I was a little surprised by the offer too. Perhaps then the reasoning behind it would have been that the U.S knows that China does not have the kind of assets needed to protect a carrier. That is of course, a little untrue now, but it still makes some sense. If the PLAN pooled together the majority of it's modern warships, it could definitely escort at least one carrier. But then that would divert ships away from other operations.
In short, a carrier would be a big black hole sucking in rescources for the PLAN at present. But 10 years into the future, that could change.
