The attraction of foreign financial resources to develop investment has been among the major objectives of the Government, in particular after the JCPOA. The relevance of this issue can be seen in the Sixth Development Plan Act, where a significant portion of the financial sources for investment is targeted to be funded through foreign capital. The realization of the average annual 8% growth rate in the Sixth Development Plan depends on attracting foreign investment.

Having reviewed such regulatory issues, the paper investigated the status of foreign financial resources inflow based on the available statistics and information.
