The Lobito Corridor: A Railway That Could Redraw Africa's Mineral Trade

The Democratic Republic of Congo and Angola have signed a US-backed railway agreement to move minerals to the Atlantic coast, a deal that could cut a journey that currently takes up to a month down to about a week. Backed by up to $1 billion in proposed US funding, the project shows how mineral supply chains, not just diplomacy, are becoming a central part of great power competition on the continent.

The Lobito Corridor is not a brand-new idea. Parts of the railway line connecting the mineral-rich interior of Central Africa to Angola's Atlantic coast port of Lobito have existed for over a hundred years, originally built during the colonial era to move copper and other resources out of the region. For decades afterward, war, neglect, and lack of investment left much of the line in poor condition, making it slow, unreliable, and far less useful than it could have been.

That is now changing. The Democratic Republic of Congo and Angola have signed a new agreement, backed by the United States, to modernise and extend this railway corridor. The goal is straightforward: move minerals, particularly copper and cobalt, from Congo's resource-rich interior directly to the Atlantic for export, cutting out the much longer and more expensive routes currently used, many of which involve trucking materials across multiple borders before reaching a port.

The scale of the improvement being promised is significant. Currently, moving minerals from parts of the DR Congo to a port can take up to **30 days**, depending on road conditions, border delays, and the reliability of transport available. Once the Lobito Corridor is fully operational, that same journey could fall to roughly **one week**. For mining companies operating on tight margins and global supply chains that increasingly demand speed and predictability, that kind of time reduction is not a minor convenience. It directly affects cost, reliability, and how competitive Congolese and Angolan minerals are on the global market.

This matters even more given what's actually being moved. Cobalt and copper are both essential ingredients in batteries, electric vehicles, and much of the technology powering the global shift toward renewable energy. The DR Congo alone produces a large share of the world's cobalt supply, making reliable transport infrastructure out of the country a genuinely strategic issue, not just a local economic one.

The United States has proposed funding of up to **$1 billion** for the project, a figure that reflects how seriously Washington is treating mineral supply chains as a matter of long-term strategic competition, particularly against China, which has spent over a decade building deep mining and infrastructure investments across the African continent. For years, Chinese companies have dominated financing and construction of mining infrastructure in Central Africa, giving Beijing significant influence over how these critical minerals reach global markets.

The Lobito Corridor represents one of the more concrete US attempts to offer an alternative. Rather than simply criticising China's involvement in African mining, Washington is now backing a specific, tangible infrastructure project that gives the DR Congo and Angola another route and another partner to work with. For both African nations involved, this isn't just about picking a side in a broader geopolitical rivalry. A faster, more reliable export route, regardless of who finances it, means better prices for their mineral exports and less dependence on any single trading partner or transport route.

Whether the corridor delivers on its promised timeline and cost savings will depend heavily on execution: railway modernisation projects in the region have a long history of delays, cost overruns, and shifting political commitments. But the ambition behind it captures something important about how global competition over critical minerals is playing out in 2026. It is increasingly fought not through diplomatic statements or trade agreements alone, but through the far more physical question of who controls the roads, ports, and railways that move the raw materials the modern economy actually runs on.
