Iran and Oman want new rules for ships. Both countries lie at an important water way. This is the Strait of Hormuz. Many ships bring oil and gas past this place. Iran blocked the way some time ago.
Now a plan exists for a new route. Ships shall drive in on one side. They shall drive out on the other side. Iran wants to check the ships. The country asks maybe for money for the trip. This is a service fee.
Problems still exist. Iran says the USA make the way unsafe. Mines lie in the water. These are dangerous bombs. It takes 30 days to remove these mines. Donald Trump says the opening comes very soon. Experts are not sure yet.
