Members of the community can cooperate and work together through making contacts with each other sustaining this relation. And thus they learn things that cannot be easily achieved alone or is hard-won. Humans are linked through a series of interconnected networks and tend to have values in common with other members of the network. And by expanding networks constitute an asset that can be considered as a form of capital. Obviously, the more people get to know each other and the more common outlook is found within them, we'll have a richer social capital.

The Regional Comprehensive Economic Partnership (RCEP) is a ground-breaking free trade agreement that encompasses fifteen Asia-Pacific nations, including significant economies such as China, Japan, South Korea, and Australia. The Regional Comprehensive Economic Partnership (RCEP), which was signed in 2020, is one of the most significant free trade agreements in the world. It is comprised of 15 nations, including the ASEAN countries. The primary objective of the paper is to investigate the RCEP as a geopolitical strategy, examining its formation and significance, as well as elucidate on the issues and challenges associated with its implementation in order to effectively promote global trade and regional stability. This article also examines the strategic benefits that are crucial to RCEP member’s interests and the motivations that underlie their participation. The paper employs a doctrinal legal approach to analyse the strategic significance, implications, and formulation of the RCEP. The results indicate that the RCEP substantially improves regional economic integration, reduces economic dependencies, and decreases susceptibility to external trade conflicts. China’s leadership in RCEP, which establishes it as a central participant in regional trade and counters Western influence, supports the Belt and Road Initiative. The agreement enhances intra-regional trade, reduces Western leverage, and cultivates a collaborative framework that transforms the geopolitical landscape of the Asia-Pacific region.
