The Strategic Vision and Policies of the Nguyễn Lords and Early Nguyễn Dynasty Rulers Regarding Vietnam’s Southwestern Sea

Abstract

The Southwestern Sea has been one of the essential economic and cultural centers of Vietnam, possessing vast and diverse natural resources. Inheriting the legacy of the Nguyễn Lords, successive Nguyễn emperors since Gia Long established effective governance institutions to manage the seascape, extract minerals, and expand dynastic influence in the area. This article analyzes the objectives and policies enacted by the dynasty regarding this region, examining both their direct and long-term impacts, especially those on Vietnamese sovereignty and socio-economic development in Southern Vietnam, the southernmost part once known as Cochinchina. Thanks to the diverse, prosperous ecosystem of this area as well as the Southwestern Sea and islands, the rapid development of the coastal area is facilitated. Nguyễn Lords and successive Nguyễn emperors paid special attention to the establishment and exercise of sovereignty over maritime spaces to foster economic and social activities formed the essential foundation for the emergence of many inter-regional ports and economic centers. Today, the Southwestern Sea continuously fosters Vietnam’s strategy of blue economy and sustainable development.
