SEOUL - North Korea rejected on Friday a South Korean proposal for talks aimed at restarting a joint factory zone saying the South has acted in an "unpardonable" manner to jeopardize a "precious" legacy of the rivals' bid to seek peace.
The North's National Defense Commission, its supreme leadership body, repeated that what it saw as the reckless behavior of the South had thrown into question the safety of the zone's operation and had forced it to stop access there.
The Kaesong industrial zone is just inside North Korea.
"If the South's puppet regime turns a blind eye to reality and continues to pursue a worsening of the situation, we will be forced to take a final and decisive important measure," a spokesman for the commission was quoted as saying.
The Kaesong industrial zone opened in 2004 as part of a so-called sunshine policy of engagement and optimism between the two Koreas, still technically at war after their 1950-53 war conflict ended in a truce, not a treaty.
