Japanese authorities say they have released 14 crew members of a Chinese fishing trawler seized last week in the East China Sea, BBC reports. But the captain of the vessel remains in custody following the incident, which happened in disputed waters. Prosecutors have until 19 September to decide whether to lay formal charges against him. China has made repeated protests over the incident and warned that it could harm bilateral ties. The Chinese fishing boat reportedly rammed Japanese coast guard patrol boats which had been trying to intercept it. The incident occurred off an island closer to Taiwan than to Japan, and claimed by both Japan and China.
