The Republic of Korea and the Democratic People's Republic of Korea are waging a war of words less than two weeks after the two sides reached an agreement to defuse tensions over land mine blasts and the broadcasting of propaganda messages.

ROK Unification Ministry spokesman Jeong Joon-hee told a news briefing on Friday that it was regrettable for the DPRK to denounce what ROK President Park Geun-hye said during her visit to China and threaten the failure to carry out what was agreed upon during the high-level inter-Korean dialogue.

His comments came a day after the DPRK's Committee for the Peaceful Reunification of Korea condemned Park for her "impertinent" remarks.
