China has put off its mid-September talks with Japan on the controversial East China Sea issue. This is was in protest against seizure of a Chinese fishing boat which had collided with two Japanese patrol vessels near disputed islands,deepening the diplomatic row over the matter. An announcement to this effect was made by Foreign Ministry spokeswoman Jiang Yu said in Beijing. The decision came after a Japanese court granted a request by prosecutors for a 10-day detention of the captain of the Chinese trawler which collided with Japanese patrol ships on Tuesday.
