The new economic city is expected to attract more than SR100bn in investment and create some 500,000 new jobs.

The aluminum complex under construction at Jazan Economic City (JEC) expects to create 12,000 new jobs. One of JEC's anchor investments, the aluminum complex is the largest mineral processing facility to be built in JEC's industrial zone and led by Saudi-based Western Way for Industrial Development Co (WWIDC). The plant, when completed, targets production of 1.4mn tons of alumina and 660,000-700,000 ton aluminum per annum. All the alumina will be made from bauxite imported from Greece. Total investment in the complex as well as in the associated plants required to supply adequate power, is estimated at US$4bn.
