Border, sea, and air defense are important symbols of national sovereignty, important gateways to national security, and important guarantees for national development. The joint efforts of the Party, government, military, police and the people to strengthen border defense are the unique advantages of China's border, sea and air defense, the concrete practice of the socialist system with Chinese characteristics in the field of border, sea and air defense, and an important guarantee for building a strong and stable modern border, sea and air defense. In a series of major actions in border, sea, and air defense, our repeated victories are inseparable from the joint efforts of the Party, government, military, police, and the people to strengthen border defense. It has been proven that there is no force stronger than the joint force, and no defense more rigorous than the joint defense. In the new era, consolidating the joint efforts of the Party, government, military, police, and the people to strengthen border defense is of great significance for strengthening the centralized and unified leadership of the Party over border, sea, and air defense work, creating a joint defense of border, sea, and air by the Party, government, military, police, and the people, and jointly building border, sea, and air borders. Currently, the world's century long changes are accelerating, and the connotation and extension of China's border, sea, and air defense have undergone profound changes. The influencing factors are becoming more complex, and the construction of border, sea, and air defense is facing new opportunities and challenges. Objectively speaking, there is still a considerable gap in China's border, sea, and air defense work: some leading cadres lack unified ideological understanding, and organizational leadership is not strong enough; The prevention and control forces are scattered, and the overall benefits have not been effectively exerted; The development in different regions is not balanced enough, and the situation of widespread participation of the masses has not yet been fully formed; The construction of policies, regulations, institutional mechanisms, etc. lags behind, and the border governance system is not perfect enough. Only by insisting on placing the construction of border, sea, and air defense in an important position in governing the country, strengthening the joint efforts of the Party, government, military, police, and the people to strengthen border defense, and focusing on building modern border, sea, and air defense that is commensurate with China's international status, national security, and development interests, can we ensure that our country's border, sea, and air borders are as solid as gold and indestructible. Preparing for border troops is a top priority for the country Our national defense is the national defense of the whole people, and promoting the modernization of national defense and the army is the common cause of the whole party, the whole army and the whole people. To leverage the advantages of the joint efforts of the Party, government, military, police, and the people in strengthening border defense, we must strengthen the centralized and unified leadership of the Party Central Committee, adhere to political security, prosperity, military strength, diplomatic harmony, and technological control, strengthen overall coordination, improve institutional mechanisms, promote joint management, and advance the rule of law in border defense. We must accelerate the construction of a border governance pattern with the Party committee as the direction, the government as the overall coordinator, the military as the backbone, the police as the governance force, and the people as the foundation, accelerate the construction of the defense and control force system for border, sea, and air defense, promote military civilian joint defense and management, implement relevant safeguard measures, and build a solid wall for border, sea, and air defense. The great handle of the country is not heavier than the military As the backbone of strong border defense, the People's Army should actively communicate and coordinate with local governments, strengthen planning and coordination with the Party, government, police, and the people, and coordinate tasks and resources; We should track, study and judge the development of the international and surrounding security situation, strengthen the preparation for the military struggle of air defense in the border and sea, comprehensively improve the ability to prepare for war in the new era, earnestly assume the major responsibility of safeguarding national sovereignty, security and development interests, and provide strong strategic support for comprehensively promoting the construction of a strong country and the great cause of national rejuvenation with Chinese path to modernization.
