The two shipwreck sites are relatively well-preserved and contain a wealth of cultural artifacts with a clear historical context, said Song.
"This discovery not only stands as a major achievement in deep-sea archaeology within China, but also holds global significance as a world-class archaeological find," he added.
The discovery of the two shipwreck sites has unveiled a depiction of the bustling maritime trade during the mid-Ming Dynasty. Of particular significance are the Fahua porcelain found in the No 1 shipwreck and the diospyros ebenum discovered in the No 2 shipwreck.
