DRC: “If you resist, we’ll shoot you”: The Democratic Republic of the Congo and the case for an effective Arms Trade Treaty
http://www.amnesty.org/en/library/in...62/007/2012/en
An excellent report, extremely detailed, highlighting the complex commercial relations between DRC and its weapons and ammunitions suppliers. Among those suppliers you will find USA, South Africa, Switzerland, Egypt, France, Ukraine, China… All the usual suspects.

Also from ENOUGH, additional advocacy for a better mandate to MONUSCO:

MONUSCO—Protection of Civilians: Three recommended improvementsAlthough civilian protection is stated to be the highest priority of the United Nations peacekeeping mission in the Democratic Republic of Congo, MONUSCO, the mission continually struggles to fulfill this mandate. Overall, the failure of the U.N. to deal with the FDLR, as a major factor in regional instability, allows for the eastern Congo crisis to fester. The optimal longer term alteration in MONUSCO’s mandate would be to empower and support it, in coordination with other actors in the region, to end the FDLR threat along the lines of the Ituri “Artemis” model. Given MONUSCO’s current mandate on civilian protection, however, this policy brief is focused only on making the existing operation a more successful one.

And finally the dual between DRC and Rwanda is officially on as Lambert Mende, DRC government speaker and information minister, has openly accused Rwanda of supporting the M23 rebel movement.

DRC Government Rules Out Talks With Rebels
DRC Information Minister Lambert Mende says several hundred M23 combatants have been recruited recently in Rwanda.

Mende says the DRC government condemns the inactivity - or worse - of the Rwandan authorities in the face of these serious infringements of the DRC’s peace and security.
He also says the M23 had formed alliances with other armed groups, including the Rwandan FDLR rebels who are operating on Congolese territory.

And the Rwanda answer:
Rwanda: DRC Should Address Its Own ProblemsThe Rwandan government has demonstrated commitment to a peaceful DRC - first, by helping end the previous conflict when it successfully mediated between Kinshasa and the CNDP rebels in 2009, and then actively and openly engaging the DRC to try and find a peaceful settlement of the renewed hostilities.
Ever since the war broke out more than a month ago, Kigali was not only disappointed but responded immediately, as a responsible and concerned neighbour, by organising a series of high-level political and military meetings between the two countries to help contain the situation. Agreements were reached and a joint plan of action drawn.
Unfortunately, Kinshasa has turned around and sought to stab its partner in the back by embracing false rumours and baseless speculation, even as both sides were just about to release results from a joint verification team.
Nonetheless, DRC can still save the situation. It is never too late to make peace. First, Kinshasa needs to acknowledge that the issues in North Kivu are their own and not anyone else's. They should openly engage with anyone who is genuinely willing to help address the issue. Looking around for scapegoats won't provide the answers.

My conclusion remain the same as in the previous post... And the ones before.
