How China Built a 25-Year Lock on Africa’s Critical Minerals

While the Western world spent a decade debating the energy transition, China was quietly locking up the mines that make it possible. The acquisitions were unglamorous, the jurisdictions were difficult, and the headlines were small. The result was not.

OECD data now confirms 79 Chinese-linked mines across Africa, concentrated in copper, cobalt, and lithium, the three commodity classes that sit at the centre of every net-zero supply chain on earth. That position was not assembled by accident. It was built over 25 years through a deliberate architecture of state-backed financing, resource-for-infrastructure deals, and vertically integrated offtake arrangements that Western investors and policymakers are only now beginning to map.

Here is the structure of how that position was constructed, what sustains it operationally, and why the competitive gap is harder to close than most Western strategies assume.

How China turned a Zambian copper mine into a continental strategy

The story starts in the late 1990s, at a copper mine in Zambia called Chambishi. China Nonferrous Mining Corp. (CNMC) acquired a stake in the operation at a time when Western capital was retreating from African mining, chased out by political instability, currency risk, and commodity price troughs. Chambishi was not a marquee deal. It was a proof-of-concept.

What followed was the formalisation of that concept into state doctrine. Three policy instruments turned a single mine investment into a continental strategy:

• The “Go Out” policy (1999): Beijing’s directive encouraging Chinese firms to invest abroad, with state financing and diplomatic support as incentives
• The Forum on China-Africa Cooperation, or FOCAC (2000): A multilateral platform that gave China direct diplomatic architecture across the continent
• Resource-for-infrastructure deals (from 2008): The Sicomines model in the DRC, which bundled mineral access with large-scale construction commitments

Each instrument built on the one before. The “Go Out” policy provided the commercial incentive. FOCAC provided the diplomatic channel. And the Sicomines agreement provided the deal structure that no Western lender could match.

The Sicomines model: when infrastructure became the entry price

The 2008 Sicomines agreement in the Democratic Republic of Congo (DRC) changed the scale of what was possible. Under the deal, Chinese firms secured access to copper and cobalt deposits in exchange for commitments to build roads, rail, and power infrastructure.

This structure bypassed the conventional debt and equity risk calculus that Western project financiers apply. It was not a loan. It was not equity. It was a package, and it became replicable. Of the 38 Chinese-linked mines now operating across the DRC and Zambia, 35 are copper and cobalt operations. The model that started at Chambishi is now the default operating structure in the continent’s two most important copper-cobalt jurisdictions.

The operational toolkit that lets Chinese firms go where others will not

Describing China’s African mining advantage as “state backing” captures one instrument out of five. Chinese firms deploy a layered toolkit that, taken individually, is replicable. Taken together, it is not. The five instruments operate simultaneously:

• State financing: Concessional loans from China Exim Bank and China Development Bank that price risk below commercial rates
• Equity stakes: Direct ownership of mining assets, from minority positions to full control
• Offtake contracts: Long-term agreements routing African mineral output into Chinese refineries
• Diplomatic cover: Bilateral relationships cultivated through FOCAC that smooth licensing and regulatory access
• Equipment leasing: Chinese-manufactured mining equipment supplied on favourable terms, reducing upfront capital requirements for operators

No single instrument explains the advantage. A Western firm could, in theory, match any one of these. Matching all five simultaneously, across multiple jurisdictions, requires an institutional architecture that does not currently exist outside the Chinese system.

The state coordination mechanisms that route Chinese capital into African mining operate through a set of interlocking institutions, including policy banks, state-owned enterprise mandates, and bilateral diplomatic frameworks, that function as a system rather than as independent actors pursuing independent agendas.

The processing dominance data completes the picture of why this toolkit is so difficult to counter.

Chinese firms are estimated to control approximately 80% of global cobalt processing and 71% of lithium processing, with broader critical mineral processing dominance estimated at 87-92% globally. These figures, while not independently verified across all sources, are directionally consistent and explain why upstream mine ownership alone does not confer supply chain independence. Control of the processing layer means Chinese firms do not need to own every mine. They control the only scalable route to market.

What this tells you is that a competitor winning an African mining licence is not the same as winning supply chain independence. The midstream chokepoint matters more than the upstream asset, and that chokepoint is firmly held.

Copper, cobalt, and lithium: how the commodity clusters took shape

The DRC and Zambia copper-cobalt corridor is China’s most mature and deeply embedded African position. CNMC alone has pledged approximately $1.5 billion in Zambia, with the Luanshya New Mine Project (Shaft 28) representing a reported $730 million investment designed to produce 43,500 tonnes of copper concentrate annually, with the shallow zone targeting production by August 2026 and the deeper zone by 2028. That pledge is expected to add roughly 133,000 tonnes of new annual capacity across CNMC’s Zambian portfolio.

In the DRC, CNMC’s Msesa copper mine targets production by mid-2028 with estimated capacity of 15,000 tonnes annually, backed by a reported $186.37 million investment. CMOC Group operates the Kisanfu and Tenke Fungurume cobalt and copper operations, further consolidating Chinese control of the DRC’s highest-grade deposits.

The lithium acceleration: a new commodity, the same playbook

The lithium clusters in Zimbabwe and Mali demonstrate how rapidly the copper-cobalt playbook can be applied to a new commodity class. Between 2022 and 2023, Chinese firms executed a compressed acquisition sprint across both countries, deploying the same combination of equity acquisition, integrated offtake, and state financing.

In Zimbabwe, total Chinese investment in lithium is estimated at $1.4-1.5 billion, anchored by Sinomine’s acquisition of Bikita Minerals for $180 million (with a subsequent $300 million expansion), Huayou Cobalt’s purchase of the Arcadia project for approximately $422-528 million, and Chengxin Lithium’s 51% stake in Sabi Star for $77 million.

In Mali, Ganfeng Lithium consolidated full control of the Goulamina project through three sequential transactions totalling approximately $545.7 million, culminating in the buyout of Australia’s Leo Lithium’s remaining 40% stake for $342.7 million. The Ganfeng-Goulamina sequence is the clearest illustration of how Chinese firms use staged acquisition to convert Western-partnered projects into wholly owned supply chain nodes. It is a pattern, not an outlier.

Zimbabwe’s government has since imposed an export ban on raw lithium concentrate, signalling that host governments are beginning to push back on extraction without local processing. That dynamic matters for every section that follows.

Zimbabwe’s lithium export restrictions mark a significant shift in sovereign leverage; the ban on raw concentrate exports forces foreign operators to choose between investing in in-country processing capacity and losing access to one of sub-Saharan Africa’s largest hard-rock lithium resources.

Why the gap exists and why it persists

The question that follows from the data above is straightforward: if Western firms have observed this model for two decades, why has nobody replicated it?

The answer is structural, not financial. Western mining companies operate under commercial lending standards that require project-level returns visible to shareholders. They face ESG mandates from institutional investors that constrain which jurisdictions they can enter and how they can operate. Their political-risk tolerance is set by boards and insurance markets, not by state policy. None of these constraints is irrational. Collectively, they create a systematic disadvantage in exactly the jurisdictions where Chinese firms are most active.

Two competing interpretations of China’s strategy circulate among analysts and policymakers:

• State-directed resource security: US government assessments, including USCC reports, view the expansion as a deliberate strategy to guarantee long-term mineral supplies for China’s industrial base
• Commercial opportunism: Others argue the expansion is driven primarily by commercial demand. China imported roughly one-third of Africa’s mineral and metal exports in 2020 (approximately $16.6 billion), making these investments a rational response to procurement needs

For an investor making decisions today, the distinction matters less than the observable outcome: an entrenched position that compounds year on year.

Supply chain vulnerability assessments conducted by US and allied governments increasingly treat the midstream processing gap, rather than upstream mine ownership, as the primary risk vector; the logic mirrors the article’s own finding that controlling the refinery route to market matters more than controlling individual mining licences.

A 2018 estimate found that Chinese companies controlled less than 7% of the value of total African mine production. That figure, while dated, is a useful corrective to the “complete dominance” narrative. China’s advantage is not in owning every mine. It is in controlling the processing infrastructure through which African minerals must pass to reach end markets. The upstream position enables the midstream lock.

Governance risk complicates the picture for all participants. Countries hosting the largest Chinese mining clusters (DRC, Zambia, South Africa) all score below global averages on the Corruption Perceptions Index. In Cameroon’s gold sector, approximately 200 sites are reportedly operated illegally by Chinese nationals. In January 2025, hundreds protested in South Kivu, DRC, against ecological destruction and illicit exploitation linked to Chinese operators near Kahuzi-Biega National Park.

Recent scholarship on “debt-trap diplomacy” suggests the intentional-entrapment narrative is overstated; transparency risks stem more from local political realities and weak oversight than from a single strategic design. But the community push-back is real, and it creates both reputational exposure for Chinese operators and potential entry points for competitors willing to operate to higher standards.

The Western counter-move and what it has to overcome

US-aligned entities are now actively pursuing deals to secure African mineral output. Three current initiatives illustrate the scale and intent:

1. Orion CMC is reportedly nearing acquisition of a stake in the Kabanga nickel-cobalt-copper project in Tanzania, a prospective investment of $500 million
2. Orion CMC has also pursued investments in Glencore’s copper and cobalt assets in the DRC
3. Project Vault, a US strategic stockpiling mechanism, is reportedly seeking zinc sourced from the DRC’s Kipushi mine

These are real commitments with real capital behind them. They are also late. The structural gap between China’s entrenched position and the Western counter-move is not primarily a capital gap. It is a temporal and architectural gap: China spent 25 years building the financing instruments, diplomatic relationships, and processing infrastructure that make upstream acquisitions supply-chain-relevant. A single deal, however large, does not replicate that architecture.

When host governments become a swing variable

The most active point of structural change is coming not from Western counter-moves but from African host governments themselves. DRC cobalt export curbs and Zimbabwe’s lithium concentrate export ban represent a new sovereign leverage dynamic. These policies affect all foreign investors, but they land differently on operators whose competitive model depends on raw-material extraction without downstream investment in the host country.

For Chinese firms, whose model has historically been built on exporting raw or semi-processed material to Chinese refineries, mandated local processing requirements represent a direct challenge to the value-chain structure that underpins their advantage. For competitors willing to offer local processing partnerships, these policy shifts create an opening that did not exist five years ago.

Western EV and battery manufacturers currently face a binary: buy processed materials that flow through Chinese midstream infrastructure, or pay a diversification premium. Chinese entities reportedly provide over 80% of funding for four major lithium processing plants in Nigeria, extending the midstream advantage into Africa itself. BRI investment announcements in African countries reportedly rose to $33.5 billion in the first half of 2026, suggesting the pace of capital deployment is accelerating, not slowing.

What a 25-year head start actually means for investors navigating this market now

The 79 Chinese-linked mines confirmed by OECD data represent a position built over a quarter century. Combined with estimated control of 80% of cobalt processing and 71% of lithium processing globally, that position defines the competitive baseline against which every new African mining investment must be measured.

Not all of that baseline is fixed. Three categories of contestable terrain exist for non-Chinese investors:

• Exploration-stage assets: Early-stage projects where equity is available before the staged-acquisition pattern can take hold
• Local processing partnerships with host governments: Jurisdictions where export bans and processing mandates create structural preference for operators offering downstream investment
• Governance-premium operating environments: Projects where higher labour, environmental, and transparency standards reduce sovereign risk and attract development finance that Chinese operators cannot access

The OECD figure of 79 Chinese-linked mines across Africa is not an endpoint. It is the baseline from which all competitive analysis of the African critical minerals market must start. The question for investors is not whether this position exists; it is which parts of it are fixed and which parts are currently in motion.

The African critical minerals market is not going to revert to a pre-China baseline. Any investment or policy strategy built on that assumption is misaligned with the evidence. The host-government leverage trend (DRC cobalt curbs, Zimbabwe lithium bans) is the most active point of structural change in the near term, and it is the space where competitive positioning is genuinely being rewritten.
