china has the most electric cars, the largest manufacturers, and the most advanced battery production on the planet. their experience with electric vehicles and charging would be a valuable leap forward.
The GB/T is for charging and not in car connections. Tesla already has an arguably better connector NACS or J3400 now.
As for China having the most electric cars on the planet. I don't feel that makes them the experts. China tends to steal / copy technology from other countries and has little innovation them self from my view point. They have the most EV's from heavy government subsidies. Tons of cars in graveyards over there.
