A local court in Japan's Okinawa Prefecture granted on Friday a request by prosecutors for a 10-day detention through Sept. 19 for the captain of a Chinese trawler which collided with Japanese patrol ships off Diaoyu Islands in the East China Sea on Tuesday, according to Kyodo News report.

Zhan Qixiong, the 41-year-old captain, was taken to a local police station on Ishigaki island in Okinawa at around 16:40 local time (0740 GMT) on Friday.

Japan's Coast Guard arrested the captain for alleged "obstructing public duties" early Wednesday despite China's protest.

The other 14 Chinese crew members were not arrested, but were kept on boat off Ishigaki.

Chinese Foreign Minister Yang Jiechi on Friday summoned Japanese Ambassador to China Uichiro Niwa, and lodged protest against Japan's illegal seizure of the Chinese fishing boat in waters off the Diaoyu Islands.

According to a press release from China's Ministry of Foreign Affairs, Yang told Uichiro Niwa that the Chinese government's determination to defend the sovereignty of the Diaoyu Islands and the interests of Chinese people was unswerving.

Yang said China demanded Japan immediately and unconditionally release the boat and all the crew, including the captain.

On Tuesday, two patrol ships of Japanese Coast Guard and the Chinese fishing boat collided in waters off the Diaoyu Islands.

No injuries were reported, but the fishing boat was then intercepted by Japanese patrol boats.
