[The United States imposes a new round of sanctions on Iran] On October 22, the US Treasury Department website showed that the United States has imposed a new round of sanctions on Iran. The U.S. Treasury Department issued a statement saying that as part of "economic isolation actions," the U.S. Treasury Department imposed sanctions on law firms headquartered in Panama and Greece. The statement stated that the law firm has supported Iran's illegal shipping activities for many years, indirectly helping Tehran to obtain revenue and "funding Iran's military, weapons and nuclear programs." The statement pointed out that the U.S. Treasury Department also sanctioned shipping agencies headquartered in Singapore and the United Arab Emirates that day, saying that these agencies directly assisted the operation of Iran’s “shadow fleet.” The statement said that the operation that day also targeted a group of cargo ships that generate revenue for Iran.
