Much missing of the point.
From China's point of view the US are operating in Chinese waters. The rest of the world may have decided new islands don't make territorial water, but did China ever agree?
Fundamentally its just not very clever of the US, sabre rattling in dispurted territory, just like allowing Russias neighbours to sign up for Nato wasn't clever. Both look like aggressive moves if you look at it from the other party's POV.
Biting the hand that feeds IT
