Senior Iranian officials have rejected US President Donald Trump's offer of talks without preconditions as worthless and "a humiliation" after he acted to reimpose sanctions on Tehran following his withdrawal from a landmark nuclear deal.
Separately, Iranian President Hassan Rouhani said Trump's repudiation of the accord reached in 2015 was "illegal" and Iran would not easily yield to Washington's renewed campaign to strangle Iran's vital oil exports.
The head of Iran's powerful Revolutionary Guards also dismissed Trump's tentative offer of talks, saying the Islamic Republic was "not North Korea".
In May, Trump pulled the US out of the multilateral deal concluded before he took office, denouncing it as one-sided in Iran's favour.
On Monday, he declared that he would be willing to meet Rouhani without preconditions to discuss how to improve relations but Iran's foreign ministry said Trump's offer contradict his sanctions on Iran.
"How can Trump prove to the Iranian nation that his comments of last night reflect a true intention for negotiation and have not been expressed for populist gains?" foreign ministry spokesman Bahram Qasemi was quoted by Fars news agency on Tuesday.
The head of Iran's Strategic Council on Foreign Relations said Tehran also saw no value in Trump's offer of talks.
"Based on our bad experiences in negotiations with America and based on US officials' violation of their commitments, it is natural that we see no value in his proposal," Kamal Kharrazi was quoted by thel Fars news agency.
Moderate Ali Motahari, the parliamentary deputy speaker, said that to negotiate with Trump now "would be a humiliation".
And the interior minister added that Tehran did not trust Washington. "The United States is not trustworthy. How can we trust this country when it withdraws unilaterally from the nuclear deal?" Abdolreza Rahmani Fazli said.
Meanwhile, The head of the Revolutionary Guard, Major General Mohammad Ali Jafari, insisted Iran would not be forced into meeting Trump, as had North Korea.
"Mr Trump! Iran is not North Korea to accept your offer for a meeting," Ali Jafari was quoted by Fars News agency. "Even US presidents after you will not see that day."
Iran's currency had plumbed to new depths on Monday, dropping past 120,000 rials to the US dollar, but Trump's expressed willingness to negotiate sparked a minor recovery on Tuesday.
Iranian Vice-President Eshagh Jahangiri said the government and the central bank would unveil a new economic plan by the end of this week to tackle the US sanctions and the rial's fall.
Videos on social media showed hundreds of people rallying in Isfahan in central Iran, and Karaj near Tehran, in protest at high prices caused in part by the rial's devaluation under heightened US pressure.
