More than 250 local and 70 foreign companies have reportedly taken part in the event that will run through Thursday. Kish Invex 2017 aims to provide a venue for all financial players, namely banks and credit institutions, insurance companies, project leaders and investors in capital, energy, mining, tourism and housing projects of both public and private sectors, to pursue their targets in a professional environment. The expo is often marked by higher-than-usual presence of foreign companies and representatives, as the Kish Island does not require visas, Financial Tribune reported.
