The North and South Korean militaries have attempted to engage in "operational arms control” at a preliminary level going beyond the stage of merely building mutual trust, South Korean senior officials said on Thursday at the Seoul Defense Dialogue.

Seoul and Pyongyang have had “concrete consultations” on the issue of “prohibiting all hostile acts against each other by land, air, and sea to fundamentally eliminate risk factors of war," Director of presidential National Security Office Chung Eui-yong said.
