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

Former Cambodian prime minister Hun Sen says Cambodia can survive without relying on Thai oil, and Thailand's measures against his country would lead to self-destruction.

Thailand's Ministry of Foreign Affairs announced Thursday that it will hand a letter of protest to Cambodia's government after a call between the two countries was allegedly leaked by a high-profile Cambodian official.
