Introduction

Inside every smartphone is a small permanent magnet. It vibrates your phone when it rings. It moves the camera lens when you take a photo. It drives the speaker that plays your music.

That magnet contains neodymium a rare earth element. China mines and processes the overwhelming majority of the world's neodymium supply.

Inside every electric vehicle motor are more permanent magnets much larger ones. They contain neodymium, dysprosium, and praseodymium. Again, predominantly processed in China.

Inside every wind turbine, every MRI machine, every military guidance system, and every AI data centre cooling system are components that depend on rare earth elements. And across almost every category, China dominates the supply chain with a concentration that has become one of the defining geopolitical vulnerabilities of the 21st century.

The 'Tech Cold War' is extending deep into physical resources, with the periodic table becoming a central battleground. Dozens of naturally occurring elements, particularly rare earths crucial for green technologies and defense, are in growing demand. With China currently controlling the vast majority of the world's supply and refining capabilities, the US and its allies are rushing to counter this influence, planning mining megadeals and proposing 'critical minerals' trade zones, alongside new domestic stockpiling efforts like the US's 'Project Vault'.

In 2026, the race to secure rare earth supply chains has become one of the most consequential and least covered stories in global technology. Here is the complete picture.

What Are Rare Earth Elements and Why Do They Matter?

Rare earth elements are a group of 17 metallic elements including neodymium, dysprosium, lanthanum, cerium, europium, and others with unique magnetic, luminescent, and electrochemical properties that make them indispensable for modern technology.

Despite the name, most rare earth elements are not particularly rare in the earth's crust. The challenge is economic extraction and processing rare earths are typically found in low concentrations mixed with other minerals, and separating them is an expensive, chemically complex, and environmentally intensive process.

China invested heavily in rare earth mining and processing infrastructure from the 1980s onwards a strategic decision that has given it extraordinary leverage over global supply chains forty years later. China currently controls the vast majority of the world's supply and refining capabilities. KEOnline Estimates put China's share of global rare earth processing at 85 to 90 percent a concentration of supply chain control that dwarfs even OPEC's historical influence over oil.

The Devices That Cannot Exist Without Rare Earths

To understand what is at stake, consider what rare earths actually go into:

Smartphones: The vibration motor, camera autofocus, speaker, and microphone all use rare earth permanent magnets. The screen uses europium and terbium for colour phosphors. The battery uses lanthanum.

Electric vehicles: A single EV motor uses 1 to 2 kilograms of neodymium and dysprosium. Global EV production is targeting tens of millions of vehicles annually the rare earth demand is staggering.

Wind turbines: Each direct-drive turbine uses 600 kilograms or more of rare earth permanent magnets. The global wind energy buildout requires rare earth volumes that cannot be met by current supply chains.

Military hardware: Precision-guided munitions, radar systems, sonar, jet engine components, and satellite systems all depend on rare earth elements. This is why the US military has classified rare earth supply as a national security priority.

AI data centres: Cooling systems, power supplies, networking components, and storage systems in AI data centres use rare earth elements across multiple categories.

The AI boom, the EV transition, and the green energy buildout are all occurring simultaneously all competing for the same rare earth elements all primarily sourced from China.

How Nations Are Responding

The global response to rare earth dependency has accelerated dramatically in 2026.

The United States — Project Vault: The US has launched a strategic rare earth stockpiling programme called Project Vault building reserves of critical minerals to buffer against potential supply disruptions. Simultaneously, the US is funding domestic rare earth mining and processing through the Defence Production Act, attempting to rebuild a supply chain it largely abandoned decades ago.

Japan — Mining the Pacific Seabed: Japan is taking an extreme approach to secure these vital materials. A state-backed Japanese expedition recently announced the successful retrieval of rare-earth-rich mud from the Pacific seabed at a staggering depth of 6,000 metres. KEOnline The deep-sea deposit near Minamitorishima Island contains estimated reserves sufficient to supply global demand for decades. The technical challenge of extracting material from 6 kilometres underwater is extraordinary but Japan's strategic need is apparently sufficient to justify the attempt.

Europe — Critical Minerals Partnerships: The European Union has designated a list of Critical Raw Materials and is aggressively pursuing supply partnerships with Canada, Australia, and African nations to diversify away from Chinese sources. The EU Critical Raw Materials Act creates binding targets for domestic processing and strategic stockpiling.

China — Export Controls as Leverage: China has not sat passively while competitors attempt to diversify. In 2023, China imposed export controls on gallium and germanium — critical materials for semiconductors and solar panels. In 2025, it tightened controls on several rare earth processing technologies preventing competitors from easily replicating its processing capabilities. The message is clear: China is willing to use its rare earth dominance as a geopolitical tool.

The African Opportunity — Including Kenya

Here is where the story becomes directly relevant to Africa and specifically to Kenya.

Africa holds significant reserves of many critical minerals. The Democratic Republic of Congo holds the world's largest cobalt reserves. South Africa holds the world's largest platinum group metal reserves. Namibia, Madagascar, Tanzania, and Malawi all have significant rare earth deposits.

The US and its allies are rushing to counter Chinese influence, planning mining megadeals and proposing 'critical minerals' trade zones. KEOnline These trade zones are increasingly targeting Africa making African nations the focus of competing investment from the US, EU, China, and emerging powers like India and Japan.

Kenya itself has deposits of niobium, rare earth elements in parts of the Rift Valley, and significant titanium mineral sands along the coast. The question for Kenya as for all African nations with critical mineral endowments is not whether there will be interest from global powers. There will be enormous interest. The question is whether Kenya can structure that interest in ways that deliver genuine economic development, technology transfer, and domestic value addition rather than simply becoming another source of raw materials extracted and processed elsewhere.

The historical pattern of African resource extraction minerals leave as raw materials, value is added elsewhere, Africans buy the finished products is exactly what the current geopolitical competition creates an opportunity to break. The US, EU, and Western allies are desperate for supply chain alternatives to China. That desperation is leverage — if African governments use it strategically.

For Kenya specifically, the rare earth story connects to a broader digital economy opportunity: the processing and refining technologies for critical minerals are increasingly software-intensive. Environmental monitoring, extraction optimisation, supply chain tracking, and product certification are all software problems. Kenyan tech companies building expertise in mining technology software, environmental monitoring platforms, and supply chain transparency tools are positioning themselves for a market that will grow dramatically as global rare earth investment in Africa increases.

At Rawlinz Designs, we build the digital infrastructure that industries run on from mining technology platforms to supply chain management systems. As Africa's critical mineral sector grows, the digital layer that manages, monitors, and certifies it will be essential.

The Consumer Reality

For everyday consumers, the rare earth war has practical, near-term implications.

The smartphone memory shortage we covered in a previous blog driven by AI data centres consuming chip manufacturing capacity is one manifestation of how supply chain pressures cascade into consumer prices. The rare earth shortage follows a similar logic: constrained supply competing against surging demand from EVs, renewable energy, and AI infrastructure which pushes prices up, which pushes product prices up.

The devices you buy in 2026 and 2027 will cost more partly because the materials inside them are more expensive. The EV you consider buying will have a price premium partly driven by the cost of rare earth permanent magnets. The wind energy powering an increasingly electrified world depends on supply chains that are being actively disrupted by geopolitical competition.

Understanding these connections between geopolitics, supply chains, and the devices in your pocket — is increasingly essential literacy for anyone navigating the technology landscape of 2026.

The Bottom Line

The periodic table has become a battleground. The elements that power your smartphone, your EV, and the AI boom are concentrated in a single country and the race to diversify that dependency is reshaping global trade, military strategy, scientific exploration, and investment flows simultaneously.

Dozens of naturally occurring elements, particularly rare earths crucial for green technologies and defense, are in growing demand. KEOnline Japan is mining the ocean floor. The US is building strategic stockpiles. Europe is signing critical minerals partnerships. And Africa sitting on some of the world's most significant mineral reserves is at the centre of the most consequential resource competition since the oil era.

How this competition resolves will shape the cost, availability, and geopolitical distribution of technology for the next generation. And it's happening right now six kilometres below the Pacific Ocean, in a US government stockpile in Nevada, and in the mineral-rich soil of the African continent.
