Foreign direct investment (FDI) refers to direct investment into production or business operations in a country by a company located in another country, such as by establishing subsidiaries or acquiring domestic firms. Foreign portfolio investment (FPI) involves passive investment in a country's financial assets rather than management control. While both FDI and FPI bring capital into a country, FDI is generally considered longer-term and brings additional benefits like job creation, technology transfer, and infrastructure development. The document outlines the definitions, advantages, and differences between FDI and FPI.
