Because China is one of the biggest I.P. thieves in the world. The likes of Huwei have played that to huge advantage with real losses for U.S. companies. Having an I.P. thief wanting to look at your I.P. or have it in their jurisdiction to "protect them" is different than the norm in U.S. and Europe.

Plus, most products certified in those don't even have to turn in their source code. It's one of the reasons I call bullshit every time companies get such a certification and say it means something.
