According to the Report, this is stated in a statement from the White House.
"Special Envoy Witkoff stressed in a conversation with Minister Araghchi that he has instructions from the President [of the United States Donald] To resolve the differences between our two countries through dialogue and diplomacy, if possible. These issues are very complex, and today's direct communication between Special Envoy Yakov was a step forward in achieving a mutually beneficial result," the document says.
It should be noted that negotiations between the delegations of Iran and the United States took place in Muscat today with the mediation of Oman. The parties discussed easing sanctions against Tehran in exchange for curbing Iran's nuclear program.
