I don’t know what fairy tale stories e you’re imagining but N.Korean worker brigade camps In Russia are well guarded by N.Korean guards.....no different than when they work in N.Korea. They cannot leave the camps and are just as afraid of messing up as they are in N.Korea. .....they get no income of their own it goes to Fat Boy and they have no choice to go and why its called ‘Forced labor”...........mcDonalds’ and Pop music...you’ve got to be kidding !
They are working on things like the World Cup stadiums so its not out of the question to be exposed to things inadverdently. And I just wrote that I met a tourist who was able to converse with a group of them on a train. Better than nothing.
