South and North Korea engaged in detailed negotiations Wednesday on ways to reform management rules of the suspended joint industrial park in the communist country, protect investments and strive for ways to internationalize the complex. The two sub-committee meetings that began in North Korea at 10 a.m. come after both sides agreed on Aug. 14 to reopen the Kaesong Industrial Complex in the North, and inked a deal last Thursday to create a new joint management committee. The joint committee, co-chaired by officials representing Seoul and Pyongyang, is made up of four sub-committees, and will receive administrative assistance from a permanent secretariat. The committee will be in charge of running the industrial complex, which remains the main economic link between the two countries, just north of the demilitarized zone (DMZ).
