Seoul is disappointed by North Korean leader Kim Yo-jeong's "vulgar language" to President Yoon Seok-yeol and his government as she called the South Korean leader and his administration "idiots," Yonhap News Agency reported.

“I wonder what ‘sanctions’ the South Korean group, no more than a running wild dog gnawing on a bone given by the U.S., impudently will impose on North Korea,” Kim Yo Jong said in a statement carried by state media. “What a spectacle sight!”

Earlier, the sister of North Korean leader Kim Jong-un, deputy head of the Central Committee of the Workers' Party of Korea Kim Yo-jong, speaking about possible sanctions from Seoul, said that South Korean President Yoon Seok-yeol and his government were "idiots".
