<p>Most nations, particularly developing countries, are trying to attract foreign direct investment (FDI) to enhance economic growth. Based on inconclusive and diverse empirical findings, the links between FDI and economic growth are a long-lasting discussion. The motivation of this study is to check the effect of Chinese outward FDI stock on the economic growth of the 87 Belt and Road Initiative (BRI) countries in a panel regression analysis. Empirical outcomes specify that FDI, capital stock, and human capital are essential aspects of growth in these countries. Also, the study checked for the effect of US FDI flow and found it more growth-enhancing. The interaction between FDI and human capital is also significantly positive, suggesting that investment adds to economic growth in the host nations in the presence of potential adequate absorptive capability. It implies that raising educational attainment improves human capital by bringing in new knowledge and skills and drawing in innovative FDI, leading to a rise in economic growth. It is suggested that administrations of these nations are required to increase capital stock and build human capital to entice and serve FDI influxes by encouraging the adoption of foreign technologies.</p>
