An underwater tunnel proposed to link the shores across the Straits of Gibraltar has long lived in media chatter, yet the bold idea has repeatedly stalled. Recently, headlines in both Spain and Morocco have revived talk of the tunnel’s feasibility, set against a backdrop of a warming bilateral mood following tensions in 2021. The improving relationship between the two nations is now seen as a possible platform for revisiting major cross-border projects and regional integration, including potential collaboration on broader infrastructure and economic initiatives as part of Spain and Portugal’s shared candidacy to host the 2030 Men’s Football World Cup.
Earlier this year, a notable moment occurred when a high-ranking Spanish official described Morocco’s proposal for Western Sahara autonomy as a serious, realistic, and credible foundation for resolving differences. A year has passed since a pivotal diplomatic letter helped ease the sharpest strains between Madrid and Rabat, beginning a period of reconciliation that has allowed Spanish officials to renew visits and discussions with Moroccan leadership. Since that letter, the Spanish prime minister has traveled to Rabat on multiple occasions, with another visit anticipated. In addition, ministers from both countries have met numerous times to push forward dialogue across strategic areas.
Within Morocco, the shift in Spanish policy is viewed as a significant breakthrough, reflecting Spain’s historical influence in the region. Amin Ater, editor-in-chief of Tel Quel, notes that the change signals a decisive moment in consolidating ties with Europe at a time when Rabat seeks to diversify its global partnerships. He emphasizes that strong Spain-Morocco relations matter not only for bilateral interests but also for Morocco’s broader strategy to expand influence across European and regional markets, including South America, where diversification is a priority.
Praise for the Spanish position
Other Moroccan media highlight that the Spanish government has weathered both internal and external pressures, with some critics in Algeria and domestic political groups weighing in on the autonomy plan. Morocco has argued that Spain’s stance opens a new pathway for cooperation, and officials in Rabat have repeatedly praised Spain for demonstrating courage and historical realism in this moment. A key message from Rabat’s leadership during high-level meetings is that Madrid’s support strengthens mutual interests and stabilizes regional relations in Europe and North Africa.
At recent summits, both sides announced a broader package of cooperation, including expanded financing and opportunities for Spanish businesses eager to invest in Morocco. The North African country has signaled a willingness to involve Spanish firms in future priority projects, such as urban renewal programs and the modernization of rail networks. The dialogue is framed as a mutual effort to expand collaboration across security, trade, and infrastructure, with additional commitments aimed at preventing future conflicts and aligning legal frameworks to reduce friction in cross-border activities. Migration cooperation also features prominently, contributing to redirected flows and managed mobility while addressing enforcement and humanitarian considerations on both shores.
Yet challenges persist on the other side of the equation. The relationship between Madrid and Algiers has cooled over Madrid’s support for Morocco’s Western Sahara autonomy plan. Current tensions have led to a freeze in some bilateral exchanges, with Algeria limiting certain trade measures and seeking to strengthen ties with other European partners to shift energy routes. For now, gas deliveries from Algeria to Europe continue, even as Rabat and Rabat-linked interests push to position North Africa as a central energy corridor feeding the wider European market. The evolving energy geopolitics adds a layer of complexity to the broader regional strategy and the potential success of cross-border projects such as a Gibraltar tunnel.
