The China Coast Guard on Saturday took necessary measures to drive away three vessels that belong to the Philippine Bureau of Fisheries and Aquatic Resources that were intruding into the waters near China's Huangyan Island in the South China Sea, a spokesperson for the China Coast Guard said on Sunday.

The measures, taken after repeated dissuasion and warnings from the China Coast Guard had been ignored by the Philippine side, were professional and legitimate, spokesperson Gan Yu added.

China has urged the Philippines to immediately stop its infringement and vowed to continue to carry out law enforcement activities in waters under China's jurisdiction in accordance with the law.
