To speak of the borders of the Democratic Republic of Congo today is to address the question of their security. These borders are subject to constant threat and insecurity. As a result, some neighboring countries of the DRC are blamed for maintaining the criminal enterprise along and within the Congolese borders either by supporting the rebel movements, or by contesting or occupying part of the territory, or even by illegally exploiting national resources. Beyond that, the DRC suffers both from the expansionist behavior of its neighbors and from the absence of effective border protection mechanisms. These expansionist tendencies contribute to the emergence of numerous conflicts between the DRC and its neighbours. Indeed, the geopolitics of securing the borders of the DRC is intended as a strategic approach aimed at developing and mobilizing the significant means of power likely to validly defend its national territory wherever it is threatened. To do this, several prerequisites must be met, in particular the redefinition of neighborly relations, the equipment of defense services and the erection of walls. These prerequisites are materials that can materialize the real protection of the borders of the DRC against external threats.
