Iran says Strait of Hormuz will stay closed until US changes its conduct, Trump reiterates claim of American control

President Donald Trump posted a map on his Truth Social platform that labels the Strait of Hormuz as "new American territory," reviving a claim he first voiced in mid-August. The map had previously been shared on August 18, and Trump has not provided further comment on the image.

The strait, a key global shipping lane through which about 20% of crude oil and liquefied natural gas exports pass, has been closed by Iran since the start of the regional conflict. Tehran maintains that it controls the passage, while Trump asserts that the United States "fully controls" it.

Iranian Deputy Foreign Minister Kazem Gharibabadi responded to Trump’s remarks, stating that the former president’s “illusions about the Strait of Hormuz will be corrected soon.”

Mohsen Rezaei, secretary of Iran’s Supreme National Security Council, told state television that the strait will stay closed until the United States honors its commitments and alters its "behaviour." > "The Strait of Hormuz is closed, despite American claims, and it will not be opened until America corrects its behaviour... This time, America must first honour its commitments," Rezaei said.

Rezaei also warned other countries against joining U.S. sanctions, saying any nation that participates in economic restrictions would be considered an enemy and could face retaliation. He noted that Iran’s attacks have so far targeted U.S. military bases only, but warned that economic sanctions could prompt strikes on oil companies and other businesses.

The United States and Iran signed a memorandum of understanding in June to end hostilities and negotiate broader agreements, but talks have stalled over navigation arrangements in the Strait of Hormuz. Ongoing discussions with Oman have yet to produce a definitive settlement.
