 Congo's president, the current head of the African Union, met on Sunday with Egyptian and Sudanese officials and made international regional efforts to relaunch negotiations over Ethiopia's disputed dam on the Nile River's main tributary. President Felix Tsishakiri was received by General Abdul Fattah Boran, head of Sudan's ruling sovereign council at Khatum's airport. The two leaders then headed for talks at the presidential palace. Sudan's Prime Minister, Abdullah Hamdok, also attended the talks, according to statements by the sovereign council. Foreign Minister Miriam Al-Maji said Congo's president had offered an initiative to break deadlock over the dam issue. She said the Sudanese authorities would study the initiative without elaborating. Tsishakiri then flew to Cairo, where he met with Egypt's president, Abdul Fattah El-Sisi. Ethiopia said the five billion dollar dam is essential, arguing that the vast majority of its population lacks electricity. Sudan wants Ethiopia to coordinate and share the data on the dam's operation to avoid flooding and protects its own power-generating dams on the Blue Nile, the main tributary of the Nile. The Blue Nile meets the White Nile in Khatum before winding northward through Egypt to the Mediterranean Sea.
