 The first Rason SEZ Law launched in 1993 contained chapters of Fundamentals, Duties and Rights of Operation Committee, Guarantee of Economy Activities, Customs Duties, Currency and Finance, Guarantee and Preferential Treatment and Settlement of Disputes.The basic framework was continued until 2011, when it made modifications on Development and Management of the Zone, Establishment of Enterprises, Economic and Trade Activities and Incentives and Preferential Treatment, providing more details of the environment for foreign-invested companies.However it still did not cover all basically required details for foreign-invest companies such as regulations of labor, tax, or financial management.
