There is no reason to believe that this measure will have a different fate. Some North Korean watchers go so far as to say that this order can't be actually implemented, because it is practically impossible to stop the use of foreign currency in North Korean market. At the wholesale level, virtually all transactions are done in either dollars or yuan. If the regime does try to enforce this order, North Korean commerce (what little there is) would be completely paralyzed.
The more Kim Jong-Un tries to strengthen his grip over his country, the more quickly it will slip away. The total loss of control won't be long.
