Egyptian President Abdel-Fattah El-Sisi and chairman of the Sovereign Council of Sudan Abdel-Fattah El-Burhan discussed bilateral relations in a telephone call on Saturday evening, the Egyptian presidency said.
The phone call came 24 hours after Sudan refused to endorse an Arab League resolution supporting Egypt in its dispute with Ethiopia over the Grand Ethiopian Renaissance Dam (GERD).
During the phone call, El-Sisi reaffirmed Egypt's commitment to supporting Sudan's stability and security, while Burhan praised Egypt's efforts to ensure Sudan's success during its transitional period.
Sudan has expressed "reservations" over the draft resolution proposed on Thursday by Egypt to the Arab League to support both Egypt and Sudan in the dispute over the GERD, which Ethiopia is building on the Blue Nile.
Sudan argued that the resolution does not serve its interests and expressed fears that it might result in "an Arab-Ethiopian confrontation."
Sudan is yet to sign an agreement on the GERD drafted by the US Treasury Department, whereas Ethiopia skipped the last round of US-mediated talks between the three countries in Washington.
Egypt, which initialled the agreement, described it as "fair and balanced" and said it "achieves the interest of the three countries," while Ethiopia accused the United States of being "undiplomatic" in its efforts to resolve the dispute
Ethiopia hopes the mega project will make it Africa's biggest power exporter. Cairo, however, fears the dam, which is under construction near Ethiopia's border with Sudan, would significantly diminish its water supply from the Nile, its major source of freshwater.
