Pyongyang's state-controlled news agency KCNA said Thursday North Korea's foreign ministry, military and "peace research institute" condemns Seoul for anti-state activities.
The North Korean government agencies have issued a "research paper" titled "The truth about the underhanded anti-North Korea plot of the South Korea puppet authorities overseas," the statement read.
"The South Korean puppets who are on the defensive are trying to hang on, in their political and military confrontation with us, with a dirty psychological plot in order to evade being pushed into a corner," KCNA said.
A statement from the Pyongyang peace institute added the "South Korea puppets, in their anti-North Korea scheme, are focused on inciting defections."
North Korea also said Seoul's anti-Pyongyang policy reached its climax when South Korean President Park Geun-hye urged North Koreans to leave their society for the "bosom of freedom" in the South on Armed Forces Day in October.
At the time, North Korea had called Park's speech a "provocation."
On Thursday, North Korea claimed Seoul's intelligence service delivered unsolicited mail and email to North Korean diplomats and trade representatives, encouraging them to leave.
"The South Korean puppet authorities have created an anti-humanitarian situation by inducing defections, which has given rise to the kidnapping of our women workers," the statement read, referring to the defection of 12 North Korean waitresses and their manager in April.
