Versailles, France, June 18, 2026 — U.S. President Donald Trump and Iranian President Masoud Pezeshkian have formally signed a historic memorandum of understanding (MoU) aimed at ending hostilities between the United States and Iran, reopening the Strait of Hormuz, and laying the foundation for a broader regional peace process.
The agreement was signed Wednesday evening at the historic Palace of Versailles following a dinner hosted by French President Emmanuel Macron. Speaking briefly to reporters after the ceremony, Trump confirmed the signing, saying simply, “It’s signed.”
The 14-point agreement, signed in both English and Farsi, commits Iran to refrain from procuring or developing nuclear weapons while requiring the United States to ease sanctions and facilitate Iran’s return to international oil markets. The deal also outlines steps for reopening the strategically vital Strait of Hormuz, through which a significant share of the world's energy supplies passes.
According to the memorandum, Washington will issue waivers allowing Iran to resume oil exports and regain access to parts of the international banking system. The agreement further establishes a proposed $300 billion reconstruction fund for Iran, to be developed in future negotiations with support from the United States and regional partners.
Images released by Iranian state media showed President Pezeshkian signing the document in Tehran after receiving a copy bearing Trump’s signature. Iranian officials said the bilingual text was prepared to ensure complete transparency and prevent disputes over interpretation.
The accord is expected to take effect immediately. Pakistan, which played a central mediation role alongside Qatar during negotiations, welcomed the breakthrough. Pakistani Prime Minister Shehbaz Sharif said the agreement would lead to the immediate reopening of the Strait of Hormuz and the lifting of the U.S. naval blockade.
The deal also seeks to end conflict across multiple fronts in the region, including Lebanon, where Israeli military operations have continued despite broader diplomatic efforts. Supporters of the agreement argue that reducing tensions could stabilize energy markets and lower global oil prices.
International reaction was largely positive. Chinese Foreign Minister Wang Yi described the agreement as evidence that “the dawn of peace has arrived,” urging all parties to honor their commitments and maintain stability in the Gulf region.
Despite the optimism, questions remain about implementation. Iranian Parliament Speaker Mohammad Bagher Ghalibaf cautioned that Tehran would not uphold its obligations if Washington failed to fulfill its own promises under the agreement.
The signing ceremony carried historical symbolism. The memorandum was signed at the same Palace of Versailles where U.S. President Woodrow Wilson signed the Treaty of Versailles in 1919, ending World War I. Historians have often cited that treaty as a key factor in shaping the political tensions that eventually contributed to World War II.
While supporters hail the new accord as a diplomatic breakthrough, critics in Washington remain divided. Some lawmakers praised the agreement as a path toward regional stability, while others argued it grants excessive concessions to Tehran.
For now, the signing marks one of the most significant diplomatic developments in the Middle East in recent years, raising hopes that a prolonged period of confrontation could give way to renewed dialogue, economic recovery, and a more stable regional order.
