The dispute between Egypt, Ethiopia and Sudan over Addis Ababa’s construction of a gigantic dam on the Blue Nile has reached a new level.

On Monday, Egypt’s foreign minister urged the U.N. Security Council to adopt a resolution giving international clout to efforts to resolve the dispute over the hydroelectric dam.

Shoukry said the draft resolution is in line with the outcome of an African Union summit on Friday where the leaders of Egypt, Sudan and Ethiopia agreed to return to talks aimed at reaching an agreement.

The Grand Ethiopian Renaissance Dam (GERD), set to be Africa’s largest hydroelectric project, has been a source of tension in the Nile basin ever since Ethiopia broke ground on it nearly a decade ago.

Cairo sees the renaissance dam as a threat to international security, while Sudan fears its negative impact on its population.
