“You will see in the coming days and weeks, we are doubling not only our diplomatic efforts, but also our efforts in the trade sector in order to put real pressure on Iran,” the press service of the State Department Pompeo quotes.

Earlier, Secretary of the Supreme National Security Council of Iran, Ali Shamkhani, said that the American side had twice tried to resume negotiations with the Iranian authorities.

Iranian leader Hassan Rouhani said that Iran will not yield to the economic and psychological pressure that the United States is trying to exert on him.
