China said a group of its naval vessels, including a destroyer, passed through a waterway between two islands administered by the Japanese prefecture of Okinawa on Wednesday as it returned home after testing far-seas capabilities. Vessel formation 133 dispatched by the People’s Liberation Army’s Eastern Theater Command completed its training in the Western Pacific, and has returned through the Yonaguni-Iriomote Waterway, said the command, which is responsible for East China, the East China Sea and the Taiwan Strait. While non-Japanese vessels are allowed to pass through the narrow band of waters in the middle of the Yonaguni-Iriomote Waterway, Japan reserves the right to take action if vessels stray into the country’s territorial sea, defined as seas 12 nautical miles (22 km) from its shoreline.
