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.

Thailand's Foreign Ministry summoned the Cambodian ambassador on Thursday to deliver a protest letter, following a leaked phone call between Prime Minister Paetongtarn Shinawatra and Cambodia's Senate President Hun Sen discussing border issues.
