In comments directed at US officials, Larijani cautioned that "ambiguous and deceitful approaches" would make Iran return to the previous track in enriching uranium.
"The path is definitely open for Iran to do enrichment by itself," Larijani underlined.
He noted that in the past, when the West had refused to give Iran 20-percent enriched uranium for a research reactor in Tehran, the country managed to enrich uranium to 20 percent purity.
Iran and the Group 5+1 (Russia, China, the US, Britain, France and Germany) signed an interim nuclear deal on Tehran’s nuclear program in the Swiss city of Geneva in November 2013.
According to the Joint Plan of Action, Iran stopped enriching uranium beyond 5% and neutralized its stockpile of uranium enriched beyond this point.
On April 2, the two sides reached a framework nuclear agreement in Lausanne, Switzerland, with both sides committed to push for a final deal, entitled the Joint Comprehensive Plan of Action- until the end of June.
