WASHINGTON/TEHRAN/ISLAMABAD/LONDON - US President Donald Trump said Sunday that the US-Iran peace deal "is now complete" and that the Strait of Hormuz will reopen upon the signing of the deal on Friday.

"The Deal with the Islamic Republic of Iran is now complete," Trump wrote on his Truth Social. "I hereby fully authorize the toll free opening of the Strait of Hormuz, and, simultaneously herewith, authorize the immediate removal of the United States Naval blockade."

"Ships of the World, start your engines. Let the oil flow!" said Trump.

He said in another post a few minutes later that the strait will reopen upon the signing of the deal on Friday.

"With the opening of the Strait upon the signing of the Deal on Friday, for purposes of mine removal, oil will flow on both ends again for the Region, and the World!" Trump said.

In Tehran, Iranian Deputy Foreign Minister for Legal and International Affairs Kazem Gharibabadi said early Monday that the US naval blockade against Iran will be lifted as of tonight and the immediate and permanent end of the war and military operations on all fronts, including Lebanon, is announced.

Gharibabadi said Iran and the United States will sign the finalized draft of a peace memorandum of understanding (MoU) in Switzerland on June 19, according to Iran's semi-official Tasnim news agency.

Tasnim also cited a source as saying that the Strait of Hormuz will reopen following the signing ceremony in Switzerland.

Trump told The Wall Street Journal that the agreement would be signed electronically by him or by Vice-President JD Vance in person.

Vance told Fox News on Sunday evening that he plans to attend the official signing ceremony, though Trump may attend himself.

"I think we're still figuring out the logistics on who's going to attend that signing ceremony," Vance said. "I certainly plan to be there, but it's possible the President himself could be there."

Trump is scheduled to attend the annual summit of the Group of Seven nations in France.

The deal would include a commitment from Iran not to obtain nuclear weapons and an immediate reopening of the Strait of Hormuz, Trump told The Wall Street Journal.

He also expressed no urgency to extract nuclear material from Iran, saying "there's no rush."

"We'll get the nuclear dust later on when we're ready to go in and do it. I'd say over the next month or two, there's no rush," he said.

There would be strong nuclear inspections on the Iranians, Trump said, without specifying how they would work.

Under the deal, Iran wouldn't be provided cash but sanctions could potentially be lifted, Trump added.

"We'll see how they behave," he said.

Trump also claimed Israeli Prime Minister Benjamin Netanyahu was supportive of the deal.

"Bibi is OK with it," Trump was quoted. "Why is it good for Bibi? Iran cannot have a nuclear weapon under any circumstance."

Iran's state-run IRIB TV, qouting Gharibabadi, said Iran's entry into a 60-day period of negotiations with the United States on its nuclear program and the removal of sanctions will hinge on the US fulfillment of its preliminary commitments, which will be verified by Tehran from now until the signing ceremony.

Pre-implementation discussions 

Pakistani Prime Minister Shehbaz Sharif said mediators will facilitate a series of meetings this week aimed at preparing for the implementation of the agreement.

Sharif said these pre-implementation discussions will lay the foundation for the technical talks and the official signing ceremony.

The prime minister thanked the United States and Iran for their commitment to a diplomatic resolution of the conflict and expressed appreciation for the role played by regional partners in the mediation process.

UN Secretary-General Antonio Guterres welcomes the deal, and hopes that the parties will build on this new momentum and redouble their efforts toward a final resolution of the conflict, his spokesperson said Sunday.

The United States and Israel launched massive attacks against Iran on Feb 28, killing Iran's then Supreme Leader Ali Khamenei and triggering a regional conflict that has reshaped the Middle East's security landscape. The conflict has since claimed thousands of lives and disrupted global energy markets.

Britain, France, Germany and Italy ready to lift sanctions

Meanwhile, the leaders of Britain, France, Germany and Italy welcomed the US-Iran peace deal announced on Sunday in a joint statement.

"This is a moment of opportunity to restore regional stability and stabilize the global economy," BBC quoted the statement as saying.

While noting that Iran "must never acquire a nuclear weapon," the major European countries said they are "prepared to lift relevant sanctions in response to clear, verifiable steps by Iran on its nuclear program."

The European leaders urged the US-Iran deal to be "implemented rapidly and comprehensively," saying the "urgent reopening of the Strait of Hormuz with unconditional and unrestricted freedom of navigation is essential."

"We will work intensively with the US, Iran and regional partners to seize this moment, maintain momentum and achieve a long-term diplomatic settlement," the statement added.
