As part of the China Standardized EMU, the CR400AF is designed to operate at a cruise speed of  and a maximum speed of  in commercial service. Development on the project started in 2012, and the design plan was finished in September 2014. The first EMU rolled off the production line on 30 June 2015. The series received its current designation of Fuxing in June 2017, with the nickname Blue Dolphin. It is among the world's fastest conventional high-speed trains in regular service, with an operating speed of .

Variants
All variants of the Fuxing train are compatible. The EMU models share the same standard required by China Railway Corporation, hence the name China Standardized EMU. Fuxing train models can be identified by the designation. The number in the designation represents the speed class in kilometers per hour. The first letter after the speed is the manufacturer code, with A being the CRRC Qingdao Sifang and B being the CRRC Changchun Railway Vehicles. The second letter after the speed represents whether the train set is powered by self-propelled multiple units or locomotives. Additional variants can be identified with the letter after the dash: No letter indicates the standard 8-car configuration. A indicates a 16-car configuration; B indicates 17-car configurations; C indicates 8-car multiple units with automatic train operation capability; G indicates 8-car sandstorm and cold climate resistant trainset; and Z indicates 8-car configuration with redesigned interior and exterior. Some variants have two letters indicating combined configuration, such as type GZ being the train set featuring extreme weather resistant capability (type G) and redesigned interior and exterior (type Z).
