Ethiopias growth and transformation plan and its implications for synergic sum effect contextualized into regional cooperation in the horn of Africa

The East African region, in which Ethiopia is located, is commonly known as the Horn of Africa. It is branded for its economic underdevelopment and political instability. The region is economically poor, politically unstable and very volatile security wise. In lieu of this, it is prudent to describe the region as one that represents one of the most complex sub-regions in Africa. To resolve these and associated problems, states of the region are contributing a lot. interallia,, Ethiopia is striving level best possible individually and collectively via the regional framework. However, its role has been much challenged for its weak economy. Given this as it may, it’s now in a good track record of fast economic growth that sets the foundation for its transformation plan to get realized in the near future. In lieu of this, if its objectives stated under the second growth and transformation plan (GTPII) are achieved, it will add a momentum in Ethiopia’s regional role. But what is to be contributed? How? In which and what manner can the state is expected to play to the best of the regional scenario, are some of the very fundamental questions that the research is going to address throughout the research process. To address these questions and arrive at its research objective, the researchers have employed a proper methodological approach in terms of crafting theoretical paradigms, research design, techniques of data collection and analysis. Within this theoretical approach, the study has gleaned secondary data sources, and analytically examine them in a triangulated research design (descriptive, evaluative and document analysis). Hence, the study has examined Ethiopia’s trend in a broader manner and explored viable prospects in redressing the Horn’s much trouble pertaining to the nexus of security-peace-development challenges. According to the findings of the study, thus, Ethiopia will have the greatest propensity to play as a regional hegemony by complementing its missed link. Among others, it will create a new window of opportunity for increased interstate economic relations and viable conflict resolution approaches. Key words: Regional cooperation, horn of Africa, Ethiopia, hegemony.
