On May 20, Iran's Supreme Leader Khamenei warned US representatives involved in indirect negotiations to be careful in their words and actions and not to keep talking nonsense. He said that the US statement that it “does not allow Iran to carry out uranium enrichment activities” is absurd, and Iran does not need permission from the United States to carry out its own policies. Iranian Foreign Minister Alagzi also said during an interview on the same day that the US side's position is completely unreasonable and illogical, and uranium enrichment is not an issue that can be negotiated at all. US special envoy for the Middle East, Witkoff, has said several times recently, “Iran is absolutely not allowed to have another uranium enrichment program — this is America's 'red line'. The United States does not allow Iran to carry out any uranium enrichment activities, even to produce enriched uranium with an abundance of only 1%.”
