South Korea’s communication watchdog, the Korea Communications Commission (KCC), said Tuesday it will investigate Apple and Google over potential violations of the country’s in-app payment rule. Local media reports noted that the agency will start this investigation on August 16.

Apart from Apple and Google, the KCC is also investigating SK Group’s homegrown app store called ONE Store. The watchdog said that it had looked into the practices of all three app stores since May 17, and determined that they might have breached the country’s telecommunication act passed last year.
