Competition law is a tool first employed by countries more than a hundred years ago, to address issues relating to restrictions on competition conducted by private firms. Competition law is still predominantly an instrument to resolve national problems while the dominance of market based economies in the last fifty years, particularly following the collapse of the eastern bloc, in combination with improvements in transport, communications and technology have progressively dismantled national borders and internationalized trade. Against this backdrop, the objective of this paper is to examine the role of stakeholders in the regulation of competition among business enterprises in Cameroon. In carrying out this research, the doctrinal method was engaged, drawing from primary and secondary sources of data. It is therefore, recommended inter alia that, business enterprises should strictly observe and adhere to the mechanisms put in place in ensuring fair competition so as to guarantee a much better level of stability and sustainability in doing business in Cameroon.
