Bilateral and multilateral relations are significant in UPSC preparation, particularly within the context of India's foreign policy. Candidates must understand the principles governing these relationships to address questions related to international diplomacy and global governance. This involves studying treaties, alliances, and national interests in a global framework. Familiarity with current events enables aspirants to discuss how these relations impact national and international challenges. Well-informed candidates can better analyze policy implications and propose informed solutions, making them stand out in the examination and future roles in governance.
