The success of marine environmental regulations in terms of social challenges in Belt and Road Initiative (BRI) countries is the main subject of this study, which compares and contrasts them with an eye toward sustainability, the integration of digital technologies, environmental law, and reducing ecological degradation. Environmental solid governance is essential as BRI countries increase their marine activity, an important part of the world economy by systems thinking; the marine industry includes a broad range of operations about the ocean and its resources through social challenges to promote environmental legislation in terms of emissions in the countries participating in the BRI. This study evaluated the effects of institutional quality and technical advancements in marine policies between 2013 and 2024. This project aims to examine how various policy contexts relate to marine conservation, how well they comply with international environmental regulations, and how digital technology can improve the monitoring and implementation of policies through systems thinking. This study aims to determine common obstacles and best methods for enforcing marine policies by examining research from different BRI countries. The results deepen our understanding of how these policies can be best utilized to meet sustainable development objectives while preventing the degradation of marine ecosystems due to economic growth and business.
