"Iran is among the safest countries for (foreign) investment," Tayyebnia told reporters on the sidelines of a meeting with Iranian economic activists.
He underlined that the Iranian economy is growing, and advised investors to "begin investing in the production and economic sectors" of Iran.
Last week, an Iranian official said the country plans to attract more domestic and foreign investors.
"Foreign investment would help us meet financial needs, transfer technology, increase tax revenue, boost exports and production and be able to create more jobs," Head of Iran's Organization for Investment and Economic and Technical Assistance Mohammad Khazayee said.
Khazayee said that supporting domestic investors is also important as they implement infrastructural and fundamental projects which are the significant advantages of a country to attract more international investment.
Iran, on many occasions, has underlined that it has paved the way for attracting more investments in its ports, free trade zones, and development projects.
Meantime, so many foreign countries and international companies have voiced their enthusiasm for investing in the country's projects.
