Anti-Japan Protests in China: Genuine or Politics

I have been covering stories about spreading protests in China over the so called "Illegal" purchase of disputed islands by Japan. It's very shocking to see the protestors coming out in such huge numbers all across the country especially in a communist state like China where there are so many restrictions and censorship. Intuitively This seems to me as yet another move of Ministry of foreign affairs of China. Evidently the mob was reported to be targeting Japanese nationals, embassies and even Factories and outlets owned by Japanese MNCs. Responding to a request from Japanese Prime Minister to take control of the situation Chinese spokesperson very intelligently tried to blame Japan for the protests and to take the responsibility of any losses incurred to not only it's own people but China as well.
China has so many disputes with numerous countries but this kind of cheap and unsocial tactics only suggests where the dragon may be heading following the footsteps of their ancestor "Dinosauria".
