This
link points to a recent news article discussing new measures to patrol and prevent maritime looting of shipwreck sites around the
Xisha (Paracel) Islands, in the South China Sea. Although a few controlled excavations have been done, according to the article, the scope of illegal wreck diving is severe, and the area to monitor is immense, but officials acting on any further recognition of the problem is a step in the right direction. Some success in boat and artifact confiscation is already reported. Let's wish local authorities even more resources and vigilence.
