China shakes the world with its rise at the end of the 20th century. China has become a world power not only in its rapid economic growth but also in competitive sports. This article discusses how competitive sports have such a soaring growth in China, with literature analysis and historical retrospect research as research methods. Start with the early dark period of turbulent domestic conditions and isolated international relations to the world power nowadays. The analysis concludes three major factors behind this rapid growth of competitive sports in China: first, the national sports policy enables "one lash method" of unified sports training system. Second, the strong motives of being elevated to higher social status strengthen athletes' motivation to training. Third, communism in China grants strong national identity through people. The unique cultural ideology and development background are the reasons behind this rapid growth of competitive sports in China. However, stepping into the 21st century, China might face several development concerns for its competitive sports. First, the government enforces "one-child policy" to restrain general population, which may cause problems of spoiled children. Families may not be willing to let their beloved children participate in competitive sports. Second, the western ideology trend of democracy and freedom, accompanied with controversial human rights issues will cause tremendous changes in athletes training system. Athletes will no longer be totally controlled by the country. China's changes made great impacts on the whole world. In addition, as the Beijing Olympics speeds up development in China, China's schedule of being the most advanced country in the world could be shortened. In the 21(st) century, Olympics will have more oriental culture lay on the existing western foundation, which enables Olympics become a real international cultural property.
