The main objective of this article is to assess the effect of the Belt and Road Initiative (BRI) in terms of economic interrelations between Asian countries mainly China, Korea, India and Nepal. China’s Belt and Road Initiative (BRI) is one of the most ambitious economic strategies in modern times that alters the economic, political and social relationship between Eastern and Western societies. It not only improves transport networks and facilitates trade, but also raises GDP of many economies. For China, BRI manifests its intention to become the next global power through bigger market access and economic opportunities. Although South Asia is less developed economically, it has high strategic utility for the BRI, which has drawn attention from China to deepen its relations in the region. On the other hand, South Korea has also emerged as a soft power in Asia. It has been playing a significant role in Asia by contributing the majority of its aid, i.e., 35 per cent in Asian economies and a major share of its FDI, i.e., 34.1 per cent. With the rapidly increasing growth of South Korea, it also has a growing relationship with ASEAN and other South Asian economies such as India to reduce its dependence on traditional trade allies. Moreover, for least developed economies like Nepal, the BRI can bring improved infrastructure, needed technology, managerial talents and greater connectivity to the world. South Korea can yield higher benefits through its relation with South Asia and especially Nepal through expansion of export and market access, access to cheap workable manpower to cope with its rising aging population, and less dependence on traditional allies through its investment in South Asian region.
