I wouldn't be issuing political risk insurance to anyone with respect to the DPRK these days, that's for sure. There is clearly an effort to reform the system underway, but it's unclear who is behind it and who is opposing it (not that the West should necessarily care that much; either the country collapses or it doesn't, and we should have a contingency plan prepared regardless). Obviously, attempts at reform in a nation like North Korea destabilize the already shaky system they've had in place for a while by reapportioning economic power. If it works it will start to look like China. If it fails the wheels will probably come off in the next few months, probably by Christmas/New Year's.
