According to IMAG official website, they are organizing trade affairs:
4. Iran Oil Show
6. Iran Logistics
Construction, Automotive, Transport and Logistics, and Oil ang Gas sector in Iran is controlled by the terrorist organization IRGC. IMAG is organizing trade affairs in the Islamic Republic of Iran that are circumventing US sanctions and may expose the German event business to American economic penalties due to terrorism. IMAG played a role in organizing the International Manufacturing Technology Show in Chicago last year. IMAG is slated to organize Conexpo CON/AGG, “North America’s largest construction trade show,” which is held every three years at the Las Vegas Convention Center in Nevada. The next Conexpo CON/AGG event is on March 10-14, 2020 in Las Vegas, Nevada. Last year, US ambassador to Germany, Richard Grenell, told the German news agency “dpa” in connection with German companies: “If you are doing business with Iran, you are giving money to the Iranian regime, which spends massive amounts of money on terrorist activities.”
US government officials have stressed over the years that European companies can do business with Iran or the United States but not both countries.
