Book excerpt: This study examines the socioeconomic and political impacts of India's Act East Policy (AEP) on NorthEast India. Utilizing a mixed-methods approach, including surveys, interviews, and focus group discussions across five NorthEastern states, the research evaluates the policy's effectiveness in fostering regional development and integration. Findings indicate significant improvements in infrastructure, trade volumes, and employment rates, with a 50.06% increase in road connectivity and a 188.19% rise in export volume. The study also reveals a 30% decrease in insurgency-related incidents, suggesting enhanced regional stability. However, challenges persist in ensuring equitable distribution of benefits, particularly in rural areas. The research highlights the need for more inclusive governance structures and sustainable development practices to maximize the AEP's positive impact on NorthEast India. This comprehensive analysis provides valuable insights for policymakers and stakeholders involved in regional development initiatives.
