(FOX NEWS) — President Donald Trump said Wednesday that no country will be allowed to control the Strait of Hormuz, warning that the U.S. would act militarily if any side tries to dominate the key international waterway.

“International waters – nobody’s going to control it,” Trump said during the question and answer session during Wednesday’s monthly Cabinet meeting. “We’re going to watch over it. We’ll watch over it. But nobody’s going to control it.”

Trump said control of the Strait is part of ongoing negotiations, suggesting Iran wants a role in managing the passage.

“This part of the negotiation that we have, they would like to control it. Nobody’s going to control its international waters,” Trump said.

The president also referenced Oman, which Iranian state TV had earlier claimed could help manage ship traffic through the Strait under a disputed draft framework.

“And Oman will behave just like everybody else,” Trump said. “So we’ll have to blow them up. They understand that. They’ll be fine.”
