Iran's Supreme Leader Ayatollah Ali Khamenei said Monday that the Iranian people have not seen any benefit from the nuclear deal with world powers, state media reported.
The report quoted Khamenei saying: "Weren't the supposed sanctions lifted to change the life of the people? Is any tangible effect seen in people's life after six months?''
He said the sanctions were supposed to be lifted swiftly. "But now the issue of a gradual lifting of the sanctions has been raised,'' he said. "Why?''
Khamenei, who has final say on all state matters, said the U.S. has continued to thwart Iran's economic relations with other countries despite the landmark accord. He said Tehran will refuse to engage in any further talks with Washington due to what he described as U.S. violations of the deal, though he has previously ruled out further negotiations in other speeches.
"They tell us `Let's talk about regional issues, too.' But the experience of the nuclear deal suggests this is deadly poison and in no way can the Americans be trusted,'' Khamenei was quoted as saying. "Negotiation with such a government means diversion from the correct path of advancement of the country, giving constant concessions and allowing a bullying policy in practice.''
The deal, which went into effect in January, limited Iran's nuclear program in return for lifting some sanctions.
Iran has repeatedly complained that it has fulfilled its end of the deal while all the agreed-upon sanctions have not yet been lifted. Tehran is still struggling to attract large-scale foreign investment and many multinational companies remain fearful of U.S. prosecution or fines for doing business with Iran. The U.S. government still maintains some of its own sanctions against doing business with Iran that are outside the scope of last year's deal.
The U.S.-based company Boeing Co. signed a deal with Tehran involving dozens of planes and worth as much as $25 billion. But the agreement has been criticized by both republican and democratic politicians. In July the U.S. House of Representatives passed two measures that would block the sale, but the issue has not yet reached the senate.
