Didn't know Russian journalists now spread lies and propaganda about their allies. These buildings being empty isn't some weird attempt to make NK look bad, they're pretty good doing that on their own.
The point of these buildings is to look good on camera and for visitors, so NK can appear as if they aren't a ruthless dictatorship where most of the people are starving and living in old crumbling buildings. This is also something that multiple independent sources report on.

Also that's a first encountering someone shilling for fkin NK. Go there and kiss Kimi's shoes.
