Basic situation of China's security environment

Remember to give me points if you are on duty! Situation 1: China is the strategic subject with the largest number of neighboring countries, the most geographical contradictions and the most complicated situation among Asian countries. Second, the rise of new nuclear forces around China not only poses a threat to China, but also becomes a realistic condition for triggering a chain reaction or external interference. Situation 3: The United States forcibly invaded Central Asia, which was the first time that China directly faced the American military forces on land, and the threat to China's east, west and sea became a reality. Situation 4: Inherent security diseases are developing invisibly, Asia-Pacific countries and the United States are recovering, and China's security is "urgent in the east and heavy in the west". Situation 5: The foundation of China's security forces is weak.
