Iran offered its most definitive assessment on Friday that it was close to signing a memorandum of understanding (MOU) with the US, as both countries jostled to frame the deal as a victory.

The signing of the MOU would trigger a 60-day period for "technical" negotiations, according to the Trump administration.

“The Islamabad Memorandum of Understanding has never been closer. Pending its finalization, the media should refrain from entering speculation about its content,” Iranian Foreign Minister Abbas Araghchi wrote in a social media post.

US President Donald Trump shared Aragchi's remarks.

Araghchi’s comments came after Iran’s Mehr news agency said the deal would secure the release of $24bn in frozen Iranian assets and cement Iran’s control of the Strait of Hormuz.
