The deal actually benefits and favors Ethiopia more than Somaliland. Ethiopia gets a naval base, a port, fish, and access to other rich resources situated on the coast. In return, Somaliland gets recognition from a country gripped with sanctions, international scrutiny, and a civil war. Somaliland also has a stake in Ethiopian airlines, and their profit margins often fluctuate. Ethiopian airlines could very well go bankrupt in the coming years.
If the Somaliland government was smart, they would ask Ethiopia to lease them farmland. Currently, Somaliland imports close to 90% of its food. Somaliland should have asked the Ethiopian government to lease them 100,000 hectares of land to grow crops. This would have helped improve their food security.
The Somaliland government should have also requested a significant stake in profitable industries in Ethiopia, like food processing and manufacturing.
