Not impressed with your response... it is entirely relevant if the claim about the regulation is that it will reduce smog, but the smog isn't even coming from cars in CA to begin with.
Your cited article says ~20 percent of the smog might come from China. That still leaves 80% that presumably comes from California or nearby states. Why do you think California should be less concerned about emission standards if it is true that they are getting Asian pollution on top of what is produced in-state?
> The smog from China is not under the control of CA...
Right, which is why it's not relevant.

Try thinking a bit harder.

Even by your statistics, 71% of the smog is local and thus can be reduced. The 29% that cannot is irrelevant.
Thinking a bit harder is good advice, you should try it some time.
