The South China Sea Issue in China’s Policy amid the Establishment of the Indo-Pacific Region

China's policy in the South China Sea in the last decade has demonstrated to the countries of the region that China, for its own national interests, can behave quite aggressively. To a large extent, this policy also influenced the formation of the Indo-Pacific region - a concept promoted by the United States, Australia, Japan, and India, the main aim of which is the displacement of the centers of power in the region to create a structural counterweight to China. This paper aims to answer the question of how China's foreign policy in the South China Sea influenced the formation of the Indo-Pacific region and how it, in turn, can influence China's further policy in the South China Sea. In the work, such theories as Kenneth Waltz's neo-realism and Barry Buzan and Ole Wæver regional security complex theory are used. Keywords: China's foreign policy in the South China Sea, the Indo-Pacific region, neo-realism, regional security complex theory.
