The investigation was launched yesterday in Dandong City, Liaoning Province, where the warship was found during an underwater exploration for port construction last year.
Coded 'Dandong No.1', the still intact 50-metre hull is located 10 nautical miles southwest of Dandong Port.
However, the inside of the ship has been badly damaged.
Archeologists have concluded the 1,600-tonne vessel is one of the four warships with the Qing Dynasty (1636-1912 AD) imperial marine forces Beiyang Fleet, which was defeated by the Japanese navy in the Battle of Yellow Sea on September 17, 1894, state-run Xinhua news agency reported today.
