In an increasingly interconnected world, the external sector of the Indian economy has emerged as a pivotal component of national development and global engagement. This book, authored by The Study IAS under the guidance of Manikant Sir, delves into the intricate dynamics of India's foreign trade, foreign direct investment (FDI), and the broader global economic architecture. It aims to provide a comprehensive understanding of these elements, especially in light of recent trends and significant historical events that have shaped the current landscape. The significance of foreign trade cannot be overstated; it serves as a vital engine for economic growth, creating jobs, fostering innovation, and enhancing competitiveness. This book meticulously examines recent trends in India's foreign trade, highlighting how government initiatives such as "Make in India" and various liberalisation efforts have transformed India into one of the world's most attractive destinations for FDI. With FDI inflows reaching record levels, this analysis underscores the importance of these investments in driving technological advancement and infrastructure development. Similarly, this book showcases the evolution of global economic architecture from post-war reconstruction using the Bretton Woods institutions to the emergence New International Economic Order (NIEO). These institutions don’t exist in isolation. It will be much easier to understand their significance and functions if we analyse them in the context of critical economic shifts - like the rise of the neo-liberal economy and the era of multilateralism after the end of Cold War. These events have not only reshaped global economic policies but have also influenced India's strategic positioning in international trade and investment. The Study IAS adopts a unique approach to UPSC Civil Services Examination (CSE). We believe in simplifying your preparation by drawing seamless interlinkages between subjects and topics. By promoting analytical thinking and critical evaluation, this book empowers readers to understand the underlying principles governing India's external sector and its implications for sustainable development. We hope this book brings you one step closer to becoming ‘Thinking Creatures!’
