The CPC's national security thought is a scientific theoretical system, which reflects the party's century long practical exploration of safeguarding national security and has gone through a great process of gradual generation, in-depth development and continuous improvement. The Party's national security ideology has presented different ideological contents in different historical periods, with the value of maintaining national security and social stability as its ultimate goal. Tracing back to the century long evolution of the Party's national security, it highlights valuable experiences such as adhering to the Party's scientific leadership, upholding the fundamental interests of the people, adhering to the correct path of development, and coordinating development and security. To promote the modernization of the national security cause of the CPC, we must adhere to the scientific leadership of the Party, innovate and develop Marxism, promote the organic unity of political security, people's security and the supremacy of national interests, firmly follow the path of national security with Chinese characteristics, and reflect the important contribution of the CPC to the cause of human security in the historic cause of promoting the great rejuvenation of the Chinese nation.
