Tehran, November 5 (RHC)-- Foreign Minister Mohammad Javad Zarif says Iran gives a response to the United States’ policy of pursuing “economic terrorism” and “blackmail” in a way quite opposite of what U.S. President Donald Trump was led to believe.

Zarif made the remarks in a tweet after Iranian President Hassan Rouhani said the country will start injecting uranium gas into centrifuges at the Fordow enrichment facility on Wednesday, in the fourth step Tehran is taking away from the multinational nuclear deal, officially known as the Joint Comprehensive Plan of Action (JCPOA), in response to Washington's withdrawal.

President Rouhani says Iran will start injecting uranium gas into centrifuges at the Fordow facility on Wednesday, in the fourth step towards scaling back its commitments under the 2015 nuclear deal.

In a speech broadcast live on TV, Rouhani said the Atomic Energy Organization of Iran (AEOI) will be ordered to begin the gas injection process at the Fordow nuclear facility -- where 1,044 centrifuges are installed -- under the supervision of the International Atomic Energy Agency (IAEA).

In his tweet, the top Iranian diplomat emphasized that the country's latest decision to take the fourth step in scaling back its commitments under the agreement has been foreseen in the JCPOA.

He advised the European Union and the three European signatories to the nuclear deal -- Britain, France and Germany -- to abide by their obligations as an easy solution, saying Iran will "reverse course" in that case.
