According to "China Foreign Exchange" No. 15 of 2019, Xie Ping of the Wudaokou Finance College of Tsinghua University accepted the interview of "China Foreign Exchange". First, China should actively participate in international organizations such as the International Monetary Fund (IMF) and the Bank for International Settlements (BIS). The activities of digital currency supervision strive to play a role in it. Second, consider allowing Chinese companies to participate in the Libra Association. Third, China can combine the research results of the central bank's digital currency research on the central bank's digital currency, encourage enterprises to participate in the research and application of digital currency, and gradually build a digital currency ecology. It is currently in the pilot and should be applied publicly when appropriate. Fourth, the use of Libra will greatly facilitate hundreds of millions of people to open blockchain application apps or accounts. We want to encourage domestic commercial banks and financial institutions to use blockchain technology. In response to Libra's challenge, the Global Interbank Financial Telecommunications Association (SWIFT) announced in the White Paper on June 20 that it will use blockchain technology to transform its global payment system and prepare for the launch of a new cross-border payment service GPI (Global Payment Innovation). ).
