IRAN and Oman have agreed the geographic coordinates of a commercial shipping route through the Strait of Hormuz. Any understanding on the strait should be reached between Iran and Oman alone, he said. ‘Iran wants 5 per cent, Oman has suggested 3 per cent and the US wants no fees at all,’ he said. ‘We may see some creative ambiguity here where the terminology is changed, but it looks enough like fees for Iran to agree to it.’ Service and maritime charges tied to de-mining remain contentious, with Tehran insisting the clearance work be done by Iran.
