Phl summons Chinese envoy over sea confrontations: foreign ministry 

The Philippines has summoned China's envoy, the foreign ministry said Monday, following two days of confrontations between the countries' vessels in the disputed South China Sea. 

Diplomatic protests had been filed and "the Chinese ambassador has also been summoned", foreign ministry spokeswoman Teresita Daza told reporters. 

Videos released by the Philippine Coast Guard showed Chinese ships blasting water cannon at Philippine boats during two separate resupply missions to flashpoint reefs on Saturday and Sunday.

There was also a collision between Philippine and Chinese boats, with both countries trading blame for the incident.

The confrontations at Scarborough Shoal and Second Thomas Shoal were the most intense between Philippine and Chinese vessels in years, as the countries seek to assert their maritime territorial claims.

China claims almost the entire South China Sea, including waters and islands near the shores of its neighbors, and has ignored an international tribunal ruling that its assertions have no legal basis. 

It deploys boats to patrol the busy waterway and has built artificial islands that it has militarized to reinforce its claims.
