Anglo American Plc appeared in the UN Group of Experts' list of corporations violating OECD guidelines in the Congo. De Beers, which is part of the Anglo American group, made it onto the same list. AngloGold Ashanti, also part of the group, has been accused of exacerbating the conflict in the Congo as well.[66]
A War on Want report on Anglo American reports that "in 2005 De Beers returned to the DRC in an exploration agreement with the country's main diamond mining company Société Minière de Bakwanga (MIBA), itself implicated in a number of human rights abuses."[67] De Beers holds 19.56% of the shares in an umbrella group called SIBEKA, which, in turn, owns 20% of the shares in MIBA.[68] Amnesty International reports that "dozens of illegal miners are shot dead in MIBA's diamond concessions every year" and "according to MIBA officials, around 10 to 15 suspected illegal miners are arrested every day at the polygoneconcession". Amnesty described the detainment centers as "virtually uninhabitable".[69] MIBA is owned and controlled, primarily, by the Congolese government. The Congolese army is both a huge part of the conflict and also involved in the exploitation of minerals.
