Secretary of Iran’s Expediency Council (EC) Mohsen Rezayee said Tehran should enrich uranium to purity levels above 20% if the talks with the world powers end in failure.

Addressing the annual forum of Iranian Land's Islamic Party in Tehran, Rezayee said Iran is entitled to the right to enrich uranium to purity levels above 20%.

"In think that if the western side pushes the negotiations into failure, Iran shouldn’t limit itself to 20% enrichment and should continue enriching uranium to higher grades to the point that the national interests allow,” the Iranian official said on Friday according to Fars news agency.

He pointed out that a number of countries, including Brazil and Argentina, are now enriching uranium to 80% grade and use it as a good source of income.

Meanwhile, Rezayee advised the western powers, specially the US, to seize the present opportunity for cutting a deal with Iran by accepting Iran's right to use peaceful nuclear technology and removing all sanctions against the country.

He added that Washington's failures in Syria and Ukraine show that the country is no more able to start a new challenge since the US will have to pay a heavy price and lose the region if it stirs a fresh wave of tension in the Middle-East.
