Saudi Arabia and Sudan: One Geography, Two States in Red Sea Security Strategy

The Red Sea does not recognize political borders as maps draw them. Instead, it binds every coastal state to the shared fate of their neighbors across the water. When the western shore of this sea trembles, the eastern shore cannot remain still. This is the geopolitical reality Saudi Arabia has understood through decades of handling crises in the Horn of Africa and Yemen as a direct extension of its domestic security.

It is from this deep understanding of geography as shared destiny that the agreement to establish the Saudi-Sudanese Coordination Council, signed in Riyadh on 17 August 2026, should be viewed. It is the institutional manifestation of Saudi Arabia's firm belief: the stability of a unified Sudan is an indispensable condition for the stability of the Kingdom, and the collapse or division of Sudan will surely become a national security crisis for Saudi Arabia.

Historical Relations and Shared Cultural Foundations

Before strategic calculations and geopolitical crises emerged, Saudis held the Sudanese in high esteem and considered them the closest of people. From ancient times, the people of the Hejaz shared cultural and linguistic similarities with those across the Red Sea, particularly the Sudanese.

Throughout modern history, relations between the two countries have not experienced serious crises. A unique historical fact: this relationship has never witnessed political crises between the two states or between their peoples, and mutual respect has always prevailed. This special relationship, rooted in religious, cultural, and social ties, has made the two countries a rare model in intra-Arab relations, weathering every regional storm.

Saudi Arabia has stood by the Sudanese in every trial, from Nile floods and natural disasters to Sudan's crises and civil wars. This has created a network of human connections that far exceeds narrow political interests. It is this unique historical legacy that makes Saudi mediation welcome to both sides when war broke out, with the Jeddah platform working to de-escalate conflict and address the humanitarian crisis.

Therefore, Saudi Arabia's current stance toward Sudan is not merely the product of cold strategic or political calculations. It is a natural extension of a relationship that has lived in the hearts of the people long before being institutionalized through agreements.

Strategic Cooperation Framework

This relationship reaches its peak in the Saudi-Sudanese Coordination Council, with the founding agreement signed in Riyadh on 17 August 2026 by the two foreign ministers, Prince Faisal bin Farhan Al Saud and Mr. Mohieddin Salem. Sources indicate this is not just an ordinary diplomatic framework, but a comprehensive institutional platform overseeing ten major strategic areas. These areas reflect the depth of the partnership and the desire to move from political and humanitarian support to long-term strategic, economic, and investment cooperation.

The ten areas covered by the council include: Sudan's reconstruction; agriculture and food security; livestock; gold and mining; the Red Sea and seaports; energy and electricity; finance and banking; industry and food processing; communications and digital transformation; and tourism, real estate, and services.

Collectively, these areas form an integrated roadmap to transform bilateral relations into a genuine development partnership, leveraging Saudi Arabia's investment and technological capabilities alongside Sudan's enormous natural and human resources.

According to Sudan's Foreign Minister, the council's priorities focus on security, defense, and the economy, with the Red Sea added as a strategic cooperation area due to its importance to both nations. This is why Sudan joined the maritime defense alliance established by Saudi Arabia on 30 July 2026. This reflects a shared understanding that security and stability are prerequisites for any economic development, and that Red Sea security is a joint responsibility inseparable from the stability of coastal states.

Sudan and the Broader Arab Project

For over a decade and a half, the Arab region has witnessed a wave of systematic division projects targeting key states such as Iraq, Syria, Libya, Yemen, and Somalia. Countries that once played active roles in the regional order have become open conflict arenas managed by regional and international parties through local proxy forces. With its immense resources and vital position connecting the Arab world to the African hinterland, Sudan has always been an ideal target for such division projects.

When Saudi Arabia acts to support a path protecting the unity of the Sudanese state and its national institutions, it objectively contributes to stopping a link in the conspiracy against the entire Arab world. Every Arab state protected from division is a defeat for these projects, while every state that succumbs is a victory that encourages their repetition. From this perspective, Sudan's stability is a collective Arab battle, and Saudi Arabia finds itself in a position to lead that battle to protect a collective Arab project that cannot afford to lose another link.

Sudan in the Regional Equation

Sudan occupies a unique position that makes it one of the most important strategic keys of the region: it is the Arab state bordering both the Red Sea and the Nile, connecting the Horn of Africa to the Sahara, the Sahel, and the Arab hinterland, while sharing borders with seven African and Arab countries.

This position makes Sudan a natural bridge between the Arab world and Africa, a vital maritime gateway on the Red Sea, and a strategic water node on the Nile.

If a country in such a position were divided, it would open a geopolitical rift with influence stretching from the Nile Basin to the Bab al-Mandeb Strait, from the African Sahel to the Arabian Peninsula. Yemen's recent experience has clearly demonstrated that the collapse of a Red Sea state can turn a vital maritime chokepoint like Bab al-Mandeb from a safe trade route into a direct arena threatening global shipping.

Saudi Arabia, which has paid a heavy price both in security and economic terms due to the war in Yemen, has realized that the security of waterways cannot be protected only by guarding those routes, but by ensuring the stability of the states whose coastlines surround them.

Security Beyond Borders

In classical and modern strategic thinking, the security of any major state is measured not only by its direct borders, but also through its "strategic depth": the wider geographic expanse that absorbs shocks before they reach the core. This idea, originating from strategic thinkers such as Nicholas Spykman and Walter Lippmann, holds that a state exists within a geopolitical environment that acts either as a buffer absorbing crises or as a conduit transmitting and amplifying them.

As a key regional power, Saudi Arabia cannot simply be satisfied with protecting its direct borders while crises rage across its strategic neighborhood. From this perspective, Sudan is not just a neighbor across the sea, but one of the most important components of Saudi Arabia's strategic depth. Sudan's stability means stability along the Kingdom's western maritime frontier, control over irregular migration and smuggling flows, and prevention of the emergence of a security vacuum that armed groups and extremist organizations could exploit.

When Riyadh invests in Sudan's reconstruction and development through permanent institutional frameworks like the Coordination Council, it is building a wall of stability around its strategic depth. Riyadh understands that real security cannot be purchased with walls, but is built through the prosperity of neighbors.

Saudi Arabia's New Approach to Red Sea Security

The security of major waterways is not only a product of military protection of the route itself, but also of the strength and stability of the states along its shores. A Red Sea surrounded by weak or collapsed states, or penetrated by irregular forces, will be an unsafe Red Sea regardless of the military capabilities of the powers on its shores.

From this lesson, a more mature Saudi vision has emerged: it is not enough for the Kingdom to be strong on the eastern shore; states along the western shore and the southern approaches to the Red Sea — including Sudan, Eritrea, Djibouti, and Somalia — must also be strong, cohesive, and capable of enforcing full sovereignty over their coastlines. By placing the "Red Sea" alongside security and defense among its focus areas, the Saudi-Sudanese Coordination Council puts this philosophy into practice: strengthening Sudan's ability to control its coastline is a direct Saudi investment in the security of the entire Red Sea.

The Responsibility of a Regional Power

The Saudi-Sudanese Coordination Council expresses a broader political philosophy that Riyadh pursues: a true regional power does not become stronger by isolating itself behind borders, but by assuming responsibility for the stability of the surrounding region. At a time when division projects are escalating, supporting Sudan's unity, consolidating Saudi Arabia's strategic depth, and protecting Red Sea security are three sides of the same coin.

When Saudi Arabia protects the unity of its neighbor, it protects the integrity of its own strategic project. When it safeguards the stability of the Sudanese coast, it safeguards its own stability. That is the dialectic of shared geography: no neighbor can be safe if the other is not, and no shore can be stable if the opposite shore is unstable.
