Thailand’s Prime Minister Paetongtarn Shinawatra has apologized for the political turbulence set off by a leaked recording of her negotiations with Cambodia’s former leader in the two nations' latest border dispute.

Thai Prime Minister Paetongtarn Shinawatra on Thursday apologised after a phone conversation between her and former Cambodian Prime Minster Hun Sen was leaked.
