What's not represented

  • · Local Congolese civilians living under M23 administration
  • · Artisanal miners forced to work in rebel-held sites

Why this matters

The de facto annexation of eastern Congo places a massive share of the world's critical minerals—essential for smartphones, electric vehicles, and defense tech—under the control of an unsanctioned rebel administration. The conflict threatens to ignite a broader regional war in central Africa while severely disrupting global technology supply chains.

Key points

  • The Rwandan-backed M23 rebel coalition has established parallel administrative structures across North and South Kivu.
  • Human Rights Watch and UN experts classify Rwanda's involvement as a 'belligerent occupation' due to its effective control of the region.
  • The DRC has filed a formal case against Rwanda at the International Court of Justice over the territorial capture.
  • Rebel forces now control the Rubaya mine, which supplies an estimated 15% of the world's tantalum.
  • Diplomatic efforts, including the US-brokered Washington Accords, have failed to halt the violence or the rebel advance.

The borders of central Africa are being quietly redrawn. In the eastern Democratic Republic of Congo, the Rwandan-backed M23 rebel coalition has established parallel administrative structures across North and South Kivu, effectively annexing two of the country's most resource-rich provinces.[3]

The scale of the territorial capture represents the most significant shift in the region's balance of power in decades. After a lightning offensive that began in early 2025, the rebels—now operating under the broader Alliance Fleuve Congo (AFC) umbrella—control major provincial capitals including Goma and Bukavu.[3][4]

Rather than simply occupying military outposts, the M23 has transitioned into a governing authority. Local reports indicate the group is levying taxes, appointing administrative officials, and controlling border crossings, cementing a de facto partition of the DRC.[3]

The Congolese government in Kinshasa has responded by opening a new legal front, filing a formal case against Rwanda at the International Court of Justice. The DRC accuses its neighbor of orchestrating the rebellion to plunder its natural resources and destabilize the state.[1]

The M23 and allied forces have consolidated control over major population centers in North and South Kivu.

International monitors have largely corroborated Kinshasa's claims. A sweeping June 2026 report by Human Rights Watch, alongside findings from UN experts, concluded that the Rwanda Defence Force exercises "effective control" over the rebel-held territory, meeting the international legal threshold for a "belligerent occupation."[2]

The human toll of this territorial consolidation has been catastrophic. The United Nations estimates that the recent offensives have displaced hundreds of thousands of civilians, exacerbating a nationwide crisis that has left 21 million Congolese in need of urgent humanitarian aid.[4]

Human rights investigators have documented rampant abuses within the occupied zones. Both M23 fighters and Rwandan military personnel have been implicated in arbitrary detentions, extrajudicial killings, and the forced recruitment of civilians—including children—into their ranks.[2]

Kigali vehemently denies these allegations. The Rwandan government maintains that it does not support the M23 and insists that the DRC is collaborating with the FDLR, a Congo-based Hutu militia that includes remnants of the perpetrators of the 1994 Rwandan genocide.[6]

For M23 leadership, the territorial takeover is framed as a necessary measure to protect ethnic Tutsis in eastern Congo from targeted violence and systemic discrimination by Congolese state forces and allied militias.[6]

Yet, geopolitical analysts point to a more lucrative motive: critical minerals. Eastern Congo is a geological treasure trove, and the rebel advance has systematically targeted major mining hubs.

The crown jewel of this captured territory is the Rubaya mine in North Kivu. The site is estimated to supply over 15 percent of the global production of tantalum, a vital component in smartphones, electric vehicles, and advanced defense systems.

The captured Rubaya mine alone accounts for an estimated 15% of the world's tantalum supply.

By controlling Rubaya and surrounding extraction sites, the M23 and its backers have secured a chokehold on a critical node of the global technology supply chain, funneling untaxed minerals across the porous eastern border.

This economic reality has deeply complicated international mediation efforts. The United States, which brokered the fragile Washington Accords in mid-2025, finds itself caught between condemning the rebel advance and securing access to the very minerals the rebels now control.[4]

Diplomatic initiatives have repeatedly stalled. Despite a recent commitment by both Kinshasa and Kigali to "de-escalate tensions" during talks in London, fighting on the ground has continued unabated, with M23 forces clashing with Congolese troops and allied "Wazalendo" militias.[5]

The United Nations peacekeeping mission, MONUSCO, has proven largely powerless to halt the rebel advance. Constrained by its mandate and outgunned by the sophisticated weaponry deployed by the M23, the UN force has been reduced to monitoring a ceasefire that exists only on paper.[4]

As the conflict grinds on, the risk of a broader regional war looms large. The DRC has heavily militarized its remaining positions, while neighboring countries watch nervously as the security architecture of the Great Lakes region fractures.[1][4]

For the millions of civilians trapped in North and South Kivu, the geopolitical maneuvering offers little relief. They remain caught between a retreating national army, a deeply entrenched rebel administration, and a global economy hungry for the earth beneath their feet.[2][3]

Viewpoints in depth

Kinshasa & Rights Groups

Argues that Rwanda is conducting an illegal war of aggression to annex Congolese territory and plunder its mineral wealth.

The Congolese government, backed by findings from the UN and Human Rights Watch, views the M23 not as a domestic rebellion, but as a proxy extension of the Rwanda Defence Force. They point to the sophisticated weaponry, drone capabilities, and direct troop support as evidence of a 'belligerent occupation.' For Kinshasa, any peace process that treats the M23 as an independent political actor legitimizes an illegal land grab designed to funnel Congolese coltan and tantalum into Rwandan export markets.

Kigali & M23 Leadership

Maintains that the conflict is an internal Congolese crisis and frames the rebellion as a defense of persecuted ethnic minorities.

The Rwandan government consistently denies arming or directing the M23, arguing instead that Kinshasa is scapegoating Kigali for its own governance failures. Both Rwanda and the M23 leadership assert that the Congolese military is actively collaborating with the FDLR—a Hutu militia founded by perpetrators of the 1994 genocide. From this perspective, the M23's territorial control is a necessary security buffer to protect ethnic Tutsis in eastern Congo from state-sanctioned violence and ethnic cleansing.

Western Diplomatic Mediators

Prioritizes immediate de-escalation and the stabilization of global critical mineral supply chains over assigning definitive blame.

The United States, the UN, and regional mediators find themselves in a delicate balancing act. While they have condemned the M23's advances and urged Rwanda to withdraw its support, they are also deeply concerned about the global economic fallout of a wider war in a region that produces the vast majority of the world's critical minerals. Their approach focuses on brokering pragmatic ceasefires, establishing monitoring mechanisms, and preventing a total collapse of the Congolese state, often frustrating Kinshasa's demands for severe international sanctions against Kigali.

What we don't know

  • Whether the International Court of Justice will issue provisional measures against Rwanda, and if Kigali would comply.
  • How the US will balance its need for critical minerals with the enforcement of sanctions against rebel-held supply chains.
  • If the Congolese military has the capacity to mount a successful counter-offensive to retake Goma and Bukavu.

Frequently asked

Why is Rwanda backing the M23 rebels?

While Rwanda officially denies backing the group, international experts say Kigali uses M23 to secure influence over eastern Congo's lucrative mineral trade and to counter the FDLR, a hostile Hutu militia.

What does 'de facto annexation' mean here?

Although the international borders haven't officially changed, the M23 has established its own parallel government, collecting taxes and enforcing laws in the territory it controls.

Why are the minerals in eastern Congo so important?

The region is rich in tantalum and coltan, which are critical components for manufacturing smartphones, electric vehicles, and advanced defense technologies.

What is the UN doing to stop the fighting?

The UN peacekeeping mission (MONUSCO) is present but has been largely unable to halt the rebel advance due to mandate constraints and the sophisticated weaponry used by the M23.
