The announcement of the new group comes days after Kabila delivered an address in which he said he would set out how Congolese people should act to “rescue” their country.
On Friday, Kabila accused President Félix Tshisekedi’s government of disregarding proposals he had put forward last year, including some aimed at ending the conflict in eastern DR Congo.
Kabila also accused the government of undermining constitutional rule, mismanaging the economy and failing to improve security. He further alleged arbitrary arrests of political opponents and military officers.
The government has not publicly responded to those claims.
Kabila, 55, ruled DR Congo from 2001 until January 2019, when Tshisekedi took office following a disputed election.
The two were once political allies, forming an informal power-sharing arrangement after the transfer of power. They later fell out and Kabila went into self-imposed exile in 2023 before returning to Goma last year.
The former president had remained largely out of public view for several years but has become increasingly critical of his successor’s administration.
The formation of the new coalition comes at an uncertain time in a country that has been wracked by violence for decades.
More than 100 militia groups are active in eastern DR Congo amid ethnic tensions and fighting for political power and control of lucrative natural resources.
The UN and Western governments accuse Rwanda of backing the M23 and controlling the rebels.
Rwanda denies supporting the M23 despite overwhelming evidence, and says its military presence in eastern DR Congo is a defensive measure against threats posed by Congolese armed groups.
Tshisekedi’s second term ends in 2028 but in May he said that elections, which are due then, may not be held because of the conflict.
He also hinted that he may seek re-election for a third term “if the people want”.
The parliament has since passed a bill that could pave the way for a referendum that could remove the constitution’s two-term limit.
Last month, authorities clashed with protesters holding demonstrations in the capital against the proposed changes.
