Invasion of Senkaku/Occupation of Diaoyutai?

I was the video clips on Youtube on the recent incident at Diaoyutai. A Chinese fishing boat was crusing in the sea and two Japanese naval came in to shadow it. Then they moved it to sandwich the Chinese ship and one moved into the path of the Chinese ship to cut it off. The provocative manoeuvre was aggressive. Intentional or not it was not easy to move out of the way or stop a ship in motion, and the Chinese ship brushed the starboard tip at the back of the Japanese ship. It is strange that the picture in the press showed the area of impact on the port side of the ship and almost in the middle section instead. How come? The Japanese video has this headline, China invasion of Senkaku. Now, is it China invasion of Senkaku or Japanese occupation of Diaoyutai? What happened in the incident is similar to the days of foreign concession in Shanghai. The foreigners, British, Russian, French, Americans, Germans, Japanese, etc etc each seized a part of China as their own and police it with their police and applying their own laws, in Chinese territory. Same as in Diaoyutai. Chinese who happened to be in the concession or occupied territories were treated as intruders or foreigners and subject to harassments by the occupied forces. They could be arrested, extorted or humiliated or chased out of the concession. And the occupied forces would declare the Chinese as intruders, or invading their territories. The truth is that the territories belonged to China, Chinese territories, and Diaoyutai is Chinese territories like the Kurile islands which are Japanese territories. The Japanese are demanding that the Russians returned the islands to them, seized from Japan in the same way as Diaoyutai from China. How could the Japanese tell the world that it was a Chinese invasion when they are occupying Chinese territory and harassing Chinese ships in Chinese waters? Bloody imperialist liars!
