North Korea has been engaging in major deception by offering to dismantle a launching site at the same time it secretly continues to make improvements at 16 hidden bases that would bolster launches of conventional and nuclear warheads, The New York Times reported on Monday.
Previously, there was allotted to soldiers and military equipment.
The two nations technically remain at war after the 1950-53 Korean War that sealed the division of the peninsula and ended with a ceasefire instead of a peace treaty.
Some 70 members of the committee staged a performance in the heart of Seoul on Wednesday and waved pink flowers that resembled those used by Pyongyang citizens to welcome South Korean President Moon Jae-in when he visited the North Korean capital in September for a summit with Kim.
According to defense officials here, North Korea operates about 160 guard posts inside the DMZ along the 250-kilometer-long swath of land.
"The North Korean side had completed the clearance of 636 mines, while our area was completely free of minefields".
But as part of the latest reconciliatory gesture, the two Koreas last month removed all firearms and guard posts from the area, leaving it manned by 35 unarmed personnel from each side. It provides that in the demilitarized buffer zone on each side of the border will be demolished at 10 border posts, one post will remain there.
The operation to remove mines began on October 1 in two border areas - one in Cheorwon and the other in the truce village of Panmunjom. Unless the sanctions are lifted, it would be impossible for Moon to push ahead with his more ambitious plans for engagement, such as reconnecting railways and roads across the border and normalizing operations at a jointly run factory park. "This goes against the agreed global effort for North Korean sanctions".
Analysts say the discord may have caused the last-minute cancellation of a meeting between U.S. Secretary of State Mike Pompeo and his North Korean counterpart, Kim Yong Chol, that had been scheduled for this past Thursday to discuss denuclearization issues and setting up a second summit between Kim Jong Un and President Donald Trump.
