If I were China ...
... I would start playing the US at their own game and pretty much getting rid of US based tech companies from having/getting a hold in China.
As I understand it, Cisco are pretty much dead in the water in the US - Chinese manufacturers (such as Huawei) can make the same or better equipment for cheaper and (on the face of it) don't have to worry so mich about potential US nefarious interventions although they could still infiltrate Chinese companies.
From there, it'll be a short hop to banning all US companies from Chinese markets due to national security concerns ....
What's good for the goose ...
