Beginning in 1390H, the Kingdom of Saudi Arabia implemented a plan for the development of industrial cities. Industry is seen as an enduring and fundamental source of national income, and the basic plan is to resettle or establish factories in these cities where all the elements, such as basic services and equipment are available. In addition, where the environmental conditions, safety requirements, employment opportunities for citizens, and distribution of resources are considered in a manner that ensures that each of the Kingdom's regions has a carefully considered balance of each to reduce migration to the main areas.
The first three cities, in 1393H, were established in Riyadh, Jeddah and Dammam on a total area not exceeding 1.4 million square meters. The success of these ventures led to the expansion of the program into the second five-year plan in 1395-1400H. By the end of the seventh plan, 1420-1425H, industrial cities numbered 14, in regions such as Riyadh 1st. and 2nd., Jeddah 1st., Dammam 1st. and 2nd., Makkah, Qassim, Al Ahsa, Madinah, Assir, Al-Jouf, Tabuk, Hail and Najran.
Thereafter, Under the Council of Ministers Resolution No. (235), dated 27/8/1422 H, delegating authority to MODON, the agency sought to meet the growing demands for industrial land and expanded the existing industrial cities in 2009 in the following cities:
1. Dammam 2nd.
3. Riyadh 2nd.
MODON also established and expanded a number of industrial cities during 2009 – 2013:
1. Developed the first phase of Sudair (8 million square meters), whereas work on the 2nd. Phase is ongoing.
2. Developed the first phase of Al-Kharj (5 million square meters), whereas work on the 2nd. Phase is ongoing.
3. Jeddah 2nd. (8 million square meters).
4. Jazan (one million square meters).
5. Ar'ar (one million square meters).
6. Riyadh 3rd.
