In order to improve the efficiency of border trade settlement, it is undoubtedly of positive significance to encourage border areas to set up accounts with each other for fund settlement and liquidation. Generally speaking, compared with the countries and regions with active border trade in China, the management level of financial institutions in China is relatively high, the degree of marketization is constantly improving, and the RMB exchange rate is stable and showing an appreciation trend. Therefore, the bilateral settlement of financial enterprises in China is conducive to expanding the profit space of financial institutions in China. At the same time, the RMB circulation of neighboring countries and regions can be brought into the monitoring system of China to a certain extent. In recent years, in the border economic and trade exchanges, the scale of RMB as a payment currency has been rising. However, due to the gaps in laws and regulations and differences in understanding, it is difficult to grasp the real circulation scale of RMB in surrounding areas and countries. If we support and encourage bilateral mutual accounts, it will be conducive to the overseas circulation of RMB into the monitoring system. By promoting RMB settlement business in neighboring countries and regions, it is obviously beneficial to the regionalization of RMB.

With the continuous development of border trade and the expansion of the circulation scale of RMB in the surrounding areas, from the perspective of promoting the regionalization and internationalization of RMB, we should support the use of RMB for border trade settlement and encourage Chinese commercial banks to participate in the RMB settlement business of border trade. In view of the high cost of RMB cash in border trade settlement, commercial banks should be supported to issue other payment instruments including RMB debit cards in surrounding areas. On this basis, cross-border RMB funds should be further included in the information monitoring scope of China's balance of payments and foreign exchange market. Therefore, the regionalization of RMB promoted by border trade settlement is not only the beginning of RMB internationalization, but also provides greater convenience for the development of border trade and international trade in China. On this basis, the financial supervision department should make preparations for expanding the scope and scale of RMB settlement.
