Speaking at a local gathering on Saturday, he said Iran's nuclear negotiators will break down the sanctions and uphold the country's dignity although some inside the country are using impolite and insulting rhetoric against them.

Despite exporting one million barrel of oil per day, he added, the money is not allowed to enter the country.

'Monetary sources are blocked due to the sanctions. When they are removed, it will bag $100 billion for the country.'

On April 2, Iran and the P5+1 group of world powers issued a joint statement after marathon talks in Lausanne calling, among other things, for the removal of UNSC sanctions against the Islamic Republic.

The statement was read out in a joint press conference in the Swiss city by the EU Foreign Policy Chief Federica Mogherini, and Iran’s Foreign Minister Mohammad Javad Zarif.

Aaccording to the agreement reached between Iran and the six world powers, Zarif said, all the US, EU and UN Security Council sanctions against Iran will be lifted under the deal.

Recent developments in nuclear negotiations signal that the talks for drafting the final nuclear deal is entering a new phase.
