Sure, but China has a less competent industrial espionage than Israel, who has failed to steal the secrets of TSMC's or Samsungs processes for Intel (leaving them trapped on 14nm with a really broken 10nm node in development).
As it turns out, bleeding edge silicon lithography is massively expensive, and the cost to build newer processes balloons every generation. Most of the secrets of each process aren't generalizable between vendors (like how transplanting a design from TSMC 14nm to Global Foundries 14nm would take a fair bit of engineering work).
