US Secretary of State Marco Rubio said the United States will not accept Iran controlling the Strait of Hormuz after talks collapsed.
Iran proposed reopening the strait and ending the war, but the US rejects any deal letting Iran set vessel access or tolls.
The strait, handling ~20% of oil and LNG exports, has been closed since a US‑Israel attack in late February, despite a ceasefire.
The US is enforcing a naval blockade to stop Iran‑linked vessels using the waterway, signaling heightened tensions in a key energy corridor.
