The US President wrote about this in Truth Social, although the Iranian Foreign Ministry reported that his negotiating team is not planning a trip to Pakistan or Geneva in the next few days.

Trump said Iran "no longer wants nuclear weapons and will not have them, whether through purchase, development, or any other form of acquisition," and that "no money will be transferred."

He stated that US forces will remove enriched uranium buried at Iranian nuclear facilities "at an appropriate time when things are calm."

Iran's Islamic Revolutionary Guard Corps, in a Telegram post, said Trump's insistence on a Sunday signing is a "test for the negotiating team," noting that Iranian negotiators have clearly stated that an agreement has not yet been finalized and "definitely will not be reached on Sunday." Iranian Foreign Ministry spokesman Esmail Baghaei said the Islamabad Memorandum will not be signed on Sunday, citing the other side's indecision, although a signing in the coming days is not ruled out.

He said the memorandum is not a final agreement, but rather a preliminary understanding aimed at ending the war and does not address the nuclear issue.

Baghaei also stated that foreign military bases and presence in the region must cease, and that Iran will charge fees for services provided in the Strait of Hormuz, the Fars News Agency reported.

Pakistan Foreign Minister Ishaq Dar told Saudi Foreign Minister Prince Faisal bin Farhan in a phone call that the US and Iran are expected to sign the agreement remotely on Sunday, the Pakistani Foreign Ministry reported on X (formerly Twitter, blocked in Russia).

Both sides welcomed the entry of US-Iran talks into their "final phase" and discussed the upcoming meeting of the Regional Quartet foreign ministers scheduled in Egypt later this month.

Iran's top security envoy, Gharibabadi, met with the Russian and Chinese ambassadors in Tehran on Saturday to discuss "the latest developments regarding the draft memorandum of understanding in Islamabad," declaring that "the strategic partnership between Iran, China, and Russia will continue in full force."

Abbas Araghchi said both sides agreed to "respect each other's sovereignty," which he called the first such clear written commitment from the US in 47 years. Vice President J.D. Vance stated that "the Iranians are not receiving any cash, and no funds will be unfrozen simply for signing the agreement." British Prime Minister Keir Starmer spoke with Trump on Saturday, expressing support for US efforts to end the conflict with Iran and emphasizing the need for a lasting peace agreement. The two leaders agreed to restore freedom of navigation and plan to discuss the issue in more detail at the G7 summit next week.
