Abu Dhabi, United Arab Emirates - U.S. President Donald Trump said Friday that Iran has made a recommendation on its rapidly moving nuclear plan as negotiations continue.

Trump's remarks represent his first acknowledgement of the U.S. proposal was made with Tehran after multiple rounds of negotiations between U.S. Middle East envoy Steve Witkov and Iranian Foreign Secretary Abbas Aragic.

Negotiations have reached the "expert" level - which means both parties are trying to see if they can reach any agreement on the details of any possible deal. However, one major point remains Iran’s abundance of uranium, which Tehran insists must be allowed, while the Trump administration is increasingly insisting that the Islamic Republic must give up.

Trump commented on Air Force One as he ended his trip to the United Arab Emirates, his last stop in his trip to the Three Kingdoms in the Middle East, which also includes Saudi Arabia and Qatar.

In almost all the events he attended in the region, he insisted that Iran could not be allowed to obtain nuclear bombs - U.S. intelligence agencies assess that Tehran is not actively pursuing Iran, although its plans are being able to be weaponized.

A reporter asked Trump: "Did the United States give them a formal proposal in Iran? Did Steve Vitokov hand it over to?"

"They have a suggestion," Trump replied. "But the most important thing is that they know they have to move quickly or something bad will happen."

Trump did not elaborate on the essence of the proposal, nor did Iran immediately admit to owning the proposal. Araghchi spoke with reporters at the Tehran International Expo on Thursday and said Iran has not yet made any American proposals.

Araghchi also criticized his alleged ambivalence and inconsistent statements, calling them signs of chaos in Washington or calculated negotiation strategies. Witkoff once suggested that Iran could enrich uranium at a concentration of 3.67%, and then began saying that all Iranian abundance must stop.

“We heard a lot of contradictory remarks from the United States, Washington, the president and the new administration,” Aragic said. “Sometimes we hear two or three different positions a day.”

Iranian and U.S. officials have been negotiating in Oman and Rome, always mediated by Oman Foreign Minister Badr al-Busaidi, a trusted interlocutor between the two countries. The negotiations were intended to limit Iran's nuclear program in exchange for some broken economic sanctions imposed by the United States on the Islamic Republic and ended in a half-century of hatred.

If a deal is not reached, Trump has repeatedly threatened to release air strikes against Iran. Iranian officials are increasingly warning that they can use uranium to store to near-weapon-level levels in pursuit of nuclear weapons. Meanwhile, Israel threatened to threaten Iran's nuclear facilities, which has caused the Israel-Hamas war in the Gaza Strip to scream, which would cause Iran's nuclear facilities to attack on its own.
