Ethiopian Prime Minister Abiy Ahmed and Eritrean President Isaias Afwerki signed a historic agreement on July 9, 2018, in Asmara, Eritrea, ending over two decades of open hostilities and war. The Joint Declaration of Peace and Friendship (Joint Declaration) marks a fundamental change for the Horn of Africa, with the reconciliation possibly altering the economic and political dynamics of the region. The Joint Declaration resulted from several key developments occurring over a few weeks from June through early July 2018. Ethiopia announced its acceptance of the original Algiers Agreement, dated December 12, 2000, which had never been implemented, and its willingness to abide by the 2002 international Eritrea-Ethiopia Boundary Commission (EEBC) ruling that awarded disputed territory to Eritrea, including the border town of Badme. Previously, Ethiopia had rejected the ruling and asked for a new ruling. Ethiopia had also previously insisted that relations must be restored before any territorial resolution. President Afwerki agreed to negotiate, after stating for years that Ethiopia had to withdraw its troops from the disputed town of Badme first. A few weeks before the signing of the Joint Declaration, the Eritrean foreign minister visited Addis Ababa, the capital of Ethiopia, marking the first bilateral meeting between the two since the war began.
