President Park Geun-hye renewed her calls Tuesday for a peaceful unification between South and North Korea.
  

"Now, it's time to move toward a peaceful unification ... by ending the pain of the division," Park said in a video message to a forum on North Korean affairs.
  

The Korean Peninsula was divided into the capitalistic South and communist North after its liberation from Japan's 1910-45 colonial rule. The two sides fought in the 1950-53 Korean War, which ended in a truce, not a peace treaty.
  

She also stressed South Korea's efforts to build a peace park inside the 4-kilometer-wide Demilitarized Zone that separates the two Koreas.
  

The buffer zone is a 259-kilometer strip of rugged no-man's land stretching from coast to coast, strewn with land mines and barbed wire.
  

North Korea has publicly rejected the project. (Yonhap)
