His statement comes as USA sanctions on the country are set to take effect Tuesday. Some of the sanctions took effect overnight, with others taking effect in November, and President Trump tweeted about them early this morning.
The official said the United States expects Iran will blame it for any new hardships, saying, "They've been doing it for nearly 40 years. I am asking for WORLD PEACE, nothing less", he added.
The sanctions reimposed on Tuesday - targeting access to USA banknotes and key industries such as cars and carpets - were unlikely to cause immediate economic turmoil.
Iran's Foreign Minister Mohammad Javad Zarif told reporters the global reaction to Mr Trump's move showed that the USA was diplomatically "isolated", but acknowledged the sanctions "may cause some disruption".
Other suspended sanctions that will be reimposed on November 4 will target the energy, shipping and insurance sectors, and the central bank of Iran.
The deal, negotiated during the presidency of Barack Obama, saw Iran limit its controversial nuclear activities in exchange for sanctions relief.
He blasted the agreement yet again Monday, calling it a "horrible, one-sided deal (that) failed to achieve the fundamental objective of blocking all paths to an Iranian nuclear bomb".
Despite days of protests and strikes across the country, there appeared to be less unrest as sanctions returned Tuesday - although that said little about the depth of despair, particularly among poorer sections of society.
China appeals for USA calm after new tariff threat
Geng said China's door to dialogue on the trade dispute is open, but that it had to be based on mutual respect and equality. Beijing retaliated with matching tariffs on the same amount of us exports to China.
A European Commission spokeswoman on Monday (6 August) told reporters in Brussels that EU firms are banned from following United States demands to cut business ties with Iran, unless specifically authorised to do so.
Iranians are already seeing the effects of the sanctions, with Iran´s rial currency losing around half its value since Trump announced the U.S. would withdraw from the 2015 nuclear accord.
The commission says this is created to protect European Union firms in Iran by allowing them to recover any United States damages, including legal costs.
The stiff economic sanctions ratchet up pressure on the Islamic Republic despite statements of deep dismay from European allies.
The ministers said the Iran deal is "crucial for the security of Europe, the region and the entire world", and the European Union issued a "blocking statute" on Monday to protect European businesses from the impact of the sanctions.
The European Union´s diplomatic chief Federica Mogherini said the bloc, as well as Britain, France and Germany, deeply regretted Washington´s move.
Many large European firms are leaving Iran for fear of U.S. penalties, and Mr Trump warned of "severe consequences" against firms and individuals that continued to do business with Iran.
"Prices have been increasing for three or four months and everything we need has become so expensive, even before sanctions returned", said Yasaman, a 31-year-old photographer in Tehran.
"There will be pressure because of sanctions, but we will overcome this with unity".
