On Friday, Trump's administration announced that it would waive sanctions on Iran that were required by the JCPOA, also known as the Iran nuclear deal. However, the US leader said it would be the last time he signs the waiver unless the deal is modified. Trump also announced his intention to toughen anti-Iran sanctions over Tehran's ballistic missiles tests.
"During the year, even before his win in the presidential election, during the election campaign, Mr. Trump has taken all possible steps to impede the nuclear deal with Iran. But he failed," Rouhani said in a speech broadcast by state television.
In July 2015, the European Union, Iran and the P5+1 group of nations — the United States, Russia, China, France and the United Kingdom plus Germany — signed the JCPOA. The agreement stipulates a gradual lifting of sanctions imposed on Iran in exchange for Tehran maintaining the peaceful nature of its nuclear program.
