On July 8, at the launching ceremony and the first academic seminar of the Digital Finance Research Open Plan held by Peking University, Yan Shenglin, dean of the Institute of Internet Finance of Zhejiang University, said that the currency is credit. Behind the law is national credit, and the technology giants like Facebook may have higher credit ratings than many sovereign countries. Libra represents the iconic event for tech giants to get involved in finance. At present, the renminbi internationalization index is less than 3%, the degree of internationalization of Chinese banks is about 10%, and the leading international banks can reach about 70%. In comparison, Alibaba and Tencent have a higher degree of internationalization, but there is still a gap compared to the degree of internationalization such as Amazon. Libra's ability to establish cross-border payment relationships in the 2.7 billion community is a big challenge.
