Odaily News Chen Fengxiang, a visiting professor and assistant director of the MBA program at City University of Hong Kong, said that the international payment system that the BRICS countries are planning to build is similar to mBridge. Hong Kong has many years of experience. If mBridge operates smoothly, it will not be difficult to add several currencies. mBridge uses blockchain technology, and central banks directly use local currencies for settlement, which can perfectly avoid the risk of sanctions.
