A Study On The Changes Of The U.S.-Philippine Alliance During Duterte Administration

The U.S.-Philippines alliance is one of the most synchronized alliances with the U.S.rebalancing strategy in the Asia-pacific region.The U.S.-Philippines alliance is the "core" of the U.S.rebalancing strategy in the Asia-pacific region,and its development and changes have a direct impact on the situation in the South China Sea.The US-Philippines alliance has experienced a close relationship during the Aquino III administration and a relative estrangement during the Duterte administration,which has brought positive influence to China-Philippines relations,peace and stability of the South China Sea and China's neighborhood diplomacy.The South China Sea has always been a key and difficult area in China's foreign affairs,tensions in the South China Sea have often put enormous strategic pressure on China.Since the U.S.-Philippines alliance provides an important strategic support for the U.S.presence in the South China Sea,the U.S.-Philippines alliance takes the maritime territorial dispute between the Philippines and China as an entry point and exerts great influence on the South China Sea and even Southeast Asian countries.The development of the U.S.-Philippines alliance is driven by the national interests of the two countries in essence,but it is significantly influenced by the personal characteristics of the leaders in practice.From the comprehensive confrontation with China under Aquino III to the comprehensive detente and cooperation after Duterte came to power,this 180 degree reversal is rare in the world,especially when China unable and didn't want to interfere in the internal affairs of the Philippines.We should not only analyze the domestic and foreign policies of the Philippines and the logic of the changing and prospect of its alliance with the Philippines,but also put these situations in the context of The Belt and Road,so that we can find out the rules and trends of the development of the American alliance system and better serve China's foreign policy.The first chapter of this paper introduces the changing background of the U.S.-Philippines alliance.Chapter two introduces the changes of the U.S.-Philippines alliance.Chapter three makes an in-depth analysis of the causes of the change of the U.S.-Philippines alliance from the perspective of the Philippines,including Duterte's political characteristics and his cognition of the national interests of the Philippines.Chapter four analyzes the impact of the changes in the U.S.-Philippines alliance,including the impact on the region and relevant countries in the region,and the impact on the us and its Asia-pacific strategy.
