The U.S. Treasury described the new penalties as, "the toughest U.S. sanctions ever imposed Iran". It added they would, "target critical sectors Iran's economy, such as the energy, shipping and shipbuilding, and financial sectors". It added: "The USA is engaged a campaign of maximum financial pressure the Iranian regime."
Iran's President Hassan Rouhani struck a defiant tone the face the renewed sanctions. He told his government: "We will proudly break the sanctions." Rouhani described the administration President Donald Trump as, "a throwback to the era of Bush junior and a repeat the same statements as 2003". He said: "The era such statements has evolved and the Iranian people have heard these statements hundreds times, and no longer pay attention." The Al Jazeera news agency said the sanctions were a backward step. It wrote: "With one Trump signature, the goodwill that had been built between Iranians and the rest the world crumbled a matter of months."
