The US-Iran negotiations have concluded, and no agreement was reached.

On April 12, according to local time in Iran early morning news, the Iran-US talks ended a few minutes ago, with the US's excessive demands hindering the achievement of a joint framework and agreement, and no deal was reached.
US Vice President Vance stated on the 12th at a press conference held in Islamabad, Pakistan, that the US has not yet reached a consensus with Iran and will return to the United States.
Vance said that the failure to reach an agreement in the US-Iran negotiations mainly stems from Iran not making a clear commitment to abandon its development of nuclear weapons.
The US has clearly outlined its "red lines" and acceptable and unacceptable conditions, while Iran "chose not to accept these terms."
According to Iran's Tasnim News Agency on the 12th, the timing, location, and plan for Iran's next round of negotiations with the US have not yet been announced.
