Five months have passed since North Korea blew up the inter-Korean joint liaison office this summer. Pyongyang has not apologized for the damage — nor promised to pay Seoul back for the $8.6 million it spent on financing and renovating the building before North Korea sent it up in smoke.

But now, South Korea is floating plans to make a new liaison office and a new “trade headquarters” in North Korean territory. On Monday, Seoul’s unification minister, Lee In-young, even named four DPRK border regions where the trade building could be built.
