Sun Tianqi, chief accountant of the State Administration of Foreign Exchange, predicted that the future digital currency may be a small amount of funds transfer in cross-border links. And to let Libra have a living space in this field, it depends on whether it can solve the "three oppositions" problem behind cross-border small cross-border payments. Sun Tianqi put forward several regulatory recommendations: 1. Must be licensed to operate; 2. Financial licenses must have national boundaries; 3. Prohibit advertisements related to illegal financial services; 4. Strengthen international regulatory cooperation.
