South Sudan's President Salva Kiir on Thursday toured Rwanda, Burundi and the Democratic Republic of Congo (DRC) in his role as the East African Community (EAC) chairman in an attempt to stem rising tensions between the three neighbours.

President Kiir's first stop was in Kigali in efforts to deescalate the conflict in the Eastern DRC that has intensified since the withdrawal of the EAC Regional Forces (EACRF), whose mandate expired late last year.

EAC Secretary General Dr Peter Mathuki, while in Kigali, said that Rwanda's President Paul Kagame and his counterpart Kiir called for the support of the EAC-led Nairobi Process and Luanda process.

"This is to avert the unfolding dire security situation in eastern DRC, which risks spilling over into neighbouring partner states," said Dr Mathuki.

Luanda Process, led by Angola's President Joan Lorenco, seeks to calm tensions between Rwanda and DRC, who blame each other for fomenting rebellions against their authorities, while the Nairobi Process is a dialogue push led by Kenya's former president Uhuru Kenyatta in an attempt to pacify warring factions inside the DRC by bringing them to the table if they lay down the arms.

Kiir also met with Burundi's President Evariste Ndayishimiye, who has blamed Rwanda for supporting rebels against his government, and DRC President Felix Tshisekedi in efforts to find a common ground to normalise tension between the three EAC member states. Kigali, however, denies both claims by Burundi and DRC.

Since the withdrawal of the EACRF in December last year, fighting between the DRC armed forces (FARDC) and M23 rebels has intensified in the eastern part of the country. Kinshasa accuses Rwanda of backing M23 rebels.

In addition, DRC declined to renew EACRF's mandate after Tshisekedi criticised the regional forces for failing to execute their mission of eliminating the M23 rebels and other armed groups who refused to surrender.

Kigali, on the other hand, denies backing M23 rebels but has also warned that fighting the group, instead of addressing their grievances, could escalate the war.

"The recent M23 rebel advances are due to the DRC's decision to expel the EACRF in December 2023, which oversaw ceasefire and withdrawal efforts," a statement read from Rwanda's Ministry of Foreign Affairs on February 17, 2023.

According to Kagame's government, "Protecting the rights and lives of Congolese Tutsi is the responsibility of DRC. The consistent failure to do so has exposed the entire Great Lakes Region to thirty years of conflict and instability."

On Wednesday this week, African Union Commission (AUC) Chairperson Moussa Faki Mahamat raised the concern of the continuous tension in Eastern DRC calling for a rapid de-escalation.

"DRC and Rwanda should prioritise dialogue in the framework of the two African mechanisms led by President João Lourenço and Uhuru Kenyatta, with the goal of agreeing in a collaborative and fraternal spirit on a reasonable pathway to settle political differences, whatever their nature," Faki said in a statement, adding that there will not be any military solution to problems and disagreements within the African family.

Since the withdrawal of the EACRF in DRC, Tshisekedi has turned to the South African Development Community (SADC), which has since deployed its forces that Kinshasa will fight the M23 rebels.

The bad blood between Burundi and Rwanda has seen Bujumbura close all its land borders with Rwanda in January this year, just less than two years after its reopening.

The decision came after Burundi accused Kigali of supporting, training and funding the Red-Tabara armed group that attacked the country (Gatumba) in December last year, killing at least 20 people.

Kigali rejected the allegations, but Burundi remains the only EAC member state whose army are still in DRC supporting the FARDC and SADC forces in restoring peace and stability in the Eastern DRC. Burundi had also deployed under EACRF.
