There are still various problems in the security challenges and disputes around China; The reunification of the motherland is facing a grim situation; There are complex disputes over maritime rights and interests; The border dispute has not been completely resolved; A few separatist forces affect the security and stability of border areas.

Geographical disadvantage: the particularity of geographical position and geographical environment will restrict the improvement of the surrounding security environment in China for a long time. First, the border is long and lacks natural security barriers, making it easy to be invaded by foreign enemies. Second, the number of strong neighbors is rare in the world, which puts great pressure on China's security. Third, some countries in many neighboring countries still have territorial disputes with me, which makes the security environment around me uncertain. Fourth, the coexistence of many hot spots has made China's security face threats and challenges to varying degrees.

Disadvantages from the social point of view: the United States pursues the policy of "westernization", "differentiation" and containment, and constantly intervenes in our peripheral affairs, posing the greatest threat to China's security; Some countries around me have continuously strengthened their military strength, which has increased the insecurity of our surrounding environment; Economic globalization has brought increasingly prominent economic security problems to China.
