North Korea has threatened to take corresponding measures against South Korea if it joins international efforts to impose sanctions on Pyongyang.

In a statement carried by the North’s Korean Central News Agency Wednesday, the Committee for the Peaceful Reunification of the Fatherland said if the South joins the U.S. ploy in pressuring the North, Pyongyang will consider it an act of confrontation and take corresponding actions.

The statement said that the South’s participation in bearing down on the North would be an overturn of the June 15th joint declaration and a serious provocation, leading to the crisis of war on the Korean Peninsula.

The North’s committee in charge of inter-Korean affairs also said that the South would have to assume all responsibility and pay dearly if international sanctions joined by the South lead to destructive results in inter-Korean relations.

It is the first time for the North to issue a warning on the South's involvement with sanctions since its October ninth nuclear test.
