FILE - In this April 27, 2013 file photo, South Korean vehicles, overloaded with finished products, arrive back from North Korea's Kaesong industrial complex at the customs, immigration and quarantine office near the border village of Panmunjom in Paju, South Korea. Pyongyang has also taken an economic hit for its stance. Operations at the Kaesong factory park - a joint endeavor with South Korea just north of the Demilitarized Zone - have been suspended since early April, when the North barred South Korean factory managers and supply trucks from entering and withdrew all its 53,000 workers.
