This article explains the theory of financial repression and international financial power, adopts a comparative empirical approach, and uses the influence of Japan's political and economic system in the 1980s on Japan's international financial power as a reference to discuss the relationship between China's internal financial repression and external financial power. The result shows that China's financial repression system is conducive to the development of China's relational financial power, and is not conducive to the acquisition of structural financial power and institutional financial power. Therefore, in order to enhance China's acquisition of external financial power under the existing financial suppression system, we need to properly handle China's creditor country status, foreign exchange reserves, and rights and responsibilities in the Bretton Woods institutions. At the same time, it is necessary to enhance the international attractiveness of China's financial market and promote the internationalization of the RMB.
