Phase IFoundation

Background

Overview

India's foreign policy strategy is often framed within the context of a multipolar world, seeking strategic autonomy and balancing relations with various power centers. It impacts global governance, trade, and security dynamics.

The global order has been transitioning from a unipolar system, dominated by the United States after the Cold War, to an increasingly multipolar one. This shift is characterized by the rise of new power centers, challenges to existing security architectures, and a more complex distribution of global influence.
