Abstract: Throughout the thousands of years of the nation's struggle for independence and defense, Vietnam has developed a culture rich in traditional values that reflect the Vietnamese people. Currently, the Vietnamese cultural value system is undergoing complex changes due to the rapid transformation of economic, political, cultural, and social conditions, as well as unpredictable domestic and international factors. As we enter the 21st century, with the development of science and technology and international integration, building a national cultural value system is essential for social development, fostering the strength of Vietnamese culture, and ensuring the country's prosperity by 2045. This goal represents the highest aspiration of the entire nation, a crucial and lasting element in the strategy for building a prosperous and happy Vietnam. Keywords: Vietnamese people, cultural value system, national development.
