More information is as follows:
As a socialist country, China has always adhered to the five principles of "peaceful coexistence" in its foreign relations, and publicly promised to the world that it will never seek hegemony, never become a superpower, never be the first to use or threaten to use nuclear weapons, never use or threaten to use nuclear weapons against non-nuclear countries and regions, never invade other countries, and strategically adopt a defensive posture.
The purpose of China's national defense construction is to oppose the war of aggression, safeguard world peace, and safeguard national security and development. In the use of national defense forces, adhere to the position of self-defense and implement the strategic policy of active defense. Therefore, China's national defense belongs to socialist national defense, defensive national defense and independent national defense.
Based on the national conditions and seeking truth from facts, this is the basic principle of national defense construction put forward by Zhou Enlai. In the early days of the founding of New China, the long-term imperialist aggression and feudal rule made China accumulate too much poverty, the industrial base was extremely weak, the national defense industry was very backward, and financial resources were scarce.
Zhou Enlai also put forward the idea of combining peacetime with wartime, that is, "combining peacetime with wartime, bringing the army into the people". China's national defense is defensive, and the war depends on the sum of manpower, material resources and scientific and technological development. China's future anti-aggression war must be mobilized by the whole people, which determines that national defense construction is not only the task of the national defense industry and the army, but also the heavy responsibility of the broad masses of the people on all fronts and departments.
Zhou Enlai pointed out in the report "Struggle for Consolidating and Developing People's Victory" made on September 30, 1950: "After liberating all the land, the people of China need to resume and develop their industrial and agricultural production and cultural and educational work in a peaceful and non-threatening environment." To achieve this goal, we must rely on a strong national defense force.
