1) China finds the excuse it needed to avoid signing a gas field treaty with Japan.
2) What's your's is mine: Beijing orders a Japanese coast guard ship to stop surveying — in Japan's own Exclusive Economic Zone.
3) War & rumors of war: Chinese dispatch quasi-military ship to the Senkaku islands. At the same time a Hong Kong group will charter a Taiwanese fishing vessel to also make a trip to the Japanese-owned islands. Convenient timing.
[That last story also mentions that Captain Ramboat's grandmother passed away in China during his incarceration for violating Japanese waters. Which is sure to calm the passions of Chinese jingoists.]
4) Taiwanese KMT legislator fans the flames: "“Without government support on both sides of the Strait, efforts by civilian associations of [Taiwan, China and Hong Kong] alone will not be enough and will be to no avail [for Taiwan to help seize the Senkaku Islands from Japan]."
Er, just what are the odds that that "civilian association" [Hong Kong's "Action Committee for Defending the Diaoyu Islands"] is actually a Chinese Communist Party front group? Leading everybody down the garden path to war?
