The UN reported in December that up to 4,000 Rwandan soldiers are fighting alongside the M23 against the Congolese army and FDLR militia group. Rwandan President Paul Kagame has denied accusations that his soldiers are in DR Congo, though he has also simultaneously sought to justify its presence and right to defend itself.

The Democratic Republic of the Congo has asked the NBA, along with Formula 1 and numerous major European soccer clubs, including Arsenal, Bayern Munich and Paris Saint-Germain, to stop doing business with Rwanda as the conflict between the two countries deepens.
