Botswana vs Angola: the fight to control the world's biggest diamond company

As Anglo American moves to divest De Beers, one of the world’s most influential diamond companies, African governments and global investors are assessing what control of the diamond value chain will look like in the next decade.

Anglo American Moves to Exit De Beers

Anglo American has confirmed plans to restructure its portfolio, with a clear intention to exit or reduce its stake in De Beers.

The move forms part of a broader strategy to focus on core assets such as copper and iron ore. While the final structure has not been announced, options under consideration include a full sale, partial divestment, or a public listing.

What is clear is that De Beers is no longer central to Anglo American’s long-term strategy.

That shift places one of the most historically significant companies in the global diamond industry into a period of transition.

What De Beers Represents

De Beers is not simply a mining company. It has, for decades, played a central role in shaping the global diamond market.

Through its control of supply, its aggregation and sales systems, and its influence over pricing structures, De Beers has historically defined how diamonds move from extraction to international markets.

Although its dominance has declined from its peak, it remains a critical node in the diamond value chain, particularly across Southern Africa.

Botswana’s Strategic Position

Botswana is already deeply integrated into De Beers’ operations through Debswana, a 50–50 joint venture between the government and the company.

Diamonds account for a significant share of Botswana’s exports and government revenues. As a result, any change in De Beers’ ownership structure has direct implications for the country’s fiscal stability and long-term economic planning.

Botswana has consistently pursued policies aimed at increasing local value retention, including expanding domestic diamond sorting, valuation, and trading activities.

While no formal acquisition bid has been publicly confirmed, Botswana’s strategic interest in maintaining influence over De Beers’ operations is well established.

Angola’s Expanding Role in Diamonds

Angola has, in recent years, repositioned its diamond sector through policy reforms, increased transparency, and efforts to attract international investment.

Its state-owned company, Endiama, has been central to this shift, overseeing concessions, partnerships, and sector governance.

Angola’s strategy has focused on increasing production, improving market access, and strengthening its role within global diamond supply chains.

There is, however, no publicly confirmed proposal from Angola or Endiama to acquire De Beers or to form a pan-African consortium for that purpose.

Global Capital Is Watching

Beyond African stakeholders, international investors are actively expanding their presence in mining and resource assets across the continent.

Countries such as the
United Arab Emirates,
Saudi Arabia, and
Qatar

have increased investments in minerals, logistics, and energy infrastructure in Africa.

While there is no confirmed bid from these actors for De Beers, their broader strategy indicates sustained interest in securing upstream resource positions and downstream trading advantages.

A Structural Question, Not Just a Transaction

The potential sale of De Beers is not only a corporate event. It raises a structural question about control.

Who owns extraction is only one layer.
Who controls aggregation, pricing, and distribution ultimately determines where value is captured.

For African producers, the issue is not simply participation in mining. It is participation across the full value chain.

What We Know vs What Is Unconfirmed

Confirmed:

• Anglo American intends to exit or reduce its stake in De Beers
• Botswana has a deep and established strategic interest in De Beers operations
• Angola is actively expanding and reforming its diamond sector
• Global investors are increasing exposure to African resource assets

Not confirmed:

• A formal sale structure or buyer for De Beers
• Any official acquisition bid from Botswana
• Any proposal by Angola to form a pan-African consortium to acquire De Beers
• Any active bid from Gulf sovereign wealth funds for De Beers

The Strategic Window

The divestment of De Beers creates a rare window.

It is an opportunity to reconsider how value is structured across Africa’s diamond industry. It is also a test of whether ownership, control, and value capture can align more closely with the countries where diamonds are produced.

The outcome will not be determined by rhetoric. It will depend on capital, coordination, and the ability to structure deals that extend beyond extraction into systems of control.
