According to Choson Exchange:
In 2010, the DPRK revised the laws governing Rason Special Economic Zone.
This booklet, scanned into pdf form, sketches out the new laws in both Korean and English (English is in the back half). It was at this time that the authorities removed Rason from provincial administration, giving it more autonomy in some ways, while also giving authorities in Pyongyang a more direct link to planning for the SEZ.
Potentially interesting clauses include:
- Ships regardless of nationality are permitted to port (article 26)
- Business licenses can be revoked if DPRK law is “seriously” violated. (article 15)
- Prices will be set between the buyer and seller, though some basic consumer goods may be fixed by the local government. (article 26)
- Disputes may be resolved by arbitration either in the DPRK or a 3rd country. (article 45)
