Algeria Gate: While work is underway on the first section of the Tindouf–Zouérate road, Morocco and Mauritania signed a framework agreement in Rabat on September 21 to rehabilitate and widen Mauritania’s National Road No. 4. Officially presented as a project to facilitate traffic between Nouakchott and Nouadhibou, the agreement carries a far broader strategic significance.
The road does not end at Nouadhibou. It extends north toward PK55, opposite Guerguerat, creating a continuous land route toward Dakhla. Moroccan Equipment Minister Nizar Baraka has himself publicly referred to the Nouakchott–Dakhla link via PK55. The agreement covers some 480 kilometers of the Mauritanian road network.
This is therefore about much more than improving bilateral trade.
Faced with Algeria’s plans to develop a southern corridor toward West Africa, Rabat is accelerating efforts to capture future commercial flows toward Mauritania, the Sahel and West Africa. The objective is to consolidate the Dakhla–Guerguerat–Nouadhibou–Nouakchott axis as the terrestrial backbone of Morocco’s westward economic projection.
Dakhla as the gateway
The future Dakhla Atlantic Port, estimated to cost close to $1 billion and expected to enter service in 2028, is intended to provide this strategy with its maritime outlet.
It is one of the instruments of Morocco’s so-called Atlantic Initiative, officially designed to provide landlocked Sahel countries with access to the Atlantic. But this initiative is not developing in an empty space.

Mauritania already possesses a major road corridor linking Nouakchott with Bamako, stretching roughly 1,350 kilometers. That route already provides Mali with a natural Atlantic outlet.
The strategic question for Rabat is therefore how to make Dakhla and the Dakhla–Nouakchott axis the northern extension of this commercial depth into the Sahel.
Morocco and Mauritania’s September 21 agreement reinforces precisely this north-south connectivity, linking the Mauritanian RN4 with the wider road network toward Guerguerat and, beyond it, Dakhla.
Mauritania caught between two corridors
Mauritania now finds itself at the intersection of two competing corridor strategies.
It can, of course, capitalize on this position to attract investment, infrastructure and commercial flows. That is legitimate economic statecraft.

But this central position also puts its proclaimed policy of “constructive neutrality” on Western Sahara to the test.
Western Sahara remains on the United Nations list of Non-Self-Governing Territories, while the Sahrawi people’s right to self-determination remains a central issue under the UN framework.
Yet Nouakchott is simultaneously participating in the consolidation of an economic axis connecting its territory to Guerguerat and Dakhla.
This raises an unavoidable political question: how far can diplomatic neutrality be maintained while economic integration with Morocco’s southern network continues to deepen?
The same ambiguity can be seen in the Nigeria–Morocco Atlantic African Gas Pipeline. Mauritania is among the countries involved in the project and would need to conclude the necessary agreements with Morocco for its implementation. Moroccan hydrocarbons authorities have also conducted offshore studies in the Dakhla area.
Road, port and gas pipeline are therefore gradually forming a single strategic architecture: turning Dakhla into an economic gateway toward West Africa and the Sahel, with Mauritania as the indispensable transit territory.
The Emirati dimension
There is, however, a third actor whose role cannot be overlooked: the United Arab Emirates.
As I have already pointed out in my previous analysis, “Mauritania at the Heart of the Moroccan-Emirati Offensive,” the UAE is deeply involved in a broader strategy that intersects with Morocco’s ambitions in West Africa and the Sahel.

In this reading, the objective is not simply to support infrastructure development. It is also to strengthen Emirati influence in a region where Morocco is seeking to expand its economic and strategic footprint, while drawing Mauritania further away from Algeria and closer to the countries aligned with the Abraham Accords.
The Emirati presence in Mauritania is not new. In 2020, Abu Dhabi announced around $2 billion in investment and development projects, alongside concessional financing. The Abu Dhabi Fund for Development has also financed infrastructure projects in Mauritania.
But Abu Dhabi is pursuing its own agenda as well — one that increasingly overlaps with Moroccan interests: expanding its influence over African ports, trade corridors and logistics chains.
This strategy extends far beyond Mauritania. Through AD Ports Group and DP World, the UAE has built a broad network of port concessions, logistics investments and commercial corridors connecting African markets with the Gulf, Asia and Europe.
Mauritania is particularly valuable within this architecture.
Its geographic position between the Maghreb, the Atlantic and West Africa makes it a natural transit point for regional trade. This is precisely where Moroccan and Emirati interests converge.
Rabat seeks to build the Dakhla–Guerguerat–Mauritania corridor toward West Africa. Abu Dhabi has the capital, port operators and logistics companies capable of investing in the infrastructure that can extend such corridors.
A battle over corridors, ports and influence
Mauritania is therefore sitting at the crossroads of two strategic projects.

For Morocco, it is the indispensable passageway for extending the Dakhla project toward West Africa and the Sahel.
For the UAE, it represents another node in a much broader port and logistics strategy spanning Africa and the wider maritime routes connecting the continent to the Gulf and beyond.
The road linking Dakhla, Guerguerat, Nouadhibou and Nouakchott must therefore be viewed in this wider context.
What is taking shape is not merely a road rehabilitation project. It is a broader contest over corridors, ports, energy infrastructure and the future movement of goods between the Maghreb, the Sahel and West Africa.
And, in my view, this dynamic is unfolding at the expense of the Sahrawi people and their internationally recognized right to self-determination.
