Iranian Foreign Minister Abbas Araqchi said on Sunday that the 2015 nuclear agreement in its current form is not viable, stressing, "Our nuclear situation has made significant progress."

Iranian media quoted Araghchi as saying: "Our current tactic and approach is to conduct indirect negotiations with the United States."

Araghchi affirmed that Iran's nuclear program is "completely peaceful," adding, "We are confident of that, and we are prepared to reinforce this confidence with others."

He added, "Our priority is to neutralize the sanctions that the enemy uses against us to achieve its goals," noting that Tehran has always avoided war and has not sought it, stressing, "But we are prepared for it and are not afraid of it."

This month, Tehran received an official letter from US President Donald Trump regarding the nuclear agreement. However, Iranian Supreme Leader Ali Khamenei has consistently rejected negotiations, speaking of the futility of sitting down to a dialogue with "the person who tore up the 2015 nuclear agreement."

Anwar Gargash, diplomatic advisor to the UAE president, delivered the letter to Iranian Foreign Minister Abbas Araghchi in Tehran. Days earlier, Trump said he had sent a letter to Khamenei proposing talks on the nuclear deal, giving Tehran a choice between a military option and an agreement that would prevent it from possessing nuclear weapons.
