Foreign direct investment refers to the investment made by an individual or business in another country, enabling investors to have a direct control over their investments. It can be measured as the capital's movement across national borders, resulting in net foreign direct investment inflow. Foreign direct investment plays a significant role in developing countries, providing long-term capital and advanced technologies. However, it also poses risks such as political changes, negative impact on exchange rates, non-viability of economy, and modern-day colonialism. Real-world examples include China becoming the largest recipient of foreign investment, overtaking the US, while the global economy's delicacy, geopolitical risks, and policy uncertainty have led to a reduction in foreign direct investment.
