"The Strait of Hormuz is completely open and ready for business and full passage," Trump wrote on Truth Social. "But the naval blockade will remain in full force and effect as it pertains to Iran, only, until such time as our transaction with Iran is 100% complete."
Trump said he expects the process to go "very quickly," adding that most of the points have already been negotiated. He later said Iran with the help of the U.S., has removed or is in the process of removing all sea mines it had placed in the strait.
Israel and Lebanon on Thursday announced a 10-day pause in fighting, which is separate from the ceasefire in the U.S. and Israeli war against Iran that's due to expire next week.
The war on Iran, which started on Feb. 28, has killed thousands of people and destabilized the Middle East.
The conflict led Iran to effectively close the Strait of Hormuz, through which a fifth of the world's oil and liquefied natural gas transits, threatening the worst oil shock in history. The U.S. military blockade of Iran's ports followed after talks last weekend in Pakistan ended without agreement.
