The Belt and Road Initiative (BRI), ostensibly a connectivity and developmental program, was launched by the Chinese President Xi Jinping with the primary objective of connecting the common people in Asia through trade, infrastructure and culture. The initiative is designed to enhance connectivity in areas such as trade, infrastructure, investment, capital and people. That said, since its inception, the project seems to confront certain hurdles such as regional geopolitical complexities and launching of other alternative proposals that tend to hamper its progress. As part of the BRI, the BCIM--EC proposes to connect eastern China with South Asia that will also ultimately connect Southeast Asia through different modes for better economic and cultural connectivity. This paper attempts to evaluate the challenges and opportunities of the BCIM--EC project in the context of South and Southeast Asian nations. The paper concludes that the challenges are rather overriding. [ABSTRACT FROM AUTHOR]
