Prosecutors submitted video footage of collisions between a Chinese trawler and Japan Coast Guard vessels near the Senkaku islets in September to a Diet committee Wednesday amid an ongoing diplomatic spat between the two countries.

The opposition has been pressing the government and the ruling Democratic Party of Japan to submit the footage to the Diet. The video allegedly shows the Chinese trawler ramming the two coast guard boats.

"It contains the criminal acts that led to the arrest and detention" of the Chinese skipper, Chief Cabinet Secretary Yoshito Sengoku told a regular news conference, after he watched the 7-minute video footage along with Prime Minister Naoto Kan in the morning.
