2021/01/03 23:44 CAIRO (AP) Egypt, Ethiopia and Sudan resumed their years-long negotiations Sunday over the controversial dam Ethiopia is building on the Blue Nile, officials said. The resumption came six weeks after Khartoum boycotted talks in November, urging the African Union to play a greater role in reaching a deal over the disputed Grand Ethiopia Renaissance Dam. The negotiations have centered on the filling and operation of the giant dam. Key questions remain about how much water Ethiopia will release downstream if a multi-year drought occurs and how the three countries will resolve any future disputes. Ethiopia has rejected binding arbitration at the final stage of the project.
