Hassan Rouhani said, “The world must know that we do not intend to cheat.”
The Iranian leader warned that Iran would have other options, if world powers “one day decide to follow a different path”.
The framework deal signed on Thursday was to see Iran curb nuclear activities in return for relief from sanctions.
Earlier, Israeli Prime Minister, Benjamin Netanyahu, warned that the deal posed a grave danger to the region, his own country in particular.
Mr Netanyahu said that any compressive accord due before June 30 had to include a “clear and unambiguous Iranian recognition of Israel’s right to exist”.
“Israel will not accept an agreement which allows a country that vows to annihilate us to develop nuclear weapons,” Mr Netanyahu asserted.
French Foreign Minister, Laurent Fabius, said, “We are not completely at the end of the road and the end of the road should be in June, adding that nothing is signed until everything is signed, but things are going in the right direction.”
US President, Barack Obama, also said that the framework agreement would make the world a safer place, as it would “cut off every pathway that Iran could take to develop a nuclear weapon”.
