Philippines summons Chinese envoy over sea confrontations

MANILA, Philippines — The Philippines said it had summoned China's envoy on Monday and flagged the possibility of expelling him following the most tense confrontations between the countries' vessels in years at flashpoint reefs in the disputed South China Sea. 

Videos released by the Philippine Coast Guard showed Chinese ships blasting water cannon at Philippine boats during two separate resupply missions to fishermen at Scarborough Shoal and a tiny garrison at Second Thomas Shoal on Saturday and Sunday.

There was also a collision between Philippine and Chinese boats at Second Thomas Shoal, where a handful of Filipino troops are stationed on a grounded warship, with both countries trading blame.

Diplomatic protests had been filed and "the Chinese ambassador has also been summoned", foreign ministry spokeswoman Teresita Daza told a news conference on Monday. 

Daza said declaring China's ambassador Huang Xilian as "persona non grata" in the Philippines was also "something that has to be seriously considered". 

China's ramming and water cannoning of Filipino boats as well as the use of a long-range acoustic device was a "serious escalation" of their tactics, Jonathan Malaya, assistant director general of the National Security Council, told reporters.

The China Coast Guard, however, said one of the Philippine supply boats deliberately hit its vessel after "disregarding our multiple stern warnings".

China claims almost the entire South China Sea, including waters and islands near the shores of its neighbours, 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 militarised to reinforce its claims.

On Sunday, the US State Department called on China to halt its "dangerous and destabilizing" actions in the sea, while foreign diplomats in Manila also criticised China's behaviour.

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