On the weekend of September 19 to September 21, intense clashes occurred between the Congolese forces and the M23 rebels. Fighting took place in Masisi (North Kivu), Walikale (North Kivu), and Kalehe (South Kivu). This marks the most substantial escalation in the last five or six months.
The escalation is not a surprise, given the occasional flare-ups involving the rebels and the pro-government Wazalendo militia group. Indicators of an impending escalation were visible. The missing of the August 8th and 18th deadlines for commencing direct negotiations and signing a peace agreement. These deadlines were prescribed by the Declaration of Principles signed by the Congolese government and M23 in Doha, Qatar, on July 19, 2025.
The key provisions of the Declaration of Principles include an immediate and permanent ceasefire, restoration of state authority in areas under M23, the exchange of prisoners and detainees, and the alignment of the principles with the June 27 Washington agreement between the DRC and Rwanda. The rebels maintain a presence in multiple territories, including some that were seized in recent weeks.
There are no effective incentives for M23 to halt fighting and conquests. In the past, especially following the Second Congo War, rebel groups sought inclusion in the government. This seems not to be the case with the M23. The M23 recently unveiled 7,000 newly trained fighters. The rebel group stated that 12,000 recruits are currently in training. This indicates its readiness for a protracted conflict. It also hints at the rebel group enhancing its force and order capabilities to effectively oversee local administrative systems in conquered territories.
M23’s motive to keep fighting and control several areas in Kivu is linked to the region’s mineral wealth. Masisi’s mineral deposits include coltan, gold, tourmaline, and diamonds. The Rubaya mine in Masisi is the largest producer of coltan in the DRC. It supplies approximately half of the DRC’s total coltan output and 15% of the global coltan supply. Rubaya’s coltan is processed into tantalum that is used in electronic devices, including laptops and mobile phones.
Of course, there are sociocultural and political factors perpetuating the conflict in the east of the Congo. While these factors that are tied to ethnic groups are still significant in the conflict, they are superseded by geoeconomic interests. Following the M23’s takeover of Goma, North Kivu’s capital, I argued that the conflict had evolved from one driven by ethno-political interests to one fueled by geoeconomic interests.
The conflict in the east not only highlights the DRC’s central role in the global mineral supply chains but also demonstrates the country’s long, troubled history of natural resource curses. An excerpt from David Van Reybrouck’s book, “Congo: The Epic History of A People,” aptly summarizes the DRC’s tribulations despite its rich natural resource endowment:
“There is no other country in the world as fortunate as Congo in terms of its natural wealth. During the last century and a half, whenever acute demand has risen on the international market for a given raw material – ivory in the Victorian era; rubber after the invention of the inflatable tire; copper during the full-out industrial and military expansion; uranium during the Cold War; alternative electrical energy during the oil crisis of the 1970s; coltan in the age of portable telephonics – Congo has turned out to contain huge supplies of the coveted commodity. It has easily been able to meet demand. The economic history of Congo is one of improbably lucky breaks. But also of improbably great misery. As a rule, not a drop of the fabulous profits trickled down to the larger part of the population.“
M23’s significant force capabilities is an impetus for the group to push to establish and retain local administrative systems in the occupied territories. Kinshasa’s incentive is national stability that has been elusive for decades. Achieving this under President Felix Tshisekedi seems illusory in light of his administration’s ineffective handling of the M23 conflict.
Tshisekedi’s administration mismanaged the entire deployment of regional troops from the East African Community (EAC) and the Southern African Development Community (SADC). He demanded the exit of the EAC Regional Force for not engaging the M23 and other armed groups in direct combat. This is despite the regional force’s mandate to supervise the withdrawal of armed groups from captured territories.
The formal exit of the EAC force and the subsequent deployment of the SADC troops in December 2023 did not remedy the situation. And this is the problem with Tshisekedi’s fascination with moments of delusional reprieve. The SADC forces failed to restore stability in the east. The M23 rebels seized Sake, Goma, and Bukavu a year later, in January 2025.
Multiple factors contributed to the failure of the SADC force, which was intended to engage in direct combat with the rebels alongside Congolese troops. The highly limited capabilities of the Congolese forces and the geographical unfamiliarity of the combat zones to the SADC troops stand out.
Tshisekedi turned to the Trump administration for a minerals-for-security support deal signed by the DRC and Rwanda in Washington on June 27, 2025. Its failure was almost certain. On September 22, 2025, President Tshisekedi acknowledged the failure of the deal to end the fighting. He also reiterated that the agreement does not pave the way for auctioning the DRC’s minerals to the US. In mid-September, DRC and Rwanda agreed to start implementing the security measures of the agreement from October 1. This includes the withdrawal of Rwandan troops from the DRC and disarming and eliminating the Forces for the Liberation of Rwanda (FDLR).
The FDLR aims to overthrow the Kagame-led Tutsi majority government in Rwanda. It is active in eastern DRC and is largely made up of the Hutu. The DRC supports the FDLR; the FDLR is to the DRC as the M23 is to Rwanda. It is unlikely that FDLR’s disarmament and elimination will succeed, especially if Rwanda maintains its troops in the DRC and the M23 does not give up its controlled territories. Kinshasa is bound to feel insecure if FDLR is wound up.
The EAC and SADC forces are out, and the US-brokered minerals-for-security deal is unlikely to materialize. This is an ugly juncture for Tshisekedi. His administration is better off sticking with the UN peacekeepers at the moment. While they have primarily been ineffective in containing armed groups in the east over the last 25 years, their presence could help share intelligence with the low-morale Congolese forces.
Tshisekedi’s administration pushed for the exit of the peacekeepers but requested the renewal of the mission’s mandate in December 2024. The departure of UN peacekeepers alongside French forces from Mali without replacement by highly capable security forces has significantly contributed to the escalation of armed conflict. This is probably a key lesson for Tshisekedi.
Some complex possibilities await the Tshisekedi administration. It may consider engaging in a war of attrition against the rebels. But this would require boosting the morale of a poorly paid and equipped military. It is unlikely that the Congolese government will substantially increase the payments for the troops and purchase adequate military equipment in the short term. This means a continued reliance on militia groups whose fighters would be much happier to pocket some francs than eke out a living as overworked miners or desperate small-scale traders. At least looting is guaranteed for militia fighters as a means of survival.
A war of attrition or not (if maneuver warfare is preferred), the recruitment of more foreign mercenaries to fight alongside the Congolese forces and militia fighters is highly likely. Eastern European, Latin American, Middle Eastern, and some African countries are potential sources of mercenaries. Rwandan forces and dozens of armed groups could fight alongside the M23 if Kinshasa opts for a scorched-earth policy. But this would elevate the DRC’s political instability, recalling that conflicts in the east previously led to transitional governments.
