CAIRO (BLOOMBERG) – Egypt has issued another appeal to the United Nations Security Council in its long-standing dispute over the massive dam Ethiopia is building on a tributary of the Nile.

In a letter, Egyptian authorities alleged that Ethiopia had thwarted efforts to reach a binding legal agreement on issues related to the Grand Ethiopian Renaissance Dam that would safeguard the interests of all nations.

The African Union-mediated talks reached another stalemate in April.

Arab foreign ministers will discuss the dam at an “emergency” meeting in Qatar’s capital Doha on Tuesday (June 15th), the official Egyptian Middle East News Agency reported.

Egyptian Foreign Minister Sameh Shoukry also shared his concerns about the project, known as Gerd, with UN Secretary-General Antonio Guterres last year.

U.S. officials in the Trump administration, including then-Treasury Secretary Steven Mnuchin, tried to facilitate negotiations.

Ethiopia adopted the first phase of filling the dam reservoir last year.

Downstream, Egypt and Sudan, fearing possible disruptions to their water supplies, including in times of drought, oppose any unilateral decision by Ethiopia to resume pooling due to the rains. to come without an agreement on the filling and operation of the facility.

Gerd, designed to boost Ethiopia’s electricity production, sits on the Blue Nile about 45 km from the Sudanese border.

The river, which originates in Ethiopia, joins the White Nile near Khartoum, Sudan, with the Nile then flowing north through Egypt to the Mediterranean.
