They have mandates to stimulate local and foreign investments in the country.

The National Investment Corporation of Cameroon (SNI) set up in 1964 and the Investment Promotion Agency (API) created in 2005 are charged with facilitating investment, both local and foreign in the country. While the former has as objective to mobilise and channel national savings and other national and international financial resources, the latter seeks to promote the country's trade mark abroad, propose measures that can attract foreign investors as well as collect information on investment opportunities the country offers. It is also supposed to receive and orientate foreign as well as home-based companies on the steps to follow in setting up businesses. According to a Presidential Decree creating API, the agency is responsible for receiving and forwarding applications for the delivery of investment licences, assisting licensed enterprises in the investment operations, ensuring that the rules and regulations governing investment are respected to the letter as well as propose measures towards putting in place viable sectoral investment codes.

In its vision of generating wealth for the development of the country, SNI provides support to viable and financially profitable economic projects through loans and/or advances to shareholders' current accounts. It serves as a facilitator that receives and accompanies investors as well as financial and technical partners who so desire in the implementation of their projects, its website says. The corporation has as mission to mobilise and channel national savings and all other financial resources towards the financing of economic and social investment operations in the industrial, agricultural, commercial and financial sectors as well as in hotel sub sector. It intervenes notably in setting up projects, carrying out studies and financial transactions aimed at promoting the economic and social development of the country, as well as acquiring or buying shares in companies. It also negotiates debentures, bonds and other negotiable instruments, grants loans or provides backing to companies in which it owns equity in accordance with its internal rules and regulations, conducts studies, evaluates projects and manage investment operations on behalf of the State, public institutions and local public entities and provides technical assistance to third parties for a consideration. Its website says the corporation has participated in the setting up of some one hundred enterprises, some of which today are real engines of growth for the national economy.
