Iran's Foreign Minister Mohammad Javad Zarif said commitments of a country to the international law will not change when its president changes, even if a revolution happens in that country.
“No revolution has happened in the United States, but an election has been held and the new president thinks that he has changed the world”, Zarif told "Radio Tehran" during a live program on Saturday, IRNA reported.
"We have declared that if a government does not abide by its commitments, there is no room for negotiations with it”, Zarif added.
He censured the US for adopting a duplicitous policy towards Iran as regards direct dialogue between the two sides.
Americans are trying to portray themselves as the ones seeking dialogue after US officials dangled the possibility of talks despite reimposing "all sanctions."
Tehran "should try to expose this hypocritical policy," Zarif added.
The US, he said, has thrown the outcome of some two-and-a-half years of negotiations into doubt by withdrawing from the 2015 nuclear deal between Iran and world countries.
Earlier this week, the administration of US President Donald Trump unleashed a second round of sanctions against Iran. The punitive measures targeted 700 individuals, banks, aircraft, ships and companies tied to Iran’s energy and financial industries.
They came months after Washington scrapped the nuclear accord, called the Joint Comprehensive Plan of Action (JCPOA), despite international objections.
The first round of the anti-Iran bans – which had been lifted under the accord – were reimposed in August.
