The Chinese government can beat the war drums all they want, and as loud as they want, and no war is going to happen. It's akin to bullying someone in a wheelchair that you know can't punch back. Conversely, if the Chinese government beat war drums too loud against Vietnam or Japan things might actually get out of hand. If the PLA Navy sent a fleet to a disputed body of water with either of those countries, those countries would send their own boats out to counter them.
That’s a dangerous situation. This is not.
