The geopolitical contest between the United States and China has entered a decisive phase, with Africa’s rare earth and critical minerals sector emerging as a central battleground. While Beijing accelerates its grip on mineral resources across the continent, Washington is tightening its hold on global shipping routes to counterbalance China’s growing dominance in supply chains.
China has steadily expanded its footprint in Africa, securing access to key minerals essential for electric vehicles, renewable energy systems and advanced manufacturing. Through aggressive investments, Chinese firms now control major mining assets spanning lithium, copper and rare earth elements. These moves have strengthened Beijing’s long-term supply security and reinforced its position as a global industrial powerhouse.
At the same time, the United States is shifting strategy. Instead of competing directly in mining at scale, Washington is focusing on controlling critical maritime chokepoints that underpin China’s energy and trade flows. Routes such as the Strait of Hormuz and the Strait of Malacca have become central to this approach.
Data shows that nearly half of China’s crude oil imports pass through the Strait of Hormuz. Meanwhile, a significant portion of the remaining supply flows through the Strait of Malacca. These routes are highly vulnerable to disruption, and increased U.S. presence has already influenced tanker movements, particularly those linked to sanctioned exports.
As a result, shipping delays and rising transportation costs have begun to affect Chinese manufacturing output. Analysts warn that any prolonged disruption could trigger wider economic consequences, given China’s reliance on stable energy imports to sustain industrial production.
In parallel, Washington is expanding its reach beyond the Middle East. It is strengthening its influence over the Panama Canal and exploring broader military access near Southeast Asia to tighten oversight of maritime flows. This layered strategy reflects a deliberate attempt to gain leverage over China’s supply chain vulnerabilities.
However, China’s dominance in Africa remains formidable. Beijing continues to secure strategic assets, including Tanzania’s Ngualla rare earth project and key mining operations in countries such as the Democratic Republic of Congo, Botswana and Mali. In Nigeria, Chinese-backed investments in lithium processing are also strengthening control over battery supply chains.
These investments go beyond extraction. China integrates mining with infrastructure development, building railways, ports and power systems that connect African resources directly to global trade networks. This end-to-end control gives Beijing a decisive advantage, particularly as it dominates processing and refining capacity worldwide.
Furthermore, Chinese firms are securing long-term supply through early-stage project investments, joint ventures and binding offtake agreements. State-backed financing has enabled projects that often struggle to attract Western capital, reinforcing China’s leadership across the value chain.
China has also demonstrated its willingness to weaponize this dominance. Export controls on rare earth materials and critical inputs have increased sharply in recent years. These restrictions target essential components used in high-tech manufacturing, including semiconductors and defense systems, signaling Beijing’s readiness to respond to geopolitical pressure.
Despite these developments, the United States is recalibrating its approach. By focusing on maritime control rather than direct resource competition, Washington aims to offset China’s upstream dominance with downstream leverage. Strategic reserves and alliances are also being strengthened to support domestic industries and reduce dependency on foreign inputs.
This evolving rivalry highlights a broader shift in global power dynamics. China is consolidating control over resources and production, while the United States is positioning itself to influence how those resources move across the world. As both powers intensify their strategies, Africa’s role in global supply chains will only grow more critical.
