The sanctioned companies are Gasabo Gold Refinery Ltd, Bugambira Mines Ltd, Wolfram Mining and Processing Ltd, and Rwinkwavu Mining Corporation Ltd, all based in Rwanda.“The M23 and its supporters are exploiting the DRC’s vast mineral resources – wealth that rightfully belongs to the Congolese people – to finance the purchase of weapons, pay combatants and sustain a destabilising insurgency that has triggered a serious humanitarian crisis,” the Treasury said in a statement received by Al Jazeera on June 25.Conflict driven by mineralsDady Saleh, an economist based in Kinshasa, said the conflict in the eastern DRC has long been shaped by competition over natural resources.“Let there be no mistake. The wars we have been experiencing for 30 years in the eastern region of the country are, above all, economic in nature,” he told Al Jazeera.He argued that external powers often pursue strategic economic interests in conflict zones, citing Russia’s invasion of Ukraine and US policy towards Venezuela as examples.The Treasury said the region’s mineral wealth should be a driver of development rather than conflict, arguing that curbing illicit mineral flows would create space for legitimate business while securing critical minerals for global industries.Saleh said the latest sanctions suggest international attitudes towards Kigali may be shifting.“The DRC’s natural resources have been plundered for decades, both before and after independence. Today, that plundering has intensified and increasingly takes place through proxy actors,” he said.For many Congolese, the sanctions are also seen as a long-overdue acknowledgement of what they say has been happening for years.“We are pleased that the US is gradually coming to understand the underhand tactics Kigali is employing on our territory and that the masks are slowly beginning to slip. We have suffered so much because of our natural resources, which were given to us by the Creator, and that is not fair,” said Nestor Sadiki, a resident of Goma, the capital of North Kivu province.Rwanda’s rejection of the allegationsRwandan officials have rejected allegations linking Kigali to mineral trafficking or support for armed groups.Foreign Minister Olivier Nduhungirehe described the US sanctions as “biased” and “unjustified”, arguing that punitive measures do not resolve the conflict.From Kinshasa to Goma, Congolese hope the latest US sanctions will disrupt illicit mineral networks, though many doubt they will end the conflict on their own [Gallo/Getty Images]He said that if sanctions alone could bring peace to eastern DRC, the war would have ended long ago, and that lasting solutions require shared regional responsibility rather than selective blame.Evidence of cross-border mineral flowsRwanda’s rejection contrasts with findings by United Nations experts and Global Witness, which have documented the movement of conflict minerals from eastern DRC through regional supply chains into international markets.The United Kingdom-based organisation says its research traced links between mines in eastern DRC and export networks in the region, alleging that a significant share of shipments is controlled by a small number of companies.It also says smuggled minerals may enter global electronics supply chains before reaching consumer products.According to the UN Panel of Experts, large volumes of coltan continue to be moved monthly from Rubaya into Rwanda following M23’s takeover of the mine in 2024.The Treasury said ending the illicit mineral trade is essential because it finances armed groups, leads to forced labour and violence, and undermines legitimate mining.“The United States remains committed to a peaceful and prosperous Great Lakes region, with a mining sector free from illicit flows or conflict financing,” the Treasury said.Congolese response and rebel positionKinshasa welcomed the sanctions, arguing they reinforce longstanding accusations that Rwanda benefits from minerals extracted in rebel-held territory.Government spokesperson Patrick Muyaya accused Rwanda of profiting from regional mineral flows, pointing to its refining capacity despite limited domestic production.He wrote on X: “A state, Rwanda, which excels in the role of plunderer, middleman and fence for resources extracted through massacres, rapes and bloodshed,” adding that the sanctions had disrupted what he called a chain of “state-sponsored theft”.Displaced people gather at a camp near Goma after fleeing fighting in eastern DR Congo, where conflict linked to armed groups has forced millions from their homes [Alexis Huguet/AFP]The M23 rebels, who control large areas of eastern DRC, deny benefitting from the mineral trade, saying local miners sell the minerals independently while their fighters provide security around mining sites. The group also accuses Kinshasa of using mineral trafficking allegations to distract from military and diplomatic setbacks.“We have no interest whatsoever in minerals. What matters to us is the survival of the people. We are fighting so that the people can feel safe… We are fighting for strong institutions, not strong individuals,” Kambere Muyisa Lumumba, spokesperson for the AFC-appointed governor based in Goma, told Al Jazeera.Even as international pressure on Rwanda increases, Saleh argued that sanctions should not obscure the broader geopolitical interests shaping the conflict.“The Rwandan leaders had the US’s green light. They were allowed to do whatever they wanted,” he said, describing Washington’s latest actions as “a double-edged sword”.Despite increased international pressure, he said the country’s long-term future ultimately depends on domestic leadership.“We Congolese must not think that the Americans are our solution. They are part of the solution, just like the Chinese and the rest of the world. We must be able to take charge of our own affairs,” he said.
