I think China is being way too passive with these sanctions. For example they should either ban or put tariffs on usage of Micron memory chips in China. China needs to be proactive in removing US chips and equipment from the global supply chain. The US has gone way too far.
If this is a competition as defined by seeking semiconductor self sufficiency while maintaining operation of industries where semiconductors are needed, then tactical moves like counter bans or tariffs may or may not be useful in achieving that goal.
This competition is one which is defined by the US and China carrying out their respective strategies.
The US aims to undermine, delay and hinder Chinese semiconductor industry development and self sufficiency.
China aims to advance, progress and speed up their semiconductor industry development and self sufficiency.
If a Chinese response may be able to deter or delay further escalation (if such further escalation is deemed threatening or damaging), then sure perhaps a response would be useful.
But if it does not provide a useful effect, then a response like a counter ban or counter tariff may end up simply being a waste of effort at best, or a potential unforced error at worst.
Responding for the sake of responding is not necessarily useful.
