Heads of state and government in the IGAD grouping are gathered in the Ethiopian capital, Addis Ababa for the 33rd summit.
During this 33rd IGAD summit, warring factions in South Sudan are expected to sign last revitalized peace agreement.
IGAD is the acronym for Intergovernmental Authority on Development – members include; Djibouti, Ethiopia, Kenya, Somalia, Sudan, Eritrea, South Sudan and Uganda.
Member states of this grouping seek to enhance regional cooperation in three priority areas of food security and environmental protection, economic cooperation, regional integration and social development peace and security.
Meanwhile, IGAD Council of Minister Wednesday discusses the relations between strained Sudan and Eritrea, as Addis Ababa strives to consolidate the normalization of its bilateral relations with Asmara.
This Council of Ministers held an ordinary session to discuss the South Sudan peace process and relations of Djibouti and Sudan with Eritrea which announced its return to the regional body.
Addis Ababa recently mediated successfully to reconcile Eritrea with Somalia and Djibouti but things seem a little bit different with Sudan.
Earlier this year, Sudan accused Eritrea of backing Sudanese rebels who prepare to launch an attack on its border town, Kassala and deployed thousands of troops along the border.
Sudanese officials say Asmara continue to host rebels from Darfur armed groups and Eritrean government says Sudan supports Eritrean rebels.
Relations between Asmara and Khartoum deteriorated following the signing between Sudan and Ethiopia of several pacts including a joint defence treaty in 2014 while Eritrea was at war with Ethiopia.
President Afewerki of Eritrea is supposed to attend the meeting of the IGAD leaders with President al-Bashir of Sudan.
