Iran has warned that it will walk away from any potential nuclear agreement if the United States wants end to its uranium enrichment program. Iranian Foreign Minister Abbas Araqchi made the statement on Thursday.

The two nations are set to resume indirect nuclear talks on May 23 in Rome, marking the fifth round of talks mediated by Oman since April, according to an announcement by Omani Foreign Minister Badr Albusaidi.

In an interview, Iranian Foreign Minister Abbas Araghchi said that Iran will never pause its uranium enrichment program. “I have said it before, and I repeat it again: uranium enrichment in Iran will continue—with or without an agreement.”

In 2018, during his first term, President Trump backed off the United States from the 2015 nuclear agreement reached between Iran and six world powers. The Trump administration then pursued a “maximum pressure” campaign to compel Iran to renegotiate terms for “better” deal. However, that effort did not succeed in bringing Iran back to the negotiating table before the end of his first term.

Now, after reassuming office, Trump is desperately trying to forge a new agreement. He issued warnings to Iran, saying that refusal to engage constructively could result in military consequences.
