China Times: America can't guess China's next step

A China Times article cites an unnamed source, presumably in the US government though that's not explicitly stated only stated in the headline, as saying the US is not sure what China might do in reaction to this UN referendum, that the US therefore must consider a worst case scenario and that the US believes Taiwan has underestimated the threat the referendum could spark.

The article also says the source thinks holding the referendum would make the situation more tense than 1996.

Edit: I actually suspect the reason the article doesn't even cite the source as an American in the article is because the opinion being attributed to the American is being passed THROUGH a Taiwanese guy. The idea is to give the impression it came directly from an American source without actually saying so. Am I paranoid?
