A ceasefire between Thailand and Cambodia appeared shaky but remained in place Tuesday as tensions lingered despite a truce agreement to end deadly border clashes following economic pressure from the U.

Thailand and Cambodia have reaffirmed their shaky ceasefire after days of fighting along their border, as China stepped in to negotiate with the two countries.

Reuters interviewed four people on both sides of the border to piece together the most detailed account of how the truce was achieved, including previously unreported Thai conditions for joining the talks and the extent of Chinese involvement in the process.
