President Donald Trump ratcheted up the pressure on Iran on Saturday, threatening that the United States could charge toll fees to ships passing through the Strait of Hormuz if Tehran doesn't execute a peace deal within 60 days.

"There will be NO TOLLS in the Hormuz Strait for 60 days during the Cease Fire Period, and there will be NO TOLLS after the 60 day period has expired, unless they are imposed by and for the United States of America, should the deal not be completed, for services rendered as the Guardian Angel to the countries of the Middle East for purposes of both past, present, and future reimbursement of costs," Trump wrote on his Truth Social platform.

Trump's comments came as Vice President JD Vance departed the United States for direct and high-stakes talks with Iran in Switzerland.

The Strait of Hormuz -- one of the world's most important transit points for oil cargo -- has become a critical bargaining chip in the ceasefire negotiations as Iran's tensions with the United States and Israel remain high.

Trump’s statement appeared to warn Tehran it won't have the ability to charge ship tolls in any final deal with America.

Iran and the United States have signed a memorandum of understanding that imposes a 60-day ceasefire to give more time to negotiate a formal  peace treaty.
