The difference is probably philosophical. A (non-phev) hybrid is primarily an ICE car in every way. Building hybrids is building ICE cars with a little extra. Building EVs is different.
Honda and Toyota invested a lot in hybrid tech, they probably want to milk that investment more and the hydrogen distraction kept them from also investing in BEV tech. China was basically starting a car industry from scratch so didn’t have those sunk costs to worry about.
