Iran claims it will give US talks about nuclear plans a "genuine chance"

"Important and practical" Iranian proposals

Iran had rejected direct negotiations with Washington before Trump announced on March 30: "If they don't make a deal, there will be bombing, and it will be bombing the likes of which they have never seen before."

"Important and practical" Iranian proposals have been prepared in pursuit of "a real and fair" agreement, Ali Shamkhani, an adviser to Iran's Supreme Leader Ayatollah Ali Khamenei, said in a post on social media.

"If Washington comes to the talks with sincere intentions and genuine will to reach an agreement, the path to a deal will be clear and smooth," Shamkhani added.

Since Trump pulled the US out of the 2015 deal that curbed Iran's uranium enrichment activity, deeming the accord deeply flawed, Tehran has accumulated a stockpile of uranium refined to levels close to what would be suitable for nuclear bomb fuel.

Iran had agreed in the deal, reached during US President Barack Obama's administration, to strictly limit its enrichment activity in return for a lifting of global economic sanctions.

Tehran says its programme is purely for peaceful energy purposes, but the West says it goes far beyond any civilian requirements, and suspects Tehran of covertly seeking to develop nuclear weapons capability.
