||The TPP is one of the most well-known FTAs in the world, which accounts for 40% of the world total trade amount. According to some scholars, the TPP is an instrument to contain China led by the US, rather than a high-standard FTA. In addition, Japan, as the traditional alliance of the US and the vital trade partner of China, also participates in the TPP, following negotiations. This thesis focuses on Japan’s participation in the TPP and its impact on China. The problem that this paper will endeavor to solve is whether Japan’s participation in the TPP creates predicaments for China. The studies of the TPP differ from the aspect of various countries. By analyzing and comparing the studies inside and outside of China, I hold the view that China is facing an economic predicament and, because of China’s economic influence, a political predicament that is, by contrast, less severe. However, if China’s economic influence decreases due to the economic problems that it faces, the political predicament will be hard to avoid.
