DUBAI, Aug 5 (Reuters) - Iran and Oman have reached an understanding on the geographic coordinates for a ‌shipping route through the Strait of Hormuz, and ‌a joint announcement is being finalised, provided certain third parties did not ​interfere, Iran's Foreign Ministry spokesperson Esmaeil Baghaei said on Wednesday. Baghaei added that any such agreement between Iran and Oman would not, by itself, guarantee security in the strategic waterway. The ‌proposed deal between ⁠Iran and Oman would give Tehran control over ships entering the Gulf through the Strait ⁠of Hormuz, a senior Iranian source and two regional officials told Reuters on Wednesday, in one of the biggest concessions ​yet to ​Iran. Iran's Foreign Ministry spokesperson Esmaeil Baghaei described the negotiations between Tehran ‌and Muscat as "professional" and "moving forward", saying "the ​two sides had reached a mutual ​understanding on the ​geographical parameters of the route under discussion".
