DUBAI, Sept 16, 2018 (News Wires) - Leaders from Ethiopia and Eritrea signed a "peace agreement" on Sunday during a summit in Saudi Arabia, yet another sign of warming ties between two nations that have face decades of war and unease. Terms of the agreement signed by Ethiopian Prime Minister Abiy Ahmed and Eritrean President Isaias Afwerki weren't immediately clear. Saudi authorities did not respond to specific questions about the accord, which earlier had been described as being a further endorsement of a historic deal reached between the two nations in July. "The peace deal resulted in restoration of normal relations between the countries, on the basis of the close bonds of geography, history and culture between the two nations and their peoples," Saudi Arabia said in a statement Sunday, calling the accord the "Jiddah Agreement." "The kingdom of Saudi Arabia praised the leaders of Ethiopia and Eritrea for exercising leadership and courage to restore the brotherly relations between the two countries, thus forming the foundation for a new phase that will bring significant developments in the relations between the two nations in all fields," the statement added. Saudi King Salman and his 33-year-old son, Crown Prince Mohammed bin Salman, were on hand for the summit in the Red Sea port city of Jiddah. Also attending was Emirati Foreign Minister Sheikh Abdullah bin Zayed Al Nahyan and United Nations Secretary-General Antonio Guterres. The Ethiopian and Eritrean leaders also were awarded for their efforts the Order of Abdulaziz Al Saud Medal, the kingdom's highest civilian honor. Abiy and Isaias signed a "Joint Declaration of Peace and Friendship" on July 9, ending 20 years of enmity and formally restoring diplomatic relations between Ethiopia and Eritrea.
