Sudanese capital Khartoum will host within days a trilateral summit in which the heads of state of Egypt and Sudan will partake, as well as Ethiopia's prime minister.
Egypt's state news agency MENA cited Sudanese Foreign Minister Ali Karti as saying that the meeting will take place on March 23.
Egyptian President Abdel Fattah al-Sisi, Sudanese counterpart Omar al-Bashir and Ethiopian Prime Minister Hailemariam Desalegn are due to attend alongside the irrigation and foreign ministers of the three countries.
Karti said that during the summit, the three countries will sign the agreement they reached after trilateral talks earlier this month.
As it stands, Egypt receives the largest share of the river's water and this water source is vital for the country with a population of 87.9 million.
When Ethiopia began construction of the hydroelectric Grand Ethiopian Renaissance Dam on the Blue Nile in 2011, concerns in Egypt surfaced regarding how the dam will affect its share of Nile water.
The announcement of the name of the international consultancy firm which will conduct studies on the effects of the dam was due on March 9, but was delayed. The firm will study potential impacts the construction may have on downstream countries Egypt and Sudan, particularly on their shares of water.
The trio's irrigation and foreign ministers met in Khartoum between March 5 to 8. They reached a draft agreement governing cooperation between them to benefit from the eastern Nile water and the dam.
Karti described the agreement as "historic" and said Sudan will invite several neighbouring countries to attend the ceremony.
