This paper intends to explore the relation between foreign investment and forced Migration in the context of Colombian armed conflict. Through the illustration of recent cases, it shows the various forms in which the operation of multinational corporations has generated adverse effects to the vulnerable communities located at their area of influence, thus leading to processes of involuntary human mobility. In that way, it is established that there is a symbiotic relation between conflict and development, affecting the structure and scope of the norms concerning both the protection of forced migrants and the attribution of accountability for human rights violations. This is so because there is an economic interest that constrains the recognition of the above-mentioned cases under such legal sphere.
