Sudan on Monday said that negotiations over Ethiopia's massive and controversial dam construction on the Blue Nile have been postponed for a week.
Talks between Ethiopia, Egypt and Sudan were suspended last week after Addis Ababa insisted on linking them to renegotiating a deal on sharing the waters of the Blue Nile.
"A meeting at the level of ministers of the three countries took place on Monday, during which Sudan asked to postpone the next meeting for one week for internal consultations," Sudan's water ministry said in a statement.
Egypt and Sudan view the Grand Ethiopian Renaissance Dam (GERD) dam as a threat to vital water supplies, while Ethiopia considers it crucial for its electrification and development.
South Africa, which holds the presidency of the African Union and is mediating negotiations, has urged the countries to "remain involved" in the talks.
