This study examines the macroeconomic factors and policy dynamics influencing Foreign Direct Investment (FDI) flows from Arab countries to Malaysia during the period 2018-2023. Employing a qualitative research design, the study utilizes semi-structured interviews with key stakeholders, analysis of policy documents, and examination of economic data to provide a comprehensive understanding of this evolving economic relationship. The research reveals that Malaysia's economic resilience, robust GDP growth, and effective fiscal policies have been instrumental in attracting Arab FDI, despite global challenges such as the COVID-19 pandemic. Strategic policy initiatives, including targeted FDI incentives and bilateral trade agreements, have played a crucial role in facilitating investment flows. The study identifies key sectors attracting Arab investment, including real estate, Islamic banking and finance, oil and gas, and tourism. Malaysia's position as a global hub for Islamic financial services and halal industries emerges as a significant factor in its appeal to Arab investors. However, the research also highlights persistent challenges, such as regulatory hurdles, cultural and language barriers, and increasing regional competition. The study concludes that while Malaysia has successfully positioned itself as an attractive destination for Arab FDI, continued policy refinement and focus on high-value, knowledge-intensive sectors are necessary to maintain this position. The findings contribute to the growing body of literature on South-South economic cooperation and provide valuable insights for policymakers, investors, and researchers. Future research directions, including the need for quantitative analysis and comparative studies with other Southeast Asian countries, are suggested to further enhance understanding of these complex investment dynamics.
