South Korea has taken a number of steps to each tension with their neighbour, North Korea, ahead of top-level talks later this week.
One such step was that South Korean authorities had stopped broadcasting propaganda via loudspeakers along the border.
The South has dozens of loudspeakers along the border area, which blast everything from K-pop music to critical news reports of the North.
The broadcasts can be heard by the North's troops stationed along the border and civilians in the area.
It is not known if North Korea will shut its own loudspeakers off.
They usually play reports that are critical of Seoul and its allies.
South Korea's move was aimed at "reducing military tensions between the South and North and creating the mood of peaceful talks", the Ministry of National Defense said in a statement to the Yonhap news agency.
