Oman has told European officials there’s no way of going back to the pre-war status quo with the Strait of Hormuz and transiting ships may have to be charged some fees, according to people familiar with the matter.

While Omani officials said they will always abide by international maritime law, they added there could be fees for services related to de-polluting the strait or helping ships navigate it, the people said, asking not to be named discussing private matters. It’s unclear if Oman said all these fees would be obligatory.
