President Donald Trump says a landmark agreement with Iran is set to be signed on Friday, expressing confidence that the deal will restore stability to the region and reopen a key global energy route.

The announcement follows months of heightened tensions that began when Trump declared the start of “major combat operations” against Iran on February 28. The joint U.S.-Israeli campaign targeted a range of Iranian military, government and infrastructure facilities.

Although a two-week ceasefire was later established, initial negotiations between Washington and Tehran held in Pakistan in April failed to produce a peace agreement. Trump subsequently extended the ceasefire indefinitely while maintaining a U.S. blockade, saying it would remain in place until a final settlement was reached.

Now, the president says a breakthrough has been achieved.

In a message posted on his social media platform, Trump described the agreement as a “great deal” that would bring “peace and security” to the region.

He also said the signing of the accord would pave the way for the reopening of the Strait of Hormuz, one of the world’s most strategically important oil shipping lanes.

“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 wrote.

According to the president, the resumption of maritime traffic through the waterway will be linked to efforts to remove mines and restore safe navigation.

The Strait of Hormuz is a critical route for global energy supplies, carrying a significant portion of the world’s oil exports. Any disruption to shipping through the narrow passage has the potential to affect international energy markets and global trade.

Further details of the agreement and its implementation are expected to emerge following the planned signing ceremony on Friday.
