In 2019，China’s balance of payments （BOPs） tended to be basically balanced，and the net external financial claims showed a steady decline. The current account surplus increased steadily under the “stabilizing foreign trade” policy，and the capital and financial accounts remained basically stable and tended to balance under the “stabilizing foreign investment” policy. With the steady progress of capital market financial opening up，combined with RMB internationalization risk monitoring，the following four relationships should be paid attention to and dealt with：（1）The relationship between the complexity of currency competition among large countries and the internationalization of RMB under the international economic and trade frictions. （2）The relationship between the evolution of BOPs and the RMB internationalization under the sustainable structure of BOPs. （3）The relationship between RMB-denominated foreign currency in local currency and RMB internationalization under basically balanced BOPs，and （4）the relationship between cross-border short-term capital flows，exchange rates dynamics，and RMB Internationalization under the BOPs security. To prevent and mitigate financial opening risks，proceed from the BOPs security and RMB internationalization strategy，we must achieve BOPs security，RMB internationalization，the “Belt and Road” construction，and financial sector opening up forming a virtuous circle in the “new era”.
