The U.S. Treasury Department's website reported that "the United States imposed sanctions today, Friday, on four companies based in Iran and Hong Kong for providing materials and technological tools for Iran's ballistic missile and drone programs." The department added that it also imposed sanctions on a company based in Hong Kong for selling Iranian raw materials, in addition to imposing sanctions on six officials in the Cyber Command of the Iranian Revolutionary Guard Corps due to harmful electronic activities targeting critical infrastructure in the United States and elsewhere. Under these sanctions, authorities will prohibit access to all property of the sanctioned entities and individuals located in the United States or under U.S. control. Generally, Americans and U.S. companies are prohibited from conducting any transactions involving the properties of sanctioned individuals.
