Resource Nationalism in Africa — Mining Codes, Tax Policy, Export Bans, and the Battle for Mineral Sovereignty

The Rise of African Resource Nationalism

Resource nationalism, the assertion of sovereign control over natural resources and the demand for greater national benefit from their extraction, is reshaping the mining landscape across Africa. After decades in which African governments competed to attract foreign mining investment through tax incentives, regulatory concessions, and liberal foreign ownership rules, the pendulum has swung decisively. Governments from Kinshasa to Lusaka to Harare are rewriting mining codes, raising tax rates, imposing export restrictions, and demanding local processing and beneficiation, asserting the principle that Africa's mineral wealth should primarily benefit African citizens and economies.

This shift is driven by several converging forces. The global critical mineral race has made African governments acutely aware of the strategic value of their mineral endowments. When the United States, the European Union, and China are all competing for access to cobalt, copper, and lithium, the leverage of countries that hold these minerals increases dramatically. African leaders have observed that while their countries provide the raw materials for the global energy transition, the value addition, the processing, manufacturing, and profits, occurs overwhelmingly in China, Europe, and North America. This asymmetry has become politically untenable.

Domestic politics reinforce the trend. African populations, better informed and more politically assertive than in previous decades, demand visible benefits from mining. Unemployment, poverty, and environmental degradation in mining communities fuel resentment toward foreign operators who extract wealth while local conditions stagnate. Politicians who promise to reclaim national control over mineral resources win elections. The combination of geopolitical leverage and domestic political pressure creates a powerful dynamic that is unlikely to reverse regardless of which party or individual holds power in any given country.

For foreign investors, including those developing the Lobito Corridor, resource nationalism is both a risk to be managed and a reality to be accommodated. The question is not whether African governments will assert greater control over their mineral sectors but how they will do so, and how investors can adapt their strategies to the new environment.

DRC Mining Code Reforms

The Democratic Republic of Congo, holder of approximately 70% of the world's cobalt reserves and massive copper deposits, has been at the forefront of African resource nationalism. The 2018 revision of the DRC's Mining Code represented the most significant overhaul of the country's mining regulatory framework since 2002 and signalled a fundamental shift in the balance of power between the state and foreign mining companies.

The 2018 Mining Code introduced several transformative provisions. Royalty rates were increased substantially: cobalt and germanium, classified as "strategic substances," were subjected to a 10% royalty rate, up from 2% under the previous code. Copper royalties increased from 2% to 3.5%. The state's free carried interest in mining projects was raised from 5% to 10%, with the possibility of additional increments for project extensions or renewals. Stability clauses, which had protected investors from regulatory changes for ten years under the 2002 code, were reduced in scope and duration, giving the government greater flexibility to adjust fiscal terms during the life of a mining project.

The "strategic substances" designation was perhaps the most consequential innovation. By classifying certain minerals as strategic, the DRC government gave itself the authority to impose higher royalties, restrict exports, and impose additional conditions on their extraction and sale. Cobalt was the immediate target, but the framework is extensible to any mineral that the government deems strategically important, including lithium, rare earths, and other energy transition minerals where the DRC's geological endowment may prove significant.

President Tshisekedi's administration has built on the 2018 code with additional assertive measures. The government has initiated reviews of existing mining contracts, particularly the Sicomines minerals-for-infrastructure agreement with Chinese companies, seeking improved terms and greater transparency. The creation of the Entreprise Générale du Cobalt (EGC) as a state monopoly buyer of artisanal cobalt was another expression of resource nationalism, designed to capture a greater share of the artisanal mining value chain and to improve traceability and working conditions in the sector.

The DRC government has also explored the establishment of a strategic mineral reserve, modelled on the petroleum reserve systems of oil-producing nations. Under this concept, the government would stockpile cobalt and copper, withdrawing them from sale during periods of low prices and releasing them when prices rise, capturing cyclical gains that currently accrue primarily to foreign traders and processors. While implementation has been limited, the policy signals the government's ambition to move beyond simple taxation toward active management of the mineral economy.

Zambia's Evolving Tax Framework

Zambia's approach to mining taxation has been characterised by instability, with fiscal terms oscillating between investor-friendly and state-assertive regimes as successive governments have sought to balance revenue maximisation with investment attraction. This oscillation itself represents a form of resource nationalism, as each new government revisits and revises the terms of the mining social contract.

Under President Hakainde Hichilema, elected in 2021, Zambia has pursued a more nuanced approach that seeks to increase state revenue while maintaining investor confidence. Hichilema, a businessman by background, understood that the extreme fiscal measures attempted by previous governments, including the proposal to replace income tax with a non-deductible mineral royalty at rates up to 10%, had driven investment away without sustainably increasing revenue. His administration has pursued targeted adjustments: maintaining the royalty system but calibrating rates to balance revenue and investment, strengthening the state mining investment company ZCCM-Investments Holdings, and negotiating case-by-case improvements to existing mining agreements.

Zambia's mining tax framework uses a sliding-scale royalty system linked to copper prices. When copper prices are low, royalty rates are lower, protecting company margins and sustaining employment. When prices are high, rates increase, ensuring the state captures a greater share of windfall profits. This system is more sophisticated than flat-rate royalty structures and is designed to reduce the cyclical instability that has characterised Zambian mining policy.

Zambia's resource nationalism extends beyond taxation to ownership and industrial policy. The government has sought to increase the state's equity participation in mining projects, potentially through ZCCM-IH acquiring larger stakes in operating mines. The government has also announced ambitions for local mineral processing, aiming to produce refined copper and cobalt products rather than exporting concentrates. These policies align with the value addition objectives that Western corridor partners support, creating a potential alignment between Zambian resource nationalism and the Lobito Corridor's economic development mission.

Export Bans and Strategic Mineral Controls

Export restrictions on raw minerals have become the most visible and controversial expression of resource nationalism in Africa. Several countries have imposed or considered export bans on specific minerals, seeking to force in-country processing and capture a greater share of the mineral value chain.

The DRC's cobalt sector has been the most prominent arena for export control debates. The government has periodically considered and partially implemented restrictions on raw cobalt exports, seeking to compel producers to process cobalt to at least hydroxide or sulphate grade within the DRC before export. The strategic logic is clear: raw cobalt ore sells for a fraction of the price of processed cobalt chemicals, and the processing margin currently accrues overwhelmingly to Chinese refineries. Forcing in-country processing would, in theory, capture this value within the DRC, creating jobs and industrial capacity.

Zimbabwe implemented one of Africa's most aggressive export bans, prohibiting the export of raw lithium ore in 2022. The ban was designed to compel mining companies, including Chinese operators who had acquired major lithium deposits, to build processing facilities within Zimbabwe. The response was mixed: some Chinese companies invested in local processing plants, while others reduced operations or sought workarounds. The ban demonstrated both the power and the limitations of export controls as a tool of resource nationalism.

Namibia imposed restrictions on the export of unprocessed lithium and other critical minerals in 2023, joining the growing list of African countries using export controls to mandate value addition. Tanzania has explored similar measures for nickel, graphite, and other minerals. The trend is clear: across Africa, governments are moving from passive resource extraction regimes toward active management of mineral value chains through export policy.

The effectiveness of export bans is debated. Supporters argue that bans create irresistible incentives for processing investment, pointing to Indonesia's nickel export ban as a model that has attracted tens of billions of dollars in smelter investment. Critics counter that bans reduce government revenue in the short term, may deter upstream mining investment, and are difficult to enforce in countries with porous borders and limited institutional capacity. The DRC's experience with artisanal cobalt exports, which continue to cross borders through informal channels despite official restrictions, illustrates the enforcement challenge.

The Value Addition Imperative

The demand for in-country value addition is the unifying theme of resource nationalism across Africa. From Kinshasa to Lusaka to Harare, African governments are insisting that the era of exporting raw minerals while importing finished products must end. This demand reflects not only economic calculation but also a deeper political and psychological assertion of sovereignty over the continent's natural inheritance.

The value chain arithmetic makes the case powerfully. A tonne of raw cobalt ore might sell for $5,000-10,000 depending on grade. Processed to cobalt hydroxide, the same cobalt content commands $25,000-35,000. Refined to battery-grade cobalt sulphate, it reaches $40,000-50,000. Incorporated into a battery cathode, the value multiplies further. At each stage of processing, the value captured increases dramatically, and virtually all of that processing currently occurs outside Africa. African governments look at this value chain and see an economic model that replicates colonial extraction patterns, regardless of whether the extracting entities are Chinese, European, or American.

The convergence of African value addition demands with Western supply chain diversification objectives creates a historic opportunity. Western nations need non-Chinese processing capacity. African nations want processing investment. The Lobito Corridor provides the transport infrastructure that makes African processing viable by connecting production centres to export markets. If this alignment of interests is effectively leveraged, it could catalyse a transformation of Africa's role in global mineral supply chains from raw material supplier to integrated producer.

The obstacles are formidable. Processing facilities require reliable electricity, which much of mineral-producing Africa lacks. They require water, skilled workforces, stable regulatory environments, and capital investments that take years to realise returns. The chicken-and-egg problem is real: processing investment requires infrastructure, but infrastructure investment is justified by processing activity. Breaking this cycle requires coordinated investment in both infrastructure and processing simultaneously, exactly the comprehensive approach that the Lobito Corridor is designed to deliver.

Implications for Mining Investors

Resource nationalism creates a fundamentally different risk environment for mining investors in Africa compared to even a decade ago. Investors must now factor higher fiscal burdens, greater regulatory uncertainty, potential export restrictions, and mandatory value addition requirements into their investment calculations.

The most immediate impact is on project economics. Higher royalty rates, increased state equity participation, and windfall taxes reduce the returns available to foreign investors. For marginal projects, these additional costs may render investment uneconomic, particularly in jurisdictions where infrastructure deficits, political instability, and security risks already elevate the cost of doing business. For high-grade, low-cost operations, the impact is manageable: projects with robust margins can absorb higher fiscal burdens while still generating attractive returns.

Regulatory stability has become a critical variable. The frequency with which mining codes and tax rates have changed in both the DRC and Zambia creates planning uncertainty that increases the risk premium investors demand. Companies making twenty-year investment commitments need confidence that fiscal terms will remain within a predictable range over the project's life. Stability clauses, once standard in African mining agreements, have been weakened or eliminated, reducing the contractual protections available to investors.

Local content requirements are expanding. African governments increasingly mandate that mining companies procure goods and services locally, employ local workers at all levels including management, and contribute to community development through social investment programmes. These requirements add costs and operational complexity but also create opportunities for companies that invest genuinely in local capacity building. Companies that develop strong local supply chains and community relationships may gain competitive advantages in licence renewals and new concession awards.

The differential impact on Chinese vs Western operators is significant. Chinese companies, which have historically operated with less transparency and fewer community engagement programmes than Western miners, face particular pressure from resource nationalism measures targeting labour practices, environmental standards, and fiscal compliance. Western companies that already operate to higher ESG standards may find that resource nationalism, paradoxically, narrows the competitive gap with Chinese operators by imposing the governance standards that Western companies already meet.

Impact on the Lobito Corridor

Resource nationalism in the DRC, Zambia, and Angola has direct implications for the Lobito Corridor, both as a transport infrastructure project and as a mineral supply chain initiative.

On the positive side, the corridor's emphasis on value addition, local employment, and community development aligns with the objectives of resource nationalism. The DFC and European development finance institutions that finance the corridor require development impact, including job creation, skills transfer, and local economic benefits, that resonates with African governments' demands. If the corridor can demonstrate that Western-backed infrastructure delivers genuine development alongside mineral transport, it strengthens the political support necessary for long-term operational stability.

On the risk side, the corridor's commercial viability depends on mineral freight volumes, and resource nationalism measures that restrict mineral exports, impose processing mandates, or create regulatory uncertainty could reduce the volumes of mineral cargo available for transport. If the DRC mandates that all cobalt be processed to battery-grade chemicals before export, and the processing capacity does not yet exist within the DRC, the immediate effect would be a reduction in cobalt freight through the corridor until processing facilities are built and operational.

The corridor's multi-country structure adds complexity. Resource nationalism policies differ across Angola, the DRC, and Zambia, creating a patchwork of regulatory requirements that corridor operators must navigate. Harmonisation of mining codes, tax regimes, and trade policies across the three countries is a stated objective of the corridor's institutional framework, but achieving harmonisation across three sovereign governments with different political dynamics and economic priorities is a formidable challenge.

The most constructive approach for corridor developers is to position the corridor not as a challenge to resource nationalism but as a tool for achieving its objectives. A functioning corridor that enables local processing by providing reliable transport for processed minerals to global markets, that creates employment along its route, and that generates tax revenue for all three host governments is an asset to resource nationalist objectives rather than a threat. Framing the corridor in these terms is essential to maintaining political support across successive governments and evolving policy environments.

Navigating the New Landscape

Resource nationalism in Africa is not a cyclical phenomenon that will reverse with the next commodity downturn. It reflects a structural shift in the relationship between African governments and the global mining industry, driven by the convergence of geopolitical leverage, domestic political pressure, and a generational reassertion of sovereignty over natural resources. Investors, corridor developers, and policymakers who treat it as a temporary inconvenience will be consistently surprised. Those who adapt their strategies to accommodate and even leverage resource nationalism will be better positioned for long-term success.

Several principles should guide engagement. First, accept the legitimacy of African governments' demands for greater benefit from their mineral wealth. The historical pattern of raw material extraction with minimal local value capture is both economically inefficient and morally unsustainable. Second, invest in relationships with host governments and communities that demonstrate genuine commitment to shared value creation. Companies that are seen as partners rather than extractors will navigate regulatory changes more successfully. Third, build value addition into project designs from the outset rather than treating processing mandates as obstacles to be circumvented. Projects that include local processing components will be better positioned for long-term political sustainability.

Fourth, support institutional development in host countries. Resource nationalism is more stable and predictable when it is expressed through strong, transparent institutions than when it operates through ad hoc political interventions. Technical assistance for mining code development, revenue management, and regulatory capacity building helps create the institutional infrastructure that benefits both host countries and investors. Fifth, diversify across jurisdictions. The Lobito Corridor's multi-country structure provides inherent diversification, reducing exposure to regulatory changes in any single jurisdiction.

The coming decade will test whether the global mining industry can adapt to a world in which African governments exercise greater control over their mineral wealth. The outcome will shape not only the economics of mining investment but the broader geopolitical competition for critical minerals. Companies and governments that navigate the new landscape of resource nationalism successfully will secure the mineral access that the energy transition requires. Those that resist or ignore it will find themselves increasingly marginalised in a continent that holds the keys to the twenty-first century's most important industrial transformation.
