VIDEO | China Coast Guard blasts Philippine ship with water cannon in disputed waters

It was the second incident this week involving both nations in the South China Sea. One of Asia's most contested maritime sites, Scarborough Shoal is claimed by both the Philippines and China, which calls it "Huangyan Dao".

"We urge the Philippines to immediately cease its infringing and provocative actions," China's coast guard said in a statement, while reaffirming China's sovereignty claims over the disputed shoal.

The coast guard took necessary measures, such as tracking, monitoring, and interception to drive away the Philippine vessels, it added, calling the actions "standard, professional and lawful."
