Abstract: The goal of the "Viksit Bharat 2047" campaign is to portray India as a fully developed country by the year 2047. The paper explores how the relationship between India and Nepal has changed throughout time. In particular, given India's Neighbourhood First policy, the campaign places a strong emphasis on equitable prosperity and regional stability. Undertakings such as the Cross-Border Electricity Trade are highlighted as the report explores areas of cooperation in energy, trade, infrastructure, and security. Political sensitivity, border issues, and the influence of foreign countries like China continue to be obstacles despite development. The article also examines Nepal's democratic transition and India's assistance in it, arguing in favor of a thorough, long-term strategy for bilateral ties. Under the Viksit Bharat vision, the future of India-Nepal ties rests on mutual trust, improved connectivity, and diplomacy aimed at building a solid, mutually beneficial alliance that supports stability and regional growth. KEYWORDS: 1.
