The "unjust" embargo on Iran will be lifted and economic prosperity will be attained, said Iranian First Vice President Isaac Jhangere.
In statements on the sidelines of performing Eid prayers in Tahran on Saturday, Jhangere said that Iran is facing several problems at the international and internal levels.
He also underlined the need of attaining unity to continue activities and achievements.
Iran and six major world powers have reached a nuclear deal, capping more than a decade of negotiations with an agreement that could transform the Middle East.
Under the deal, sanctions imposed by the United States, European Union and United Nations will be lifted in return for Iran agreeing long-term curbs on a nuclear program that the West has suspected was aimed at creating a nuclear bomb.
