The Iranian oil tanker Sanchi has sunk in the East China Sea, after deflagrating at noon. Earlier on Saturday, four Chinese rescuers found two bodies and a black box onboard the vessel. The Chinese Foreign Ministry also on Saturday said China will make a 100-percent effort to rescue the missing crew members. The Sanchi tanker was ablaze for a week after colliding with another ship. It was carrying over 130-thousand tonnes of gas condensate from Iran to South Korea.
