The true is the Gov don't really need backdoor to any equipment to spy on it citizens. Most that information can be bought by the Gov from a number of company or they can just tap the line. Don't even need a backdoor.
The problem is not it is manufactured in China. It is design in China. It is a lot harder to find any backdoor if it is design into it. Who knows. It may not be a backdoor but a kill switch.
