Can the world’s tech supply chain survive the M23’s tightening grip on eastern DRC’s coltan?

What is really happening in the coltan mines of eastern DRC?

In a damning report released this week, Amnesty International accuses the anti-government armed group M23, which is backed by Kigali, of committing horrific human rights abuses against artisanal miners in the eastern Democratic Republic of Congo. The allegations cast a harsh light on a region where the M23 derives substantial revenue from mineral extraction, raising urgent questions about the true cost of the global technology supply chain.

Since its resurgence in 2021, the M23 has seized vast swathes of territory in eastern DRC, a region rich in natural resources. Among its most prized captures is the mining town of Rubaya, which alone accounts for 15% of global coltan production—a strategic mineral essential for the electronics industry worldwide.

Taxes, denial, and the economics of control

United Nations experts say the armed group has imposed a tax on the production and trade of minerals in Rubaya, a claim the M23 has consistently denied. This taxation system, according to the report, funds the group’s operations and entrenches its control over the local population.

Inside the abuse: summary executions and forced labour

The report, published on Monday, details a pattern of “summary executions,” “torture and other ill-treatment,” “arbitrary detention,” “forced labour,” and “forced recruitment” carried out by M23 fighters at mining sites under their control.

Amnesty International says it gathered information on the summary execution of 18 artisanal miners—in Rubaya, located in North Kivu province, and at the Lomera artisanal gold mine in neighbouring South Kivu province.

Witnesses and families of the victims told the organisation that ten of the miners were beaten to death, two were shot, and six were abducted and later found dead.

Miners also described being severely beaten if they asked for breaks, refused to hand over their ore, or disobeyed orders—even in minor ways. More than 20 miners in Rubaya were held in underground cells and subjected to beatings three times a day by M23 fighters, according to the report.

Why this matters for the global tech industry

The allegations highlight a deeply troubling reality: the coltan extracted from these mines feeds into the global supply chain for smartphones, laptops, and other electronics. As the M23 tightens its grip, the international community faces a stark choice—continue to turn a blind eye or take action to break the link between mineral wealth and human suffering.
