“We cannot continue this vicious cycle of circular talks indefinitely,” Sudanese Irrigation Minister Yasir Abbas said in a statement.
However, Egypt and Ethiopia, in separate statements, blamed Sudan’s objections to talks on the new stalemate.
Ethiopia sees the dam as key to plans to become Africa’s largest energy exporter. Egypt, which gets more than 90 percent of its rare fresh water from the Nile, fears the dam could devastate its economy.
Sudan said on Sunday it was worried that the dam could overwhelm the nearby Roseires dam if no agreement was reached to allow countries to share data.
Ethiopia said in a statement from the foreign ministry that, although it had previously insisted on meetings with African Union experts, Sudan opposed the terms of reference and refused to include experts in the meeting, effectively halting talks.
The protracted dispute between the three countries continued even after the tank behind the $ 4 billion dam began filling up in July.
“Sudan has insisted on assigning African Union experts to provide solutions to controversial issues … a proposal that Egypt and Ethiopia have reservations about,” Egypt’s foreign ministry said in a statement posted on social media.
In its own statement to the state news agency SUNA, Sudan said it had objected to what it said was a January 8 letter from Ethiopia to the African Union stating that Ethiopia was determined to fill the tank for the second year in a row. July with 13.5 million cubic meters of water, regardless of whether an agreement is reached or not.
In its own statement posted on the social networks of the Ministry of Foreign Affairs, Ethiopia said that “it took the initiative immediately to establish an efficient and reciprocal data exchange mechanism”.
