after China helped mediate a peace process to end days of border fighting.

Thailand and Cambodia on Wednesday reaffirmed their commitment to a ceasefire agreement following fresh fighting along their shared border, after China stepped in to mediate at an informal meeting in Shanghai.

A ceasefire between Thailand and Cambodia appeared to largely be holding on Tuesday as military commanders from both countries met for negotiations, even as the Thai army accused Cambodian troops of violating the truce overnight.
