That is very much an untrue generalization and I would suggest you do some independent research on Chinese swords.
My knowledge is admittedly superficial, but that is the overall impression I get.
The double edge jian stop been an important battlefield weapon after the Han dynasty. It was still carried by officers, but mainly as a ceremonial weapon. Jian continued to be favored as civilian weapon of course.
The single edge dao became the dominant form of battlefield sword in China. But both were probably secondary arms on battlefield compare to pole arm and bow/crossbow.
In Europe (less true for Eastern Europe)on the other hand you have the long line of battlefield double edge swords from Roman spatha, viking sword, to knight arming sword and long sword. Unlike in China, double edge swords were the dominant form of battlefield sword in Europe until musket with bayonet replaced infantry sword and Eastern influenced sabre became the dominant cavalry sword.
Correct me if I'm wrong.
