A South Korean delegation is in North Korea as we speak: at the shuttered Kaesong Industrial Complex to be more precise.
They crossed the border on Tuesday to check out potential sites to set up an inter-Korean liaison office.
However, South Korean officials admit the process is going to take time... and more trips will be needed.
Kim Hyo-sun reports.
The two Koreas have started preparations to renovate the facilities at the inter-Korean Kaesong Industrial Complex located north of the border -- where they've agreed to open up a joint liaison office.
On Tuesday, 17 South Korean officials and civil staff made a trip north to the industrial park and stayed there for a little over 7 hours.
They worked on draining the flooded basement of the inter-Korean interaction and cooperation office.
And with North Korean officials' help, the team also cleaned up and checked the electric network at another building where they are to set up a temporary liaison office.

The two Koreas agreed -- at their summit talks back in April -- to establish a joint liaison office that stations officials from both Seoul and Pyongyang and enables direct and frequent communication.
And at high-level talks held in early June, the location of such joint office was narrowed down to the Kaesong Industrial Complex -- which was jointly operated by both Koreas until it was shut down in February 2016.
This is the second time South Korean officials made a trip to the complex after that decision was made.
The team is to make another day-long visit on Wednesday and continue the prep work for renovating the buildings.
