About this relationship

Angola and South Sudan, both members of the African Union, have had essentially no substantive bilateral engagement, Angola situated in Southern Africa and South Sudan, the world's youngest nation, having gained independence from Sudan in 2011, on its own recovery from prolonged internal conflict. South Sudan has drawn heavily on United Nations peacekeeping and humanitarian support since independence, with Angola rarely featuring in its diplomatic priorities beyond shared African Union membership. Trade and diplomatic contact between the two nations are effectively nonexistent, with no meaningful bilateral channel connecting them.

About Angola

Angola is a country located in southern Africa. It is bordered by Namibia to the south, Zambia to the east, and the Democratic Republic of the Congo to the north. The capital of Angola is Luanda.

Angola has a long history of political instability and conflict. From 1975 to 2002, the country was embroiled in a civil war that killed an estimated 500,000 people and displaced millions. In 2002, a peace agreement was signed, bringing an end to the fighting and paving the way for the country's first democratic elections in more than 20 years.

Since then, Angola has made significant progress in rebuilding its infrastructure and economy, which had been severely damaged by the war. The country is rich in natural resources, including oil and diamonds, and has become a major oil producer in Africa. However, despite its economic growth, Angola still faces challenges such as high poverty rates and a lack of access to education and healthcare for many of its citizens.

In terms of international relations, Angola is a member of the African Union and the Southern African Development Community, and it has strong ties with other African countries as well as with China, Brazil, and Russia. The country has also played a role in regional peacekeeping efforts, including in the Democratic Republic of the Congo and in Sudan.

Geography & terrain

Varied terrain: a narrow coastal plain along the Atlantic rising to an interior plateau and highlands, with tropical forest in the north and drier savanna toward the south. Climate is tropical, moderated by altitude inland. The plateau escarpment and thick vegetation complicate overland advance, while the long coastline is more open to attack from the sea.

About South Sudan

South Sudan is a country in East-Central Africa that gained independence from Sudan in 2011. It is bordered by Sudan to the north, Ethiopia to the east, Kenya to the southeast, Uganda to the south, the Democratic Republic of the Congo to the southwest, and the Central African Republic to the west.

Since its independence, South Sudan has been embroiled in conflict and political instability. In 2013, a civil war broke out between the government and opposition forces, leading to widespread violence and displacement. A peace agreement was signed in 2015, but the fighting has continued and the country has struggled to rebuild and stabilize.

South Sudan is one of the poorest countries in the world, with a weak economy that is heavily dependent on oil exports. The country has a very young population, with more than half of the population under the age of 18. It also has a high rate of illiteracy and limited access to education.

In recent years, there have been efforts to promote peace and reconciliation in South Sudan, including through negotiations and the deployment of peacekeeping forces. However, the situation in the country remains fragile and there are ongoing challenges to building a stable and prosperous society.

Geography & terrain

Landlocked, no coastline. Terrain is dominated by vast, seasonally flooded swamplands (the Sudd) and savanna plains, with highlands near the southern border. Climate is tropical with pronounced wet and dry seasons. The wetlands and seasonal flooding form a significant natural barrier that has historically hampered outside movement, though the open plains elsewhere offer little protection.

Solo scenario: Angola vs South Sudan

Battle narrative

Initial phase

South Sudan's larger military budget and stronger air power give it an advantage in the initial stages of the conflict, with the ability to target key military positions and infrastructure.

Force composition

Angola can also call on significantly more personnel, counting both active-duty and reserve forces. Angola also holds a clear naval edge.

Ground campaign

Angola's terrain could make a rapid ground campaign difficult: The plateau escarpment and thick vegetation complicate overland advance, while the long coastline is more open to attack from the sea. Port of Luanda would likely be a focal point of the campaign: The capital and Angola's largest port, the principal entry point for imports and the base for naval operations. South Sudan's terrain could make a rapid ground campaign difficult: The wetlands and seasonal flooding form a significant natural barrier that has historically hampered outside movement, though the open plains elsewhere offer little protection. Juba would likely be a focal point of the campaign: The capital on the White Nile holds the country's main airport and is the seat of government and military command. Angola's larger population could also support a prolonged resistance.

Prolonged conflict

Angola's stronger economy could help sustain military operations in a prolonged conflict. South Sudan also devotes a larger share of its economy to defense (about 16.9% of GDP), a more militarized posture that could be easier to sustain over time. Occupying Angola outright would likely prove costly given its terrain.

Overall assessment

Overall, the numbers favor Angola, giving it an estimated 64.9% chance of coming out on top. Turning that edge into a decisive win over South Sudan — and holding any ground taken — would still be far from guaranteed.
