Keypoints:
- US uses Lobito Corridor to counter China
- Infrastructure becomes supply chain leverage
- Africa faces value addition dilemma
THE United States is recalibrating its engagement in Africa’s critical minerals sector through a targeted infrastructure strategy designed to compete with China’s entrenched dominance. According to IRIS, a Paris-based geopolitical think tank, in its report Lobito Corridor Project Vault: How the US is moving to compete with China in Africa’s critical minerals, Washington is repositioning itself by leveraging the Lobito Corridor to reshape mineral supply chains across the continent.
Why this matters
The report, released on April 20, argues that control over logistics—not just mines—will define the next phase of global competition for critical minerals. It frames the corridor as a ‘strategic lever’ in the global minerals race. By developing a westward export route linking Central Africa’s copper and cobalt belt to Atlantic markets, the United States is attempting to reduce reliance on China-influenced supply chains while embedding long-term strategic influence in Africa’s resource economy.
A corridor with global implications
The Lobito Corridor links the mineral-rich regions of the Democratic Republic of the Congo and Zambia to Angola’s Atlantic port of Lobito. As explored in earlier Africa Briefing reporting on US–EU cooperation, the project has already attracted coordinated Western backing aimed at securing access to key minerals.
While the infrastructure itself is not new, the IRIS report underscores its growing importance in the context of intensifying global competition for critical minerals.
By enabling a westward export route, the corridor introduces a structural alternative to traditional pathways that have long defined African mineral trade. This shift is not merely logistical—it reflects a deliberate effort to realign supply chains in favour of Western markets.
Project Vault and supply chain strategy
A central theme in the IRIS analysis is the concept of supply chain leverage.
China’s dominance in Africa’s critical minerals sector is deeply embedded, spanning extraction, processing, and logistics. This aligns with broader trends explored in Africa’s critical minerals reshaping global power dynamics, where control over supply chains increasingly defines geopolitical influence.
In contrast, the United States has historically lacked a coordinated state-backed approach.
Project Vault represents a strategic departure. Rather than attempting to replicate China’s comprehensive model, the United States is targeting specific leverage points—particularly infrastructure that determines how minerals move from inland mines to global markets.
By shaping export routes, Washington can influence supply chains without necessarily controlling upstream or downstream assets.
Critical minerals and strategic urgency
The IRIS report situates the Lobito Corridor within the broader context of the global energy transition.
Minerals such as copper and cobalt are essential inputs for electric vehicles, renewable energy systems, and advanced technologies. The urgency of securing these resources is evident in Washington’s growing engagement in the region, including efforts highlighted in US moves to secure DR Congo’s copper and cobalt.
The Democratic Republic of the Congo plays a central role in cobalt supply, while Zambia remains a key copper producer. Together, they form one of the world’s most critical mineral hubs.
Ensuring stable and diversified access to these resources has become a priority for major economies, and the Lobito Corridor is positioned as a mechanism to achieve that goal.
Infrastructure as influence
A key insight from the IRIS analysis is that infrastructure should be understood as an instrument of geopolitical influence.
Transport corridors do more than facilitate trade; they shape long-term economic behaviour. Once established, they define preferred routes, create dependencies, and influence investment flows.
By supporting the Lobito Corridor, the United States and its partners are embedding themselves within the economic architecture of Central and Southern Africa.
This creates structural power beyond immediate returns.
Contrasting models of engagement
The IRIS report draws a clear distinction between the US approach and China’s established model in Africa.
China’s strategy is characterised by comprehensive involvement across the value chain, supported by state-backed financing and long-term investment. This has enabled Beijing to dominate both extraction partnerships and processing capacity.
The United States, by contrast, is adopting a more focused approach centred on infrastructure and supply chain dynamics.
This evolving competition is also visible in resource diplomacy across Southern Africa, including efforts detailed in US engagement in Zambia’s copper sector.
According to IRIS, this reflects a pragmatic strategy—targeting areas where influence can be exerted more effectively without replicating the full scope of China’s engagement.
Economic potential and regional impact
The Lobito Corridor presents significant economic opportunities for the countries it connects.
Improved transport infrastructure can cut export costs, boost volumes, and attract new investment. The corridor also has the potential to stimulate broader economic activity along its route, including in agriculture and trade.
The IRIS report notes that enhanced connectivity could strengthen regional integration between Angola, the Democratic Republic of the Congo, and Zambia.
However, these benefits depend on effective governance and coordinated policy implementation.
The persistent challenge of value addition
Despite its potential, the corridor raises important structural questions about Africa’s role in global supply chains.
The IRIS analysis highlights the risk that improved export infrastructure may reinforce existing patterns of raw material extraction without promoting local industrialisation.
Africa continues to export a large share of its mineral wealth in unprocessed or semi-processed form. The Lobito Corridor, while improving logistics, does not inherently alter this dynamic.
Addressing this imbalance will require deliberate efforts to develop processing and manufacturing capacity within the continent.
African agency in a competitive landscape
The IRIS report emphasises that African countries are not passive actors in this process.
Instead, they are operating within a competitive global environment in which multiple powers are seeking to secure influence. This creates opportunities for governments to negotiate better terms and attract investment.
The corridor can therefore serve as a platform for strategic bargaining.
At the same time, managing these relationships requires careful policy choices to ensure that national interests are prioritised.
Governance and sustainability considerations
The success of the Lobito Corridor will also depend on how social and environmental challenges are addressed.
Large infrastructure projects can have significant impacts on local communities, including land use changes and displacement. Ensuring that these impacts are managed responsibly is essential for long-term sustainability.
The IRIS report also underscores the importance of governance frameworks in maintaining transparency and accountability.
Strong institutional oversight will be critical in ensuring that the corridor delivers inclusive and sustainable outcomes.
A long-term strategic recalibration
The IRIS report frames the Lobito Corridor as part of a broader, long-term recalibration of US strategy.
Project Vault reflects an effort to reassert influence in a sector where China has established a dominant position. By focusing on infrastructure and logistics, the United States is seeking to build a foothold that can evolve over time.
For Africa, the corridor presents both opportunities and challenges—offering the potential for investment and integration, while underscoring the need for strategic policymaking.
Reshaping the mineral map
The IRIS report makes clear that the Lobito Corridor is more than a transport project—it is a strategic intervention in the global competition for critical minerals.
By targeting infrastructure, the United States is attempting to reshape the routes through which resources flow, thereby influencing the broader supply chain.
Whether this strategy succeeds will depend on execution, coordination, and alignment with African development priorities.
As demand for critical minerals continues to rise, the corridors that move them will become increasingly central to global power dynamics—and the Lobito Corridor stands at the heart of that transformation.
