A replica 16th century junk has sunk off Taiwan after a collision with a Liberian freighter.
The Princess TaiPing was one day away from completing a trip across the Pacific and back.
Police helicopters and a coastguard ship rescued 11 crew members on Sunday.
The 35-tonne replica of a Ming dynasty warship began its voyage in June last year, sailing along a northern route to Japan. It reached San Francisco five months later.
The voyage was part of an attempt to verify a theory that China's greatest admiral and explorer, Zheng He, sailed to North America 600 years ago.
