Its location in the center of Africa has made D.R.C. a key player in the region since independence. Because of its size, mineral wealth, and strategic location, Zaire was able to capitalize on Cold War tensions to garner support from the West. In the early 1990s, however, in the face of growing evidence of human rights abuses, Western support for the incumbent government waned as pressure for internal reform increased.

D.R.C.'s relations with neighboring countries have often been driven by security concerns, leading to intricate and interlocking alliances. Domestic conflicts in the Central African Republic, Sudan, Uganda, Angola, Rwanda, and Burundi have at various times created bilateral and regional tensions. The current crisis in eastern D.R.C. has its roots both in the use of the Congo as a base by various insurgency groups attacking neighboring countries and in the absence of a strong Congolese Government with a military capable of securing Congo's borders. The war has been exacerbated and prolonged by the exploitation of Congo's resources by neighboring countries.
