"Since long ago, Bolton has been a very aggressive and warlike person and has not achieved any of his goals since taking office", said Vaezi.
The Iranian envoy said any meeting must also be held in the framework of the group of major powers that negotiated the 2015 nuclear deal.
"As long as the U.S. government's economic terrorism and such cruel sanctions are imposed on the Iranian people, there is no room for negotiations", the Iranian envoy said, adding that any meeting must be held within the framework of the group of major powers that negotiated the 2015 nuclear deal.
Bolton offered a different version, saying he had submitted his resignation a day before.
"Americans have to realize that warmongering and warmongers are not to their benefit", Rouhani said in a televised address on Wednesday. "Warmongers should be dismissed and the policy of maximum pressure should be set aside".
Britain, France and Germany have been trying to save the nuclear deal and de-escalate tensions between Iran and the United States.
"From the perspective of Iran's government, parliament and people, with the sanctions still in place, negotiations with America have no meaning", Rouhani said in a phone call with his French counterpart Emmanuel Macron, Reuters reported.
Opinions vary on what Bolton's departure will mean for US policy toward Iran.
Though he stressed the dismissal was an internal USA issue, Rabiei called Bolton "the symbol of America's hawkish policies and its animosity toward Iran".
On Twitter, Iranian government spokesman Ali Rabiei called Bolton the administration's "biggest proponent of war & economic terrorism".
Zarif said "the world - minus 3 or 2 panicked cohorts - was breathing a sigh of relief" after Bolton's ouster.
"The enemy imposed "maximum pressure" on us".
Ali Shamkhani, a top Iranian security official and secretary of the Supreme National Security Council, said Bolton's exit has "no impact" on how Tehran views US policy.
While it is no secret the two men had not seen eye to eye on a number of key foreign policy issues, the timing of Bolton's exit is more specifically linked to his pushback against Trump signaling his willingness to ease sanctions on Iran as a way to secure a meeting with President Hassan Rouhani, Bloomberg said.
Toossi added that Bolton's firing was a "good sign", but a change in personnel would be meaningless without a change in policy to go along with it.
Iran's Foreign Minister Mohammed Javad Zarif made similar calls for a USA policy U-turn, tweeting on Wednesday that Washington's "thirst for war" should end with the departure of its "warmonger-in-chief" Bolton.
Iran has rejected talks unless sanctions are lifted first.
