"I was so humbled and thrilled when I just heard the news", Ahmed said.
He called for more "concerted and collective partnership" on peace in the African continent.
The youngest head of government in Africa, however, still faces high expectations from young Ethiopians who want jobs, development, and opportunities. Africa's youngest leader quickly announced dramatic reforms and "Abiymania" began.
Ethiopia and Eritrea, longtime enemies who fought a war from 1998 to 2000, renewed relations in July 2018 after years of tension and hostility.
Within weeks, the visibly moved Eritrean president, Isaias Afwerki, visited Addis Ababa and communications and transport links were restored.
At home, he has made sweeping changes to a long-repressive government.
The committee's citation also says it hopes the prize will encourage efforts to promote reconciliation, solidarity and social justice.
Ethiopia, meanwhile, hopes the dam will become Africa's largest hydroelectric dam. Ethiopia's border with Eritrea was reopened a year ago as part of the peace talks, and then was abruptly closed a few months later.
"Peace does not arise from the actions of one party alone", Reiss-Andersen said Friday.
The U.S. Embassy in Ethiopia joined in the congratulations, noting the "incredible progress" made under Abiy.
The immediate demands of Ethiopian politics may leave Abiy with no choice but to shift his focus inward in the months to come. "He released political prisoners and journalists, unbanned opposition groups and appointed women to his cabinet, all within a year of being in office". 'Age of fake news' Experts also suggest that the five-person committee could this year decide to focus on freedom of expression and information, at a time when such freedoms are under pressure in both democracies and authoritarian regimes. In an Ethiopia that is socially conservative to the core, the prime minister's PR-guided demeanor - accompanied by an unprecedented "Abiymania" - has sparked some resentful allegations that the former secret service agent is engaged in illicit activities benefitting his ethnic group, the Oromo.
Amnesty International praised Mr. Abiy for his human rights achievements "after decades of widespread repression" in Ethiopia. Some observers warn that the unrest will grow ahead of next year's election. Improvements to Eritrea's human rights landscape has been limited -many of the country's residents remain increasingly isolated under Isaias's tight grip on power.
Ethiopia has many languages and ethnic rivalries within its own borders that Ahmed has worked to address. If Thunberg wins, she'd be the youngest Nobel victor in history. The Nobel committee, which has been awarding the recognition for 50 years, doesn't reveal the names of nominations.
The committee has in the past used its prestigious award to nudge a peace process forward and Friday's recognition of Abiy falls into that line of thinking.
The Integrated Schools Movement has been pipped to the post for a Nobel Peace Prize after losing out to the Ethiopian Prime Minister.
The president considered the Oslo award to the Ethiopian leader a good sign for peace processes in African countries and other nations, Buhari spokesman Femi Adesina said in a statement on Friday.
This week, 12 Nobel laureates have been named, of whom 11 are men. "Greta Thunberg not being awarded the Nobel Peace Prize means we can all enjoy a less chaotic news cycle from the volatile toddler in the Oval Office", said Charlotte Clymer of the Human Rights Campaign.
Two literature prizes were awarded Thursday: One for 2018 that went to Polish novelist Olga Tokarczuk and one for 2019 that was given to Austrian author Peter Handke.
