The frequent human activities by the Philippines in recent months have started to cause a certain degree of environmental damage to Xianbin Reef, according to a report released on the coral reef ecosystem of the reef in the South China Sea on Friday.

The report is based on firsthand data from field investigations and remote sensing observations conducted by Chinese scientists from May to July.

The scientists are from the South China Sea Development Research Institute of the Ministry of Natural Resources, as well as other relevant departments and field scientific observation research stations.
