Months of blockades and uncertainty around the Strait of Hormuz have pushed energy exporters to look for ways to bypass the key shipping lane.
Iranian officials had insisted the waterway would remain closed and negotiations would not resume unless the United States complied with a June framework agreement and offered compensation to Tehran for alleged violations.
US President Donald Trump, however, said on Monday that the US Navy already controls the Strait of Hormuz.
"We've mine swept the entire strait," he told reporters at the White House.
The narrow waterway between Iran and Oman is one of the world's most critical oil shipping routes. Before the Iran war, it carried around 20% of global crude exports from the Persian Gulf to markets in Europe, Asia and North America.
