U.S. President Donald Trump said on Saturday that a new agreement with Iran aimed at preventing Tehran from acquiring a nuclear weapon is expected to be signed on Sunday, the latest sign of progress in diplomatic efforts to end months of conflict between the two countries.

In a post on his Truth Social platform, Trump described the proposed agreement as fundamentally different from the 2015 Joint Comprehensive Plan of Action (JCPOA), the nuclear accord negotiated during the administration of former President Barack Obama.

Trump Criticizes Obama-Era Nuclear Accord

Trump argued that the JCPOA would have enabled Iran to eventually acquire a nuclear weapon, a characterization that supporters of the agreement have long disputed. The U.S. president said the new framework would instead serve as a permanent barrier to Iran obtaining nuclear weapons.

"They no longer want a Nuclear Weapon, nor will they have one, either through purchase, development, or any other form of procurement," Trump wrote.

The president did not provide details of the proposed agreement or explain how its provisions would differ from previous nuclear arrangements.

Strait of Hormuz Reopening Linked to Agreement

Trump also said the Strait of Hormuz, a strategically important waterway through which a significant share of global oil shipments passes, would be reopened to all traffic immediately after the agreement is signed.

The statement comes amid heightened tensions in the region and follows reports that Iran and the United States have been engaged in negotiations aimed at ending months of conflict and reducing the risk of further military escalation.

No Financial Transfers Planned, Trump Says

In his post, Trump said the proposed agreement would not involve any financial payments to Iran by the United States.

He contrasted the prospective deal with the Obama administration's implementation of the JCPOA, referencing past financial settlements between Washington and Tehran. Trump reiterated his longstanding criticism of the 2015 accord, which he withdrew the United States from during his first term in office.

Remarks on Iran's Nuclear Program

The president also addressed Iran's nuclear infrastructure, stating that nuclear material allegedly buried deep underground would eventually be secured and destroyed following the implementation of the agreement.

Trump referenced previous U.S. military operations against Iranian nuclear facilities and praised the role of American B-2 bomber crews. He said any remaining nuclear material would ultimately be neutralized either in Iran or the United States.

The White House did not immediately provide additional details regarding the president's comments or the timeline for any future nuclear dismantlement activities.

Outlook for U.S.-Iran Relations

Trump expressed optimism about future relations between Washington and Tehran, saying he looked forward to working with Iran and other countries across the Middle East.

He also suggested that the diplomatic process could proceed smoothly but warned that the United States retained other options if negotiations failed.

"Hopefully, this process will all work out quickly, easily, and smoothly," Trump wrote. "If it doesn't, we have the ultimate alternative."

Iranian officials had not publicly responded to Trump's comments at the time of publication.
