Since 2013，China’s peripheral security environment has been driven by two forces.One is the US rebalancing strategy towards Asia-Pacific，and the other is China’s new foreign policy practice.By strengthening its direct military presence in the Asia-Pacific region，promoting bilateral alliance system，and creating mini-multilateral ism，the US tries to regulate and check the rise of China.Meanwhile China，through cultivating a New Type of Great Power Relationship with major powers，putting the emphasis on the periphery diplomacy，and enhancing economic ties with ASEAN，south Asian and Central Asian regions，tries to reduce the strategic tension.In the foreseeable future，the interaction between China and the United States will be the primary factor shaping China’s peripheral security environment.
