Cambodia on Friday welcomed the return of two wounded soldiers who had been captured by the Thai army after the two sides had already implemented a ceasefire to end five days of combat over competing territorial claims.

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

The ceasefire reached in Malaysia was supposed to take effect at midnight on Monday, but it was quickly tested as Thailand and Cambodia continued to accuse each other of violating the truce agreements.
