Based on research of documents left by Vietnamese feudal dynasties, the current article reports how it initially reconstructed the process of Vietnamese tribute activity of Southeast Asia from the 10th to 19th century and demonstrates the significance of these activities to how Vietnam is considered central rather than peripheral as a nation. Tribute activity took place during a period when Vietnam was an independent country; feudal dynasties of Vietnam were independent and autonomous dynasties. Vietnam had just escaped from the 1,000-year invasion of China and more recently gotten out from the control of the French colonialists. From the demonstration of the tribute activity, otherwise called requesting investiture, the current article places it in relation to the contemporary Chinese “tributary system” to draw out the characteristics and its essence. At the time the current article explores the underlying causes that contributed to shaping the core characteristics of this “tributary system” and its significance to power relationships.
