The Ambassador of the Republic of Korea is at a loss as the diplomat of the Embassy of the Republic of Korea has revealed that he has leaked the contents of the talks between the two Koreas.

The former presidential aide, Kang Hyo-sang, said in a recent press conference that he has caught a diplomat K who has leaked the contents of a summit conversation with Kang.

"The current investigation is in progress and we will have action if the outcome comes," a foreign ministry official said.

The contents of the normal telephone conversation correspond to the third grade secret. According to the presidential ordinance 'security business regulations', the secret of the third grade is a secret that may harm national security if it is leaked.

The US embassy has been informed that last week that K has taken "no business" measures.

Ambassador Cho Yoon-jae told the staff of the embassy, ​​"Please do the investigation as it is," and it is said that you should do your best in your position so that there is no disruption in important business proceedings.
