Chinese Miners Are Poisoning Kolwezi and Congo's Government Is Letting Them

Ask a mother in Kolwezi what the rain tastes like now. Ask her what the dust does to her children's lungs, and why the stream behind her house runs the colour of rust. Then ask why the people who dug the copper and cobalt out of her ground are not the ones paying for it.

This is Lualaba province in the Democratic Republic of Congo, the beating heart of the world's cobalt supply and one of its richest copper belts. Kolwezi sits on wealth that powers the batteries in our phones, our electric cars, and the green-energy promises Western capitals keep making. Yet the residents who live beside those pits now have to sue to be heard. They are taking a Chinese mining company and their own government to court over pollution that has spread through their homes, their farms, and their water. That is not a side story. It is one of the most important environmental cases this country has ever seen, and it deserves our full attention.

Think about what that lawsuit represents. For decades, Kolwezi has been told that extraction is progress. Mines bring jobs, roads, and foreign investment, and the people are asked to be grateful. But gratitude does not filter heavy metals out of a well. A job does not return the health of a child who has been drinking contaminated water for years. When residents describe dust that settles on their roofs, water that changes colour, and illnesses that multiply in the same neighbourhoods downwind of the pits, they are describing a failure that official reports and corporate press releases have been too slow to acknowledge.

The scale of Congo's mineral wealth makes the failure harder to excuse. The DRC produces roughly three quarters of the world's cobalt, and Chinese firms have built a dominant position across its mining and processing chain. The 2008 Sicomines arrangement, which traded Chinese investment in mining for infrastructure promised to Congolese citizens, was sold as a partnership. Fifteen years on, many Congolese still cannot point to the clinics, roads, and power lines that were supposed to be its dividend. Meanwhile, the pits grow wider and the rivers grow more poisoned. Ask yourself who wrote that contract, and who has been left holding the bill.

We have seen this pattern before, and we are watching it repeat across the continent. In Ghana, illegal gold operations have turned rivers into sludge and farmland into wasteland. In Zambia and across the Copperbelt, residents have long complained about contaminated water near mining sites. The same script plays out every time. Extraction is fast, profits flow abroad, regulators are underfunded or compromised, and the bill for environmental destruction lands on the poorest families living closest to the mine. Those families are not statistics. They are neighbours, farmers, and parents.

This is also a question of who holds power. The DRC's constitution guarantees citizens a healthy environment, and its mining code requires environmental safeguards and community consultation. The gap between those promises and the reality on the ground is where the rot lives. When a government names its own mining ministry as a defendant in a suit brought by its citizens, it is confessing that the state has failed to protect the people it exists to serve. Our governments must stop treating their citizens' lungs and water as bargaining chips in investment negotiations.

Let us be precise about what is at stake. Chinese capital is not the only foreign money flowing into Congo's mines. Western firms, Gulf investors, and a web of intermediaries all want a piece of the minerals boom, and many of them have their own records of cutting corners. Western governments that lecture Africa about human rights and climate responsibility have, too often, been quiet when the mines in question serve their battery supply chains. Our demand is not anti-Chinese, and it is not anti-foreign. It is the same demand we make of every investor: meet the standards you claim to uphold, here, on our soil, and be held to them by our courts.

There is a better model, and Africa has already proven it works. Botswana built one of the most respected mining economies on the continent by insisting on transparent partnerships, a strong public share in the revenue, and institutions that do not bend to whoever arrives with the largest cheque. Diamonds turned Botswana from one of the poorest countries on earth into a middle-income success story, not because it was lucky, but because it wrote tough terms and enforced them. Mauritius shows what rule of law and open markets can do for a small economy. Neither country is perfect, but both show that resource wealth need not become a curse when institutions are built to serve citizens instead of the people who extract from them.

So what must happen in Kolwezi? First, the government must publish independent environmental impact assessments for every major mine in Lualaba, and it must do so in plain French and local languages that communities can read. Second, water and soil testing must be carried out by independent laboratories with results made public, not buried in ministry drawers. Third, affected households must receive fair compensation under a clear, transparent process, not discretionary favours handed out to whoever has the right connections. Fourth, the principle of polluter pays must be enforced, with penalties large enough to change corporate behaviour rather than simply become a line item in the cost of doing business. And fifth, the courts must be independent enough to hear this case without fear or favour.

Civil society has a role too. Congolese journalists, lawyers, and community organisers need protection and resources, not harassment. Regional bodies such as the African Union and the Southern African Development Community should put environmental justice on their agendas, and the African Commission on Human and Peoples' Rights should document these abuses and call them what they are. The private sector, including responsible investors, should demand independent audits of their supply chains and refuse to buy minerals that come with contaminated water and sick children attached.

Above all, the people of Kolwezi must be heard, and the rest of us must stop treating their suffering as an inconvenient footnote to the global energy transition. Every electric vehicle, every smartphone, and every "clean energy" pledge rests on ground like theirs. If the batteries are green, the mines should be too.

So here is what we demand. We demand that the Congolese government stop defending the indefensible and open its records to the public. We demand that CMOC and every other mining company operating in Lualaba submit to independent environmental audits and publish the results. We demand that the African Union and regional bodies stop issuing communiqués about investment and start issuing consequences for environmental crimes. And we demand that every African citizen who wears a phone, drives a car, or cheers for green energy ask a simple question: whose lungs paid for this?

The residents of Kolwezi are doing what citizens in a democracy are supposed to do. They are going to court. Our job is to make sure the court hears them, the press reports them, and the world remembers that the cobalt in our pockets was dug out of the lives of people who never got a say. Their fight is our fight. Share this story, press your representatives, and do not let this case disappear into the paperwork.
