Increased globalization has ushered in changes in diplomatic purposes and practices. As such, global health diplomacy (GHD) has become a growing field connecting the urgencies of global health and foreign affairs. More academics and policy-makers are thinking about how to structure and utilize diplomacy in pursuit of global health goals. This article aims to explore how the health, peace, and well-being of people in the region can be achieved through global health diplomacy. A systematic review of the literature was conducted on various terms such as “Global Health Diplomacy OR Foreign Policy”; “Disasters”, “Infectious disease epidemics” OR “Non-Communicable diseases” AND “Caribbean” by searching PubMed, Scopus, Embase, Web of Science databases, and Google Scholar search engines. A total of 33 articles that met the inclusion criteria were analyzed, and the critical role of GHD was highlighted. There is an increasing need to understand the complex global health challenges, coupled with the need to design appropriate solutions. Many regional initiatives addressing infectious and chronic diseases have been successful in multiple ways by strengthening unity and also by showing directions for other nations at a global level, e.g., the Port of Spain Summit declaration. GHD has a great scope to enhance preparedness, mitigation, peace, and development in the region. Amid the COVID-19 pandemic, the region needs to strengthen its efforts on equity issues, health promotion, and sustainable development to promote peace and well-being.
