This paper focuses on how the country's external economic relations fared in realizing economic advancement in terms of attracting foreign investments on one hand, and the roles, experiences, challenges and the impact of the inflow of foreign investments on the Nigeria 's economic growth. Specifically, the study interrogates the impact of Americas' and Chinese investments on the stability in the Niger Delta, social welfare of the citizenry and productivity in the Agricultural sector. Relying on the theory of Post-colonial state which assumes that the post-colonial state is not only a creation of imperialism, but has followed a developmental strategy dictated by the interests of imperialism and its local allies and not those of indigenous population. The study argues that the developing countries are still tied to the apron string of their formal imperial master in a more subtle manner than during the era of naked and direct colonialism, and as such, the benefits of the international economic relations are distributed asymmetrically in favor of the metropolitan countries. The researcher made use of observational technique and qualitative descriptive analysis and relying on secondary sources, relevant data were generated. The paper maintains that Nigeria should redirect her efforts towards mobilizing the domestic human and material resources in order to kick-start overall development of the country instead of predicting her hopes of illusive external capital.
