USA has re-imposed tough economic sanctions on Iran. U.S. Secretary of State warned Iran that it would be subject to "relentless" pressure unless it changes its "revolutionary course". Trump administration reinstated all sanctions that were lifted in 2015 as result of Iranian nuclear deal. Most of sanctions target core parts of Iran's economy. The U.S. Treasury described new penalties as, "the toughest U.S. sanctions ever imposed on Iran". It added they would, "target critical sectors of Iran's economy, such as energy, shipping and shipbuilding, and financial sectors". It added: "The USA is engaged in campaign of maximum financial pressure on Iranian regime."
Iran's President Hassan Rouhani struck defiant tone in the face of renewed sanctions. He told his government: "We will proudly break the sanctions." Rouhani described the administration of President Donald Trump as, " throwback to the era of Bush junior and repeat of the same statements as 2003". He said: "The era of such statements has evolved and Iranian people have heard these statements hundreds of times, and no longer pay attention." Al Jazeera news agency said sanctions were backward step. It wrote: "With one Trump signature, the goodwill that had been built between Iranians and rest of the world crumbled in matter of months."
