The collision, between a Panama-registered oil tanker and a Hong Kong-registered bulk freighter, occurred at around 8 p.m. Saturday in waters about 160 sea miles east of the Yangtze River's estuary, the ministry said. The 32 missing crew members were all from the oil tanker. All the 21 crew members on the bulk freighter -- all Chinese nationals -- have been rescued, according to the ministry.
Chinese maritime authorities have dispatched eight vessels for search and rescue. After the coordination of China Maritime Search and Rescue Center, the Republic of Korea has dispatched a coast guard ship and a fixed-wing aircraft to assist in the search and rescue.
