The move will restore U.S. sanctions that were lifted under a 2015 nuclear deal negotiated by the administration of President Barack Obama, and add 300 new designations in Iran's oil, shipping, insurance and banking sectors.
"We are in the war situation", President Hassan Rouhani said in a television address as the sanctions snapped into place.
"We're not simply going to be content with the level of sanctions that existed under (former US President Barack) Obama in 2015", Bolton said in an interview on Fox Business Network, according to a transcript. "I don't think that in the history of America, someone has entered the White House who is so against law and global conventions", he added.
The US side was unmoved.
Turkey is among eight nations granted temporary waivers from sanctions the USA reimposed Monday on Iran's oil sector.
"Treasury's imposition of unprecedented financial pressure on Iran should make clear to the Iranian regime that they will face mounting financial isolation and economic stagnation until they fundamentally change their destabilizing behavior", U.S. Treasury Secretary Steven Mnuchin said in a statement.
Although commentators have suggested that the latest round of sanctions will hurt Iran, Sajjadpour suggested that they would have a limited impact. The Trump administration granted waivers to China and seven other major buyers so they can continue buying some Iranian crude.

"Unfortunately, we were treated dishonorably by both the American and Iranian governments", said Fereshteh Safarnezhad, a 43-year-old teacher, on the streets of Tehran. Japan and South Korea have mutual defense treaties with the USA and have a key part in the North Korea denuclearization initiative.
Rouhani said even without the waivers Iran would still be able to sell its oil, semi-official Tasnim news agency reported.
The three countries combined produced more than 33 million barrels per day (bpd) for the first time in October, meaning they alone meet more than a third of the world's nearly 100 million bpd of crude oil consumption.
