Could Abu Dhabi be the key to solving the intractable GERD dispute? The UAE is offering to act as an arbiter in the GERD dispute between Egypt, Ethiopia, and Sudan, Sudanese news agency SUNA reported. A delegation from the Emirati Foreign Ministry announced the bid yesterday during a visit to Khartoum. The three sides have been unable to agree a format for a new round of talks, with a meeting earlier this week failing again to break the deadlock.
