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.

Amid escalating border disputes between Cambodia and Thailand, the leaked phone conversation ignited national outrage in Thailand, prompting an opposition party to call for Paetongtarn’s resignation and a party within her coalition to quit.

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.
