The COVID-19 pandemic has profoundly impacted the investment policies of developing countries, leading to innovative policy changes and new opportunities for sustainable investment. This conference paper explores the impact of the pandemic on investment policies, the role of international organizations in shaping policy changes, the opportunities for sustainable investment, and the role of technology in the transformation of investment policies. The paper provides case studies from diverse regions, including Latin America, Africa, Asia, the Middle East, and Europe, to highlight how policy changes have been made in practice and their impact on the economy. The case studies demonstrate a range of policy measures implemented in response to the pandemic, including fiscal and monetary support, investment in technology, infrastructure, and social programs, tax relief, and financial support for small and medium-sized enterprises. The paper concludes that innovative investment policies have helped mitigate the economic impact of the pandemic in developing countries and present an opportunity for these countries to continue to attract sustainable investment and promote inclusive growth and economic resilience.
