Right. Then stop buying them...
Pot meets kettle...................
Good
Sour grapes LOL
Bkmk
China hates it when we do to them like they do to us.
The only downside with all of these is that it highly encouraged China to invest heavily into its domestic chip and other tech-focused innovation and manufacturing. While the native Chinese technology is currently a generation behind leading Western chips, they are still (1) capable enough and (2) continue to advance.
It is like the difference between an F/A-18 E/F SuperHornet and an F/A-18 C/D Hornet. The SuperHornet is a more capable and more modern aircraft in terms of avionics technology than the legacy Hornet, but that is not to say that the legacy Hornet is ‘useless.’
Additionally, China is still receiving the latest chip technology through the black market/hidden purchases, just not in the numbers they need.
TL/DR version: I am not sure what better approach exists, but sometimes limiting the access to technology for a NEAR-PEER country only serves to advance that country’s domestic capabilities. Sure, it hits them hard in the near-term (eg how Huawei was hit hard for a time), but it eventually finds a workaround that is basic at first but becomes more sophisticated with passing time.
